Trung thành Trần

At Madalena, I built and shipped a customer loyalty app to the App Store and Google Play as the only developer. It connects a React Native app with a PHP API and supports points, rewards, QR check-in, and scheduled notifications.

I also built an Electron admin for staff and most features of the company’s PHP e-commerce site, linking products and sales data to the app. I moved the backend from Node.js on Render to PHP hosting and added automated backups and brute-force protection.

My open-source project supabase-rls-check is a read-only catalog query and CLI that flags eight types of Supabase and Postgres security misconfiguration. Its CI checks PostgreSQL 15 against seeded issues, and the project includes 52 tests and a reviewable fix script.

In freelance work, I delivered an architecture report for a job-posting bot and built a fitness web app with live exercise form feedback and a food photo classifier. I’m open to remote contract work for about 20–30 hours per week, working asynchronously and in writing.
