03 / About

Clarity in the code.
Care in the details.

I am a full-stack software engineer with hands-on experience delivering backend APIs, frontend features, and operational tooling in production environments.

My work focuses on reliability, data quality, and delivery speed. I use AI-assisted development tools including OpenAI Codex and GitHub Copilot to explore solutions, accelerate implementation, and improve documentation and tests, while keeping engineering judgement, review, and verification at the centre. I enjoy turning recurring operational problems into well-tested software, investigating production issues, and working closely with developers and stakeholders to ship practical improvements.
