Hi, I’m Mihnea 👋

I’m a high school student from Romania who likes going deep into how things work — from low-level systems and algorithms to modern AI systems and developer tools.

I started in competitive programming and national olympiads, then moved into AI, cybersecurity, and real-world projects — from AI competitions to contributing to the national AI olympiad ecosystem and building production-style GenAI systems during an internship.

Right now, I’m especially interested in LLM systems, applied machine learning, and tooling that helps developers work more efficiently.
