Hi, I'm Trong Pham Tran Duc.I build thoughtful web products.

Building the internal rewards platform that powers airdrops, tier programs and reward campaigns across multiple games. Owning vertical slices from PostgreSQL schema and Go services to the Next.js admin and live analytics.

Full-cycle work for SMEs and startups, from business consulting through to production: a property CRM, a boarding-house management SaaS, dealer ordering, clinic admin and accounting systems. A lot of it lives in the Zalo developer ecosystem — Mini Apps, ZNS and API integrations — because that is where Vietnamese customers already are.

Built a multi-role admin web app for a clinic group — doctors, editors and marketing share the same publishing flow with an approval queue and an audit log tuned for medical compliance.

Led a small team building a Payload-based CMS and the public academy site. Designed the content model, the editor block library and the role-based publishing workflow that lets non-engineers ship a course on their own.

Designed and teach the advanced backend curriculum — Node.js, PHP and RESTful APIs. Mentoring students through real-world architecture, cloud deployment and performance work, and co-author of the technical material shared across the training programs.

Shipped a React Native community app for a Vietnamese real-estate startup. Designed the offline-friendly chat layer and the listing capture flow tuned for flaky 4G — plus the Node/MongoDB backend behind both.

Led backend design for the internal platforms — WORKPLACE and the in-house CRM — used by 3,000+ colleagues with 2,000+ concurrent sessions at peak, and for the sales channels reaching over a million customers. Improved throughput and cut latency more than tenfold with caching and query work, took 50% off operating cost with automation, a chatbot and in-house ZNS and email services, and cut manual deploy time by 70% with a CI/CD transformation.

Coached teams through full-stack projects on the MEAN and MERN stacks, led Web3 and blockchain R&D with Solidity and NestJS microservices, shipped Flutter mobile work and guided app-store publishing, and ran seminars on architecture, testing and CI/CD.
