What I'm looking for

I’m looking for a team where I can build and modernize reliable .NET microservices, own end-to-end delivery (frontend + backend when needed), and keep quality high with strong test coverage—using AI-assisted development to ship faster without cutting corners.

I’m a Senior .NET developer with 10+ years delivering mission-critical systems across government, SaaS, and enterprise platforms. At Singapore’s national tax authority (IRAS), I’m building microservices serving 6 million residents, with a consistent focus on reliability, maintainability, and high test coverage.

Recently, I diagnosed and fully restored a broken batch recovery flow, restoring re-execution reliability to 100%, and improved batch performance from over 9 hours to 4 hours for 300K+ records. I’ve also delivered features under deadline pressure, built end-to-end micro frontend capabilities, used AI-assisted tools (GitHub Copilot, Claude, PairAI) daily, and maintained 80%+ unit test coverage while exceeding SonarQube quality gates.
