Project Management

Writing multiple native applications for different mobile platforms can be a daunting task, but taking a non-native approach comes with pitfalls of its own. In this article, Toptal Mobile Developer Joel Frank outlines the concept of Write Once, Deploy Everywhere (WODE) and explains how to choose the right development path for your project.

The quietly growing number of serious Haxe projects have something new to contend with: the first major compiler release in over three years. What does Haxe 4 bring to the table?

While Redux is a great state management solution, it doesn’t support asynchronous behavior by default. A way around this is to use redux-observable, based on RxJS - a powerful library for reactive programming in JavaScript.

Unwanted AI bias is already a widespread problem. Machine learning models can replicate or exacerbate existing biases, often in ways that are not detected until release. So what can be done about it?

For a successful natural language processing project, collecting and preparing data, building resilient pipelines, and getting "model ready" can easily take months of effort even with the most talented engineers. But what if we could reduce the data required to a fraction? In this article, we’ll cover how transfer learning is making world-class models open source and introduce BERT (bidirectional encoder representations from transformers). BERT is the most powerful NLP “tool” to date. We’ll explore how it works and why it will change the way companies execute NLP projects.

Nearly every app requires an authorization system on top of an authentication system. We often need a fine-grained permissions model to allow only specific users to access certain resources while simultaneously restricting access for everyone else. In this tutorial, Toptal Freelance Firebase Developer Joaquin Cid teaches how to build just such a system. Called a role-based authentication, we’ll learn how to implement this system in an API using Node.js and Firebase.

Subscription-based apps need a special approach when it comes to analytics. Learn how a variation on the traditional sales funnel helps you work with LTV, subscriber retention, and churn rates to make your app better—and more profitable.

Building a mobile app isn't cheap—and the harsh reality is that most apps fail. Find out how to leverage fundamental analytics metrics to make sure your app actually turns a profit.
