Back-end

Uploading a video to YouTube seems like a simple enough task, but non-existent documentation and unmaintained libraries can make even the simplest of tasks seem daunting.

In this post, Toptal Freelance Django Developer Ivan Carmo da Rocha Neto guides you through how to post YouTube videos from your Django app.

Moving to a microservices architecture often raises the question: What is the best environment to stabilize services? Here’s how and why you should use Kubernetes, Docker, and CircleCI to containerize and deploy apps.

Angular 6 is out! The most outstanding changes are in its CLI and how services get injected. In this tutorial, Toptal Freelance Angular Developer Joaquin Cid goes over the basic steps of initial setup and then creates a small diary app using Material Design for the front end and Firebase for the back end.

The Ethereum Name Service is a blockchain-backed alternative to the internet’s traditional Domain Name System. If you own a .eth domain, you can deploy smart contracts that let users set up their own subdomains—but then, of course, you’ll want a corresponding ĐApp to make it user-friendly. In this tutorial, Toptal Freelance Ethereum Developer Radek Ostrowski provides complete coverage of this scenario, this time with a focus on ĐApp development.

Static websites offer a host of advantages over dynamic pages in many scenarios, but they can be impractical and tedious to maintain.

In this, Toptal Front-end Developer Silvestar Bistrovic demonstrates how the four most popular static page generators can help.

Leveraging DeepMind’s breakthrough AI approaches takes some work, but the results are astounding. In this article, Toptal Freelance Deep Learning Engineer Neven Pičuljan guides us through the building blocks of reinforcement learning, training a neural network to play Flappy Bird using the PyTorch framework.

In this article, Toptal Freelance JavaScript Developer Nick Chikovani shows how easy it is to perform web scraping using a headless browser. Specifically, he provides a Puppeteer tutorial, going through a few examples of how to control Google Chrome to take screenshots and gather structured data.

How do you approach machine learning problems? Are neural networks the answer to nearly every challenge you may encounter?

In this article, Toptal Freelance Python Developer Peter Hussami explains the basic approach to machine learning problems and points out where neural may fall short.

ASP.NET Core is a leaner and more modular redesign of ASP.NET 4.x.

In this article, Toptal Freelance ASP.NET Developer Damir Imangulov shows how to build a robust RESTful API using ASP.NET, EF Core, AutoMapper, and XUnit.

Microsoft and Google have worked together since Angular 2, rendering ASP.NET Web Forms and MVC Razor obsolete. Nevertheless, while ASP.NET’s front-end tools may be lacking, it is still a great back-end framework.

In this article, Toptal Freelance Angular Developer Pablo Albella teaches us how to create the best architecture for both these worlds.

JSON web tokens (JWTs) provide a method of authenticating requests that’s convenient, compact, and secure. More often than not, Angular apps will include them in their data flows.

In this tutorial, Toptal Freelance Software Engineer Sebastian Schocke shows how to implement JWT authentication in an Angular 6 single-page application (SPA), complete with a Node.js back-end.

The modern, cross-platform programming language Haxe is well-known in some circles, yet many developers have never heard of it. Since it first appeared in 2005, it’s been battle-tested by its loyal—if rather quiet—following.

In this article, Toptal Freelance Software Engineer Kevin Bloch explores the Haxe ecosystem and how to transpile some sample code.

The microservices architectural pattern is an architectural style that is growing in popularity, given its flexibility and resilience.

In this article, Toptal Freelance Python Developer Guilherme Caminha will focus on building a proof of concept microservices application in Python using Nameko, a microservices framework.

Threading is just one of the many ways concurrent programs can be built. In this article, we will take a look at threading and a couple of other strategies for building concurrent programs in Python, as well as discuss how each is suitable in different scenarios.

Do you run deployment scripts from your development machine, or find yourself referring to deployments by the day of the week they were deployed, instead of using version numbers? It’s time for a better solution.

In this article, Freelance Ruby Engineer and automation enthusiast Amin Shah Gilani walks you through his perfect deployment pipeline to use at the beginning of your project. With this CI/CD configuration, every push is tested, the master branch is deployed to staging servers with a fresh database dump from the production server, and versioned tags are deployed to production with backups and migrations running automatically.

Rails ships with everything you need to prototype your application quickly, but when your codebase starts growing, you’ll run into scenarios where the conventional Fat Model, Skinny Controller mantra breaks. When your business logic can’t fit in either a model or a controller, that’s when service objects come in and let us separate every business action into its own Ruby object.
