Project Management

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.

DevOps is an oft-misunderstood buzzword, seen as a trendy must-have in the form of technologies, tools, and staff to acquire. But it's much more, yet much simpler, than that.

You can just write sequentially executed code in JavaScript, but should you? In this article, Toptal Freelance JavaScript Developer Omar Waleed tests the widespread Node.js belief that synchronous code degrades performance and is, in a sense, just plain evil. Is this really true?

When complex systems are life-critical, it can be extremely difficult to modernize and upgrade them safely. While many engineers will never work on such systems, there is much to be learned from those who do. In this article, Toptal Solutions Architect Dr. Kyle Kotowick explains how to properly maintain and update systems that are too important to fail.
