What I'm looking for

I seek product‑focused engineering roles where I can build reliable, scalable systems, collaborate with cross‑functional teams, and drive measurable user and operational improvements.

I am a full‑stack software engineer experienced in building scalable web applications and backend systems using React, Next.js, Node/NestJS, and Go. I have driven product growth and reliability—launching an AI perks platform to 3,000+ active users, designing Supabase schemas to handle 7.5x user growth, and implementing microservices communication with gRPC for financial transaction processing.

My work emphasizes engineering quality and measurable outcomes: migrating component libraries to reduce duplication, increasing test coverage with 100+ unit tests, improving uptime and reducing recurring errors through DevOps collaboration, and implementing fault‑tolerant distributed systems (Raft) that achieved 99.9% uptime under failure injection. I thrive on building robust systems that improve user engagement and operational stability.
