How I work

How I approach product and engineering work.

From understanding the problem to shipping a reliable product.

Step 01

Understand the problem

Clarify goals, constraints, and the real problem before coding.

Step 02

Design the system

Define API flow, data model, and service boundaries.

Step 03

Build end-to-end

Implement backend and frontend as one complete system.

Step 04

Test and refine

Handle edge cases, improve reliability, and polish delivery.

Engineering focus

Backend-first thinking, fullstack delivery.

I focus on the parts that make software dependable in production: secure auth flows, reliable APIs, and deployment pipelines that stay stable under change. Frontend decisions still follow user flow and business outcomes.

Build production-ready Spring Boot APIs with JWT/Keycloak, clear service boundaries, and data models designed for long-term maintainability.

Use ReactJS + Tailwind to keep the frontend fast to iterate while staying aligned with real user journeys and product goals.

Hands-on production experience in banking systems, Docker-based deployments, and GitHub Actions CI/CD across real delivery cycles.

Next pass

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

I'm looking for a team where I can contribute from day one in backend or fullstack delivery. Reach out via email or LinkedIn.
