OBJECTIVE

Final-year Software Engineering student at HUTECH (coursework completed, graduation certificate pending), with hands-on experience building end-to-end web applications using ASP.NET Core (.NET 8), Node.js/React, and FastAPI. Comfortable doing independent technical research and deep debugging — including tracking down a real-time race condition down to the database transaction level. Looking for a Full-stack or Backend Developer role to work on production-grade systems and grow further as a developer.

• Have integrated VNPAY payment gateway and Gemini API into a project before, plus Google OAuth 2.0 for login

Backend Developer Intern 05/2026 – 07/2026

SmartHealth – AI-powered Health Management System

• Wrote APIs in FastAPI on top of an existing codebase, so most of the work was reading, fixing, and re-testing against PostgreSQL/SQLAlchemy

• Handled Google login (OAuth 2.0) and the user profile module, documented the API with Swagger so the frontend team could work off it easily

Full-stack Developer 03/2026 – 04/2026

Real-time Online Auction System — Coursework Project

• Handled the whole stack solo: Node.js/Express backend, React (Vite) + Tailwind frontend, for a real-time bidding site

• Used MongoDB for storage and Socket.io so everyone watching could see bid updates live

• Ran into a bug where simultaneous bids threw off the final amount — turned out to be a race condition, fixed it by locking the transaction

Full-stack Developer 09/2025 – 12/2025

Spa Management & Booking System — Capstone Project

• Built both the frontend (Razor/Bootstrap) and backend (C#, .NET 8, Entity Framework Core) for a spa booking system

• Designed the SQL Server schema myself and wrote the logic for bookings, customer records, and revenue reports

• Added VNPAY for online payment and Gemini API for a Q&A chatbot. The two ended up conflicting during testing, took a while to trace it back to a shared session issue

• Source code: github.com/thienlac123/spa_booking
