Node js development services

NodeJS is a technology for the development of applications with a universal purpose. It basically consists of a Javascript execution platform, which is known as a “runtime”, on which all types of programs can be executed.

To explain it in a more practical and understandable way, NodeJS is the Javascript language taken from the browser context. Those who set out to invent it knew how to assess the power of the Javascript language and used the “V8” engine (the open source Javascript engine of the Chrome browser) to create an execution platform capable of taking advantage of the popular language to undertake a wide variety of Projects.

With NodeJS you can build traditional web applications, such as websites. In fact, there are several CMS projects based on Node. However, the most common use of NodeJS is the development of web services that return data in JSON format, which we usually call a REST API. Also with Node we can build multiplatform desktop applications, which have a capacity compatible with Windows, Linux and Mac, as well as console programs. Many day-to-day developer tools are made using NodeJS, from publishers such as Atom or VSCode, to task automaters such as Gulp or asset packers such as Webpack or Rollup.

One of the main characteristics of NodeJS is to undertake many tasks with low resource consumption, which makes it especially interesting for the development of high concurrency services.

Among the main advantages of Node JS are: Speed (runs on Google’s JS engine), I/O paradigm without blocking, data transmission (HTTP requests and responses as a single event), same language (javascript), both on the client and on the server, unified database queries (JSON format), easy and fast coding, good package management thanks to NPM (and Yarn), proxy server capacity, fast development cycles and business logic in the server.

But in case you are still not convinced of the importance of Node JS and its service development, here are some of the companies that use it:

1. Uber: The platform for sharing trips. Uber, is one of the best examples of Node.js applications. The company has doubled in size every 6 months in the last two years. Why? Node.js is ideal for distributed systems that carry out many network requests in order to quickly process large amounts of information. It also has a very intuitive error analysis and rapid code deployment and has constant technological improvement due to the open source community.

2. Ebay: the American e-commerce giant has huge traffic and wanted to work with proven technology. Finally, they chose Node.js, still quite immature at that time, because of the need to make the Ebay application in real time as possible. In addition, they wanted me to maintain an active connection with the servers since, their main objective was to organize a large number of specific eBay services that displayed information on the page, for example, the management of operations linked to I/O.

3. Netflix: The renowned streaming television company chose Node.js for three reasons: the ease with which JS developers learn it, the fact that it eliminated the need to write code twice and high performance. Also with Node.js they reduced compilation times and enabled user customization. As a result, the Netflix team has improved the application loading speed by 70%.

Python Web Development

Web development evolved rapidly. One of the latest bets on the market, with a huge implementation among the community of American developers, is the Python programming language, which allows projects to be carried out in an agile and versatile way. The syntax, written in the late 80’s by Guido Van Rossum – already for version 3.5.0a4. – has become one of the essentials if you are a software developer.

If your idea is to learn python web development, one of the first questions you will have, almost certainly, will be related to what and in what it can be used. Well, the answer is as complicated as the question, because Python can be used for many applications, but if you have to be more specific, we can say that there are applications that are the most popular: data science including machine learning, data analysis and visualization; Web development and Scripting. Let’s see what each one is about.

Data science: Machine learning normally implements an algorithm that automatically detects a pattern at the given input. For example, you can give 1,000 images of a dog and 1,000 images of a table to a machine learning algorithm. Then, you will learn the difference between a dog and a table. When you give it a new image of a dog or a table, you can recognize which one it is.

You can apply the same idea to recommendation systems (think of YouTube, Amazon and Netflix), Face recognition or voice recognition among other applications.

Popular machine learning algorithms that you may have heard about include neural networks, deep learning, support vector machines, random forest … any of these algorithms can be used to solve the dog’s image tag problem and table.

Python for machine learning

There are known machine learning libraries and frameworks for Python. Two of the most popular are scikit-learn and TensorFlow.

Scikit-learn comes with some of the most popular machine learning algorithms incorporated.

TensorFlow is more a low-level library that allows you to create custom machine learning algorithms. If you are starting with a machine learning project, it is recommended that you start with scikit-learn. If you start to find efficiency problems, then you would start researching on TensorFlow.

Web Development: Django and Flash, for example, are Python-based web frameworks. These frameworks help create server code (backend code) in Python. That is the code that runs on your server, unlike users’ devices and browsers (front-end code). Here it is necessary to explain that a web framework is needed because it facilitates the creation of a common back-end logic. This includes correlating different URLs with Python code snippets, dealing with databases and generating HTML files that users see in their browsers. Django and Flask are two of the most popular Python web frameworks, more if you’re just starting.

Scripting: this refers to writing small programs that are normally designed to automate less complex tasks. Python is suitable for these types of tasks, mainly because it has a relatively simple syntax and is easy to write. It’s also quick to write something small with it and try it.

