Hello, I'm Lajos

I write software.
Sometimes I figure out why it broke.

I'm a software engineer based in Hungary. I've spent most of the last decade working with distributed systems, RabbitMQ, Erlang and production infrastructure. Lately, I've been exploring AI infrastructure with a Rust side project called LATOR.

What I do

Mostly backend and infrastructure.

I like digging into how systems behave when they're busy, slow, or failing. A lot of my work has involved debugging production issues, performance investigations, integrations and making distributed services easier to operate.

✳

Lajos's AI Tracer & Router. I'm building an OpenAI-compatible gateway in Rust to learn more about inference infrastructure. The idea is to route model requests, capture what happened, replay them and compare performance across providers.
