Platform infrastructure engineer specializing in safe AI automation for revenue-critical legacy systems. I design, build, and operate production systems end to end — a multi-portal PHP / MySQL reservations platform, multi-tenant AI assistants on Docker, a Python agent-orchestration host, and an internal FastAPI / Next.js platform to replace a SaaS vendor — the stack a multi-million-dollar specialty-travel business runs on.
Most of that work lives in private repositories. The architecture and the reasoning behind it are written up in the ETA Platform case study and in infrastructure-patterns (sanitized ADRs).
I also contribute upstream - recently a MySQL 8.4 caching_sha2_password auth-handshake fix to php-mysql-replication.
Outside work I ship cross-platform apps with a privacy-first bent - client-side encryption, offline-first storage, and one core driving many native shells. A few are pinned below.
