Senior Software Engineer building web, mobile, and backend systems. 5+ years shipping full-stack products — payments infrastructure, AI search pipelines, multi-tenant SaaS, and offline-first mobile apps.
I'm currently at xFarm Technologies, building cross-platform Flutter apps for a farm management platform serving 600,000+ farms across 14M+ hectares.
Previously at Breakthrough, I owned the backend platform powering a white-label wellness app used by 130+ partner creators — Stripe billing on AWS ECS, AI semantic search on Vertex AI, and a Next.js paywall serving 60+ brands from one codebase. Before that, PixelApps and Pingolearn.
On the side I build open source — most recently pglens, a PostgreSQL viewer, and Wallbay, a Flutter wallpaper app with 114+ stars on GitHub.
