Yangon, Myanmar · Open to new roles

Kaung Htet San

Full Stack Developer, Laravel & React

I build production web systems at Brycen Myanmar. I helped build a contract management platform from scratch in Laravel and React, developed Rakuten, Amazon and Yahoo! store integrations running on AWS, and now work on a Java/Angular retail system for a Japanese client. I use Claude Code every day and pick up new tools quickly.

About

Most of my work has been on systems already in production: reading unfamiliar code, finding where a bug really starts, and fixing it without breaking what works. On my current project that means tracing defects reported by the client's QA team through Angular, Java and SQL, then shipping the fix through GitLab merge requests and a staged CI/CD pipeline.

I'm just as comfortable starting from an empty repository: the contract management platform I helped build began as a blank Laravel + React project. And when a task keeps repeating, I write a small tool for it, like a Python CLI for MySQL dumps or a Chrome script that captures test evidence.

    • Resolve system-test defects reported by the client's Japanese QA team through Redmine and Backlog: reproduce, trace the root cause across Angular, Java and SQL, and ship fixes via GitLab merge requests and a multi-stage CI/CD pipeline.
    • Use Claude Code for AI-assisted development and built internal tooling, including a Python CLI for MySQL dump/restore and Chrome automation for capturing test evidence.
