## Summary

Computer Science graduate from the National University of Singapore (GPA 4.56 / 5.0, Distinction) with software engineering experience across internships, part-time work and client projects since 2020. I build full-stack web applications end to end, from database design and secure backends (PostgreSQL, Supabase Row-Level Security, role-based access control) to React and Next.js frontends, and I deploy them with Docker, AWS (ECS, ECR, Lambda), Terraform and GitHub Actions CI/CD.

Recent work includes a 13-module ERP platform of over 50k lines of code that doubled an SME's administration efficiency, a privacy-first personal finance application built in partnership with AIA, and a nationwide smart locker tracking portal serving Shopee, Lazada and Amazon. I started out in infocomm security (Singapore Polytechnic diploma, SAF Signals, a penetration testing final year project), so I treat security and data integrity as defaults. At NUS I also served as President of a student organisation with over 300 members.
