About

Idea → application → API → data → payment → production.

Fullstack developer with 3+ years of web development — frontend-focused, now leading backend — and 3 years teaching programming to kids. I build SaaS platforms end-to-end: React, Next.js and Flutter interfaces on top of Node.js and Supabase APIs, databases and third-party integrations like Stripe, Zalo and AI services.

01 — Application

It starts on a screen.

Customer and stylist apps in Flutter, admin dashboards in React and Next.js — booking, orders and inventory flows designed around the user's task.

02 — API & data

Behind it, a system.

REST APIs on Express and Fastify, MongoDB and PostgreSQL, Redis/Bull job queues and Socket.IO real-time — built for multi-tenant SaaS.

03 — Payments & integrations

Money and data move safely.

Stripe subscriptions and webhooks, NextPay and VietQR, plus Zalo Mini App/OA/ZNS, Ahamove, VietMap and AI services wired into real workflows.

04 — Production

Then it ships.

Docker, Nginx and Ubuntu VPS, Supabase Edge Functions and AWS S3 — deployments that keep running after launch day.
