I'm Carlos Tosta, a Backend & ML Infrastructure Engineer from Rio de Janeiro with 15+ years of experience building software that scales. My work spans backend architecture, infrastructure automation, and AI-powered processing pipelines. My current focus is taking systems and models from prototype to production, mostly in Python, Rust and TypeScript, while optimizing GPU usage with queue solutions.
I enjoy automating everything I can — from deployment pipelines to game dev — and I'm always looking for ways to make complex systems simpler and more reliable. When I'm not writing code, you'll probably find me refining a game mechanic, experimenting with retro visuals, or optimizing a container build.
This blog is where I share ideas, experiments, and tools I've built along the way.
