Experience

  • Hunting and Analyzing High CPU Usage in .NET Applications (Publication)
    https://www.toptal.com/dot-net/hunting-high-cpu-usage-in-dot-net
    Software performance in production is hard to analyze. Things can go wrong at any time, and code can start executing in ways that weren’t planned for. In these cases, what do we do? In this article, Toptal engineer Juan Pablo Scida analyzes a real scenario of high CPU usage of a web application. He covers all the processes and .NET code analysis involved to identify the problem, explains how the problem was solved, and most importantly, explores why this problem happened in the first place.
  • Software Reengineering: From Spaghetti to Clean Design (Publication)
    https://www.toptal.com/nodejs/software-reengineering
    Inheriting someone else’s code can be a nightmare, especially when the code is poorly designed and lacks documentation. In this post, Toptal Engineer Juan Pablo Scida provides a case study of how he reengineered a chat server written in Node.js, transforming its original spaghetti code into a cleanly architected and designed piece of software.
