Mingyu H.

I’m a versatile software engineer who loves turning real-world workflows into dependable, well-instrumented software. My work spans system design, full-stack web, and backend development, with a toolbox centered on Java, Python, TypeScript, and C++. I’ve built and maintained applications using FastAPI/React/PostgreSQL, Node/Express/TypeScript, Spring Boot/MVC, and ASP.NET MVC—owning REST APIs, auth/validation, testing, and iterative releases. On the data side, I’m comfortable with PostgreSQL, MySQL, and MongoDB, with a solid grasp of transactions, indexing, and query tuning. I use Docker and GitHub Actions to keep CI/CD smooth and have working knowledge of AWS for deploys and monitoring. Front-end wise, I focus on clean React and modern JS/TS patterns that make flows obvious and fast. I’m pragmatic, detail-oriented, and collaborative—strong at debugging, communicating tradeoffs, and shipping scalable solutions that balance reliability and product polish.
