Backend Architect & Security Researcher
About
Software engineer with a hacker mindset. I break things to understand how they work, then build them better. I stay close to the terminal, keep studying, keep hacking, and treat each project as a chance to explore ideas creatively. Fluent in Python, JavaScript, C++ and whatever the challenge demands, with a strong pull toward security research, penetration testing, and understanding systems deeply before the bad actors do.
Focus: Security Research • AI/LLM • Web3 • IoT Hacking • DevSecOps
