I'm a resourceful and security-aware Machine Learning & MLOps Engineer with strong full-stack foundations and a hacker mindset. I'm passionate about building scalable AI systems, automating workflows with LLM agents, and deploying production-ready NLP pipelines using modern MLOps tooling. I enjoy navigating complex Linux environments, architecting containerized services, and leveraging DevSecOps principles. As a self-driven learner, I have a deep interest in cybersecurity, offensive tooling, and privacy-respecting technologies. In my free time, I love solving CTF challenges on platforms like HackTheBox and TryHackMe. I am equally comfortable writing Python for LLM orchestration, managing infrastructure with Docker & CI/CD, or diving into React / Next.js for product-facing applications.…I'm a resourceful and security-aware Machine Learning & MLOps Engineer with strong full-stack foundations and a hacker mindset.
