Full Stack Engineer / Security Research

I build software and spend a lot of time understanding how it actually works.

I work across backend and frontend systems, focusing on debugging complex behavior and improving architecture. I enjoy reading code deeply and tracing how systems fail.

Alongside development, I analyze real-world OSS code and conduct security research on web applications and crypto implementations.

I’m currently building:

• Self-balanced memory (life logging & analytics app)
• CryptoLab (cryptography learning platform)

I also work on infrastructure with AWS and CI/CD pipelines using GitHub Actions.

I like understanding systems from both sides: how they are built, and how they break.
