Harnessing the potential of machine learning for computer vision is not a new concept but recent advances and the availability of new tools and datasets have made it more accessible to developers. In this article, Toptal Software Developer Teimur Gasanov demonstrates how you can create an app capable of identifying handwritten digits in under 30 minutes, including the API and UI.

Extracting functional components from a monolithic app into a service can be a daunting task but choosing the right tools and techniques for the job can expedite the process. In this article, Toptal Back-end Engineer Maciek Rzasa recounts how his team extracted billing functionality from the Toptal platform and how they overcame a series of performance issues.

Software development is a complex process and evaluating the performance of software engineers can be too. It is important that you find the right balance between that complexity and practicality in software engineer performance reviews. In this article, Toptal Engineering Blog Editor Nermin Hajdarbegovic outlines the difference between commonly used performance review models and discusses how they should be employed.

WebAssembly gives near-native performance to web apps and allows languages other than JavaScript—plus their libraries—to be used on the web. This tutorial leverages Rust and the Web Audio API to make a basic guitar tuner app that runs at 60 FPS, even on mobile.

The Apple M1 processor represents a significant step forward for Apple, but what does it mean for developers, designers, and other professionals using Apple hardware? In this article, Toptal Engineering Blog Editor Nermin Hajdarbegovic outlines what makes the M1 different and what professionals need to keep in mind should they choose to upgrade their hardware.

Time and date manipulation is notoriously difficult. Developers encountering time zone rules, leap seconds, differences in locale-specific formatting are wise to resort to popular time and date manipulation libraries. But without thinking about how exactly they work, it's still easy to create all sorts of obscure bugs.

Git provides basic branching operations, but advanced patterns are left up to the user. The popular "Git flow" branching model helps, but can also complicate some common procedures. Thankfully, a new variation retains the benefits, while streamlining everyday work.

The release of Vue 3 brought about substantial performance improvements, but they should not overshadow the introduction of new features and paradigms. In this article, Toptal Full-stack Developer Luka Mikec introduces you to the new Composition API and explains what Vue 3 means for code expressiveness, organization, and reuse.
