About Me

Classified data detected. Hover or tap redacted blocks to decrypt.

I am a resourceful and results-driven professional, offering a unique blend of expertise in full-stack software engineering, proactive cybersecurity, and AI-assisted development. My core foundation lies in designing and building scalable, modern web applications leveraging React, Next.js, Angular, and theNode.js ecosystems. What sets my approach apart is a deep understanding of offensive and defensive security primitives—from hands-on penetration testing and vulnerability assessmentsto implementing robust SOC operations and threat mitigation strategies. Furthermore, I actively integrate advanced AI agents and LLM tooling—such as Gemini, Claude, and ChatGPT—into my engineering workflows to accelerate prototyping, automate complex tasks, and drive innovation. By combining agile development practices with a security-first mindset and cutting-edge artificial intelligence, I am dedicated to delivering highly performant, secure, and forward-thinking technological solutions.