Ruby On Rails, An Option You Should Look At

To fully understand what it is, we must begin to explain that Rails is a development tool that gives web developers the possibility of a framework, providing a structure for all the code they generate. The Rails framework helps these people create applications and websites because it takes and simplifies the tasks that are repeated and that are common.

Rails are written in Ruby which is the programming language that is also used together with Rails. If you want some examples, Ruby is for Rails as PHP for Symfony and Zend, or as Python for Django. But what attracts Ruby’s developers the most is its elegance and simplicity of language.

Just to get an idea, Ruby on Rails is much more famous than you think, just to cite some of the famous cases, it should be said that Twitter was developed in the beginning with this web framework. GitHub itself is also developed with Ruby on Rails, a mandatory step for the publication of any open source development, also for computers that need to share code. Hulu, BaseCamp, SoundCloud. To this are added many companies and web applications that saw in the framework an excellent way of development.

Before starting to number the main benefits of this tool, we must be honest and also say some of the main problems it presents.

Not all web page hosts support Rails. Although it is true that not all servers support Rails, this usually occurs because more resources are required than PHP, something that discourages low-end shared hosting providers.

Performance and scalability. There are concerns that there are Raid applications that are not as fast as Java or C, and it may be true, but most Apps work fast enough.

Java and PHP are more popular, and there are more developers in these languages. The number of Ruby developers is growing year after year as more people switch to it from other programming languages.

Knowing some of the negatives, now the question to solve is why we should use Ruby on Rails

  • It is one of the 10 most demanded languages by companies and is one of the 20 most popular languages worldwide.
  • You have at your disposal a very active community committed to the quality of the code, as well as very good documentation.
  • Rails wants to make your life easier. Its philosophy is based on the Don’t Repeat Yourself (DRY) and the Convention on Configuration. The goal, do not repeat code over and over unnecessarily, nor worry about specifying every little detail through an endless number of configuration files.
  • It allows you to code what is specific to your app, leaving the other trivial things and configuration aspects in the hands of the framework itself. Ruby provides you with a workflow to perfectly structure your code.
  • The senior and junior profiles of Ruby on Rails are the most requested to work in startups and consolidated companies, in Spain and abroad. According to gooroo.io, the average salary for a Ruby developer is at more than $ 90K a year and is the fourth most demanded language on Angel List.
  • Because it is a free framework and with which you can write less code, the cost of developing an application can be greatly reduced.
  • Some of the most important websites today (AirBnB, Groupon, Hulu, SoundCloud, Twitter and GitHub) were developed with Ruby on Rails

4 More Benefits of Outsourcing to a Nearshore Development Team

4 More Reasons to use a Nearshore Development Team

If you are reading this article, you are probably a business owner or employee considering how outsourcing might affect your company’s return on investment. You might have already researched the differences between an offshore and a nearshore development company. We have already talked about the benefits of nearshore outsourcing in a previous post, but since there are so many potential gains from a nearshore company, we decided to highlight 4 more benefits below.

Setting up your own development team is a challenging task. This is why most of our clients have decided to rely on our experience; Kambda has pretty much become an external department they can always go to. They have also told us that one of the main concerns they faced before making their decision was “How am I going to let a third party manage such an important part of my business?”

We want to provide a list of benefits that will show you the benefits of hiring an external team can outweigh the issues you may encounter.

Quick Hands-On Development Work

As our current clients could tell you, if you require some development work we can start right away and right of the bat. We are able to quickly plan your project since we already have a team of experienced developers ready to work on your project. We also have different skillsets, which means we can support you in different areas, languages or projects.

If you plan to work in-house, setting up the right team for your project could potentially take months. You would have to make sure you have the right physical space, acquire software and hardware, find the right people, hire them, and solve many other challenges along the way. It could already be too late to execute a time-sensitive project by the time you set up your team.

Seamless Team Management and Growth

With a nearshore development company, you have the chance to provide support to your in-house team as required. If you were planning to grow your team, you would have to spend at least 2 to 3 weeks in finding the right people even before any project planning takes place. Additionally, your new hires would require some more onboarding time learning about your company and the project itself.

A nearshore team is already built and ready to go if your in-house team requires back up. Not only that, but you can grow it as much as you can without the hassle of hiring new team members directly. We do it all for you!

A Wider Range of Technologies

With an in-house team, you are required to work with the skillsets and technology expectations your team has experience with. If you require work in a different field, you would have to spend significantly more time and resources in training and learning or hiring an additional resource with this skillset, even if you don’t have enough work to fill up its time.

Nearshore development companies, on the other hand, have been exposed to different skills and technologies due to their nature. This means they have more experience on broader scope of work. A team like this can help you fill in the gaps so you get high-quality work on time and in-budget.

Also, nearshore agile development teams can use their experience to help you avoid common development and design issues, increasing efficiency.

