I build backend services in Go with clean architecture, correctness, and performance as first-class concerns — systems that stay simple as they grow and hold up under load.

AzureNights2 — a moddable terminal-game engine in Go, built as an architecture showcase
Hexagonal design with a pure, I/O-free domain core and pluggable adapters — a terminal UI and file storage today, with an HTTP server that drops in over the same ports. Content is data-driven (JSON + go:embed, validated at load), tests run under -race, and CI/CD with cross-platform release builds has been in place from the start.

Concurrent ingestion and integration pipelines that keep downstream clients fed with clean, fresh data.

Before engineering full-time, I shipped real products end-to-end — a live iOS app (GlassMind, on the App Store) and an Unreal mobile game built under hard frame and memory budgets.

Earlier, I served as a UAV unit commander in the Armed Forces, where latency, fault tolerance, and reliability weren't features — they were the line between mission success and failure, with no room for error. That's the mindset I bring to backend systems.
