Who I am

About Me

I'm Petar Petrushev, a self-driven full stack developer and systems engineer passionate about building things that actually work at scale. From architecting enterprise email infrastructure to crafting polished front-ends and harnessing the latest AI models, I enjoy owning the full stack from end to end.

My approach combines deep technical expertise with a product mindset to build complete solutions. Whether it's a resilient mail server cluster, a client-facing web platform, or an intelligent AI router, everything is built to be reliable, performant, and maintainable.

I'm passionate about automation, smart development, and getting the maximum performance out of hardware and software.
