/ projects

Some projects I've worked on.

I built a lot :Đ.

Full-stack support platform

Support Dashboard

deployed

A customer support ticketing system with JWT authentication, role-based access control, ticket lifecycle rules, replies, and assignment workflows.

SUPPORT_DASHBOARD.GIF

why it exists

Built to practice designing real full-stack application logic, not just static frontend screens.

core work

JWT auth with customer, agent, and admin roles
Ticket state machine with invalid transition protection
Role-based permissions for replies, assignment, and status updates
PostgreSQL-backed backend with production-style Docker deployment

$ role

operating pattern

I prefer building from the inside out: data model, API behavior, permission rules, failure cases, deployment shape, then UI. The goal is not just a nice screen — it is a system that can survive real usage.

/ about

More about me.

I play guitar, TFT and listen to PKLinh's music.

I'm trying every day to become a better developer and a better person. I like learning new things, building projects, and connecting with people. I want to work on projects with real users and real problems, while continuing to improve my skills and the way I think.

Profile

verified by myself :)

Fast learner

I can pick up new tools, codebases, and workflows quickly. When I do not know something, I break it down, test it, and learn by building.

Adaptable teammate

I am comfortable adjusting to different tasks, feedback, and team styles. I try to stay calm, ask better questions, and keep moving forward.

Clear communicator

I can explain what I am doing, what is blocked, and what I need. I also use English comfortably for documentation, technical reading, and team communication.
