 About

I'm a Computer Science student building things that interest me — from parking systems that see cars with AI, to SAT solvers that run 150,000× faster than brute-force, to physics engines you can throw boxes around in.

Most of my time goes into full-stack engineering and offensive security. I like understanding how systems work under the hood, whether that means implementing CDCL from scratch or exploiting JWT forgery bugs in a CTF.

  • 🎓  BSc Computer Science (English) — West University of Timișoara (2024 – 2027)
  • 🔐  Google Cybersecurity Seminars — Selected participant, SOC simulations & offensive security
  • ⚡  Outside of code: JDM cars, sim racing, hardware tinkering

 Achievements



Built Parkie in 48h — a computer-vision parking system using YOLOv11 + FastAPI + React Native. Personally owned the backend and admin dashboard.

Community Problem Track Award · Timișoara


Exploited JWT forgery vulnerabilities and e‑commerce business logic flaws. Automated attack pipelines with custom Python scripts across Web, Crypto, and Stego.

Ranked 101 / 350 Teams · Feb 2026

 Featured Projects

AI-powered smart parking with real-time availability. Camera feeds run through YOLOv11 with polygon-based slot matching, occupancy streams to a React Native mobile app via Supabase Realtime, and lot owners manage slots through a canvas-based Vite + TypeScript admin dashboard.


Transforms university tasks into RPG quests with XP, levels, achievements, streaks, and a global leaderboard. Spring Boot REST API with JWT auth, Pessimistic Locking for concurrent XP updates, async task verification, and a React 19 SPA with Catppuccin dark theme.


Four Boolean Satisfiability algorithms in C++17. The CDCL solver uses 1-UIP conflict analysis, non-chronological backtracking, and VSIDS-like heuristics — solving complex 3SAT instances up to 150,000× faster than brute-force.


Custom 2D physics engine with angular dynamics, OBB + SAT narrow-phase collision, grid-based broad-phase spatial partitioning, and momentum-preserving mouse interaction — grab, flick, and throw objects with realistic impulse transfer.
