👋 Hi, I'm winuim

I'm a freelance software engineer based in Japan, focusing on backend development with C#/.NET and AWS.

I build practical tools to solve real-world development problems. One of my main projects is SemanticStub, a semantic-aware API mock server designed to improve API development workflows, especially in AI-assisted environments.

🚀 What I’m working on

  • SemanticStub – smarter API mocking with semantic matching
  • AI-assisted development workflows (Codex, agents, etc.)
  • Scalable backend systems on AWS

❤️ Why sponsorship matters

Maintaining and improving open-source projects takes time and effort.
Your support helps me:

  • Continue developing and maintaining tools like SemanticStub
  • Experiment with new ideas in AI-driven development
  • Share practical knowledge with the developer community

If you find my work useful, I’d really appreciate your support 🙌
