Rockstar🎓
Top SchoolAntonio Di Stefano is a software developer based in London with a decade of experience building backend systems and developer tooling across startups and larger platforms like eBay and Soldo. Currently at EngFlow, he combines practical product delivery with deep familiarity in build systems—Bazel and remote build execution are a notable interest from his GitHub notes. His open-source contributions include substantive work on the Natalie Ruby compiler, implementing core Array behaviors, optimizations for integers, and improved hashing—evidence of low-level language and performance expertise. Antonio blends hands-on C++/Ruby systems work with Java backend experience and a pragmatic product mindset honed through roles ranging from intern to internal demand manager. He’s the kind of engineer who can both tune compiler internals and ship reliable backend features in production.

In-utils is a set of standard javascript utilities with a twist, an horrible one. They're made to be as slow as humanly possible, but still completely idempotent and deterministic
