Selected work

Projects built end-to-end — from database design to production deployment.

01

Pacific Travel

Fullstack Travel Booking Platform

Full-stack tour booking platform with JWT auth, Redis caching, and payment gateway integration. Deployed to DigitalOcean VPS via Docker, Nginx, and GitHub Actions CI/CD. Integrated Google Gemini API for AI-powered travel recommendations.

45% faster page load after SQL optimization and PostgreSQL + Supabase migration. Demonstrates end-to-end ownership from API design to production deployment.

02

BookStore

Ecommerce Platform + Admin Workflow

Full CRUD web app for book and order management with ReactJS frontend and Spring Boot backend. Integrated Keycloak for role-based access control and Camunda workflow engine for automated order processing.

Demonstrates ability to build both customer-facing storefront and internal admin tools within an enterprise-grade auth and workflow setup.

03

ACB Bank E-Form System

Enterprise Banking — Production Internship

Maintained mission-critical digital banking e-form systems for ACB Bank on-site during a 9-month internship at FPT IS. Performed bug fixes, functional and regression testing, code reviews, and security patches under strict enterprise banking standards.

Production-level exposure to high-stakes financial systems. Applied enterprise security practices alongside senior developers and QA in a regulated banking environment.

How I work

A simple workflow for how I approach product and engineering work.

This section is about how I work, not how the portfolio is built. It shows the way I usually move from understanding a problem to shipping something reliable.

Step 01

Understand the problem

Clarify the product goal, technical constraints, and the real problem that needs to be solved before designing anything.

Step 02

Design the system

Shape the API flow, data model, service boundaries, and delivery plan so implementation has a clear direction.

Step 03

Build end-to-end

Implement the backend, connect the frontend, and make sure the product works as a complete system rather than isolated pieces.

Step 04

Test and refine

Review edge cases, improve reliability, and polish the final result so it is practical enough to ship and maintain.

Engineering focus

Backend-first thinking, fullstack delivery.

I focus on the parts that make software actually work — secure auth flows, reliable APIs, and deployment pipelines that don't break. The frontend is there to serve clarity and usability, not the other way around.

I build production-ready APIs with Spring Boot, handling auth (JWT, Keycloak), data modeling, and service boundaries that can scale with the product.

Frontend work is driven by user flow and business goals — ReactJS for interaction, Tailwind for speed, and component structure that stays maintainable.

I've worked in real production environments: ACB Bank e-form systems, Docker-based deployments, GitHub Actions CI/CD, and DigitalOcean VPS.

Next pass

Open to Junior Fullstack or Backend roles in Ho Chi Minh City.

I'm actively looking for a team where I can contribute from day one — whether that's building APIs, maintaining systems, or shipping features end-to-end. Feel free to reach out via email or connect on LinkedIn.
