About Me

Senior Software Engineer with deep expertise in scalable backend systems, AI/ML, and cloud infrastructure. I architect secure, high-performance solutions that bridge cutting-edge AI with enterprise reliability.

My work spans from designing microservices in Python and Node.js to deploying LLM-based RAG pipelines, and conducting penetration testing to harden infrastructure.

Secure by design, scalable by architecture, intelligent by integration.
