Roberto Pillitteri.
Software Engineer III.
Site Reliability Engineering
I keep large-scale distributed systems reliable by day, and write low-level systems software for the love of it. Sicilian based in Warsaw.
// about
A polymath who refuses to stop digging.
I fell in love with programming at 13, and that early obsession with how machines work at the lowest level never left me. I write C from first principles, for the joy of understanding things end to end.
I hold a master's in Computer Engineering from the University of Catania and have over five years in the field. I worked as a Tech Lead and Architect earning 12+ certifications including Application Architect and System Architect before moving into Site Reliability Engineering at Google.
I care about performance and code that is both correct and elegant. I also focus heavily on AI. I'll soon be starting a PhD in AI. I have a polymath streak and a healthy backlog of side projects.

Built to understand, not just to ship.
gemma3.c
A complete inference engine for Google's Gemma 3, written in pure C11 with zero external dependencies. A from-scratch implementation of modern LLM inference — built to understand transformers down to the metal.
LightCosmosRat
Project I developed when I was still a student. Remote Administration Tool for Windows written in C# and that back at its time was undetectable.

Want to talk distributed systems, C, or AI?
I'm always up for a conversation about reliability, compilers, the right way to write a hot loop, or whether the Toy Story aliens deserve their own film.