High Adaptability to your Business

Developing software is not only about coding, it also requires an almost perfect understanding of the business side and building a bridge between it and the technical aspects of the company.

An experienced outsourcing team will have already built positions, methodologies, and processes to help them fall in place, almost perfectly, with the requirements, and business side of a company. This is ideal to help kick-start a process efficiently tackling issues with higher precision, less churn and waste.

A nearshore team will apply any knowledge or skill acquired in a project to the next. Providing greater value while shortening the time it takes to adapt and learn when getting started with a new company.

Why is React Native App Development worth it?

Why is React Native App Development worth it?

The Future of Mobile App Development with React Native

React Native app development is highly known for making the lives of UI developers easier; it is built to create apps that can be used in both Android and iOS with the same codebase.

React appeared to change our perception of how we create apps, it was then accompanied by React Native, and both were available to develop mobile apps for both operating systems. Since it was initially meant to work on mobile platforms, it now maintains core elements that make it feel more like web development; JavaScript, JSX, and Flexbox. Finally, react-native-web was engineered to enable React Native developers to take their apps and put them back on browsers.

Interest in React Native is stronger now than ever. This makes it a robust framework to take into account when assessing some mobile app development solutions. Companies like Pinterest, Skype, Tesla, Uber, and many more have relied on it to build their cross-platform mobile presence.

It is understandable to want to avoid things learning technologies that might die off in the future but React Native is not one of those. Increasingly, more and more developers are learning and implementing this promising framework.

Some of React Native’s Current Limitations

Since it is a relatively new framework, React Native’s available documentation is still not highly comprehensive. Even though Facebook and the React community are putting an effort, there are some React Native components that are not well covered in the documentation available. Due to the same issue, how recent it is, many main elements seem to still be a work in progress, and some of the code’s quality might be disappointing.

You can use third-party components, but their numbers are really limited when compared to other libraries created by the community for iOS or Android. Additionally, compatibility and support are not guaranteed for these components.

As you see, most of React Native’s limitations can be solved in the future, once the framework is even more widely used and experimented with by the community. Since interest on it is still evident, it makes sense to think that most of these issues will be solved in the coming years.

Why Choose React Native to build your Application

Yesterday, creating universal apps was a thing of dreams; today, that dream has come true. Though it is an ideal option for cross-platform mobile app development, there are many things to consider around using React Native. Even if it sounds similar, React Native is not equal to Titanium or Cordova as it was created, since it keeps the differences between platforms in mind. Its crucial goal is to harness the best things about React libraries, which work wonders in the web and bring them to the native mobile apps without having to hire different teams of developers for each system.

React Native embeds JS files in the app and runs them locally, making run-times smoother. Additionally, you could make the app fetch remote data when connectivity is available; which results in a quick way of updating an application, evading the App Store’s complex validation process.

This framework is mostly built based on JavaScript and the Paradigms of React. This is why it makes sense to have a React Native mobile development team mainly composed of JS engineers as, hopefully, they will already be knowledgeable in the paradigms running the framework, like React, EcmaScript, Flex layout, and Redux.

Creating a mobile app in React Native is worth it, as it can be used as one single language to create the UI of the different versions of an app. Also, it is a framework with a bright future in front of it; it is backed by a thriving community who has set long-term plans for it. React Native has been transforming the way we create exciting new apps with the practicality of cutting down your expenses and execution time. Try it now, talk to a React Native specialist!

NOC: How It Can Help You With Your Infrastructure

NOC: How It Can Help You With Your Infrastructure

By: perfilestecnologicos.com

What is NOC?

It stands for Network Operations Center, and it is an operations center for network infrastructure, which constantly monitors networks, as well as their designated devices. This is done in order to maintain network and servers in optimal condition. Engineers specialized in network equipment, servers and security applications monitor data, solve issues, update information, and implement continuous improvement.

An operation center with network infrastructure has multiple levels to classify specialists according to the category of service:

  • Level 1
  • Level 2
  • Level 3

Therefore, some issues are escalated within the NOC, previous to contacting an engineer or field specialists.

And why outsourcing this type of service? As stated by Nap It Global Network Solutions (“¿Por qué tercerizar…?,” 2018) the current corporate scenario is very different from the one we experienced some years ago. The processes make use of files in the cloud and complex software, making the development of the company directly connected to the proper performance of the network.

This is when the NOC becomes relevant, given that through this active monitoring service, it is possible to identify and solve issues before they occur, which allows for more security for your network and internal processes. Because the NOC is composed by a series of tools and specific processes, the creation of a specific, own area in the company for this purpose may represent a high investment. Furthermore, there are few professionals in the market with experience and the appropriate requirements to run this type of analysis, making the outsourcing of this service an option of a lower cost and higher service quality (“¿Por qué tercerizar…?,” 2018).
