## About

GulfCoast Dev is the studio of Janusz Chudzynski — a senior engineer who has spent 10+ years shipping Apple-platform software used by millions.

Over my career I've delivered software for private clients, state institutions, military organizations including the United States Navy, and large commercial companies. Most recently I worked on Camtasia for Mac at TechSmith, modernizing legacy code, shipping user-facing features, and researching AI/LLM integration in a native desktop app — so I bring production-grade craft to every engagement, not just working code.

Today I run my own products under GulfCoast Dev LLC, which means I understand what it takes to own something end-to-end: the architecture, the UX, the release, and everything that breaks after launch. If you need a senior Apple engineer who can lead the work and hand you something maintainable, that's exactly what I do.
