About

Shipping reliable systems, end to end.

I'm a Software Engineer with 3+ years of experience building and shipping production web applications. My core stack is Java / Spring Boot on the backend and React / TypeScript on the frontend, integrated through well-designed RESTful APIs.

I care deeply about system correctness, measurable performance, and clean architecture. I've worked across the full delivery lifecycle — from stakeholder requirements through schema design, API development, CI/CD, and cloud deployment on AWS.

Based in Singapore. Currently open to full-time opportunities.

Backend-first engineering
