Backend-leaning full-stack engineer in Ho Chi Minh City, and co-founder of EyesZ, where I lead engineering. Open to remote roles and contract work.
Building: iZe Edu — multi-tenant SaaS for preschools, private schools and skill centers (private repo, happy to walk through it):
- Python 3.12 / FastAPI modular monolith (clean architecture) · Next.js 15 PWA · PostgreSQL 16 · Redis + Celery outbox worker · Turborepo/pnpm + uv monorepo · Flyway migrations.
- Conflict-free timetabling enforced in the database (PostgreSQL exclusion constraints).
- Attendance by rotating 30-second TOTP QR codes and a face-recognition kiosk with liveness checks (ONNX Runtime).
- Tuition invoices with VietQR (NAPAS 247) and automatic payment reconciliation from bank webhooks.
- Student health records protected with AES-256-GCM envelope encryption.
Before
- Full Stack Developer @ INTRATECH JSC (06/2025 – 07/2026): IPO Ready (50+ REST endpoints, Celery pipeline for 10,000+ records, −95% Docker build time) · Ca Heo laundry chain platform.
- Software Engineering, Ho Chi Minh City University of Technology — GPA 3.31/4.0, Outstanding Student Award 2023–24 and 2024–25.
How I work: spec → architecture → stories → TDD → independent review, with AI coding agents doing the typing and me owning the design and the review.
