About

I work across mobile, full-stack and AI systems, with a strong focus on architecture, backend engineering and high-performance solutions.

I enjoy building things from scratch — network servers, parsers, CLI tools — and I care about the low-level details: memory management, concurrency, I/O protocols and performance tuning.
