Software Engineer
Turning complex engineering problems into systems that run smoothly.
I'm a software engineer based in Nghe An, Vietnam, with a year of hands-on experience building web applications from database to interface. I enjoy breaking down complicated technical requirements into clean, maintainable systems, and I care deeply about code quality, clear architecture, and shipping features that make a real difference for the people who use them.
The tools and disciplines I rely on to design, build, and ship reliable software.
Designing robust APIs and services with C#, ASP.NET Core, and clean architecture.
Building responsive, accessible interfaces with modern JavaScript, HTML, and CSS.
Modeling and tuning relational schemas with SQL Server and Entity Framework.
Wiring up third-party services, payment gateways, and webhooks with confidence.
Containerizing and deploying apps with Docker and automated CI/CD pipelines.
Writing unit and integration tests that keep releases predictable and safe.
A selection of things I've built recently, from full platforms to focused modules.
An AI-tutored math platform for Grade 6 students: exercise banks, timed tests, parent dashboards, and SePay payments.
A Kubernetes-native Capture-The-Flag platform for FPT University, extended with multi-contest isolation and KYPO Cyber Range integration.
