What I'm looking for

I'm looking to build AI, knowledge graph, and distributed systems that automate complex workflows, solve meaningful optimization problems, and deliver measurable product impact.

At PhysicianX, I architected an autonomous web crawler running 3 million daily activities and built a full-stack RAG-AI assistant that reduced internal document retrieval time by 20%.

Previously at Credit Suisse, I led graph-data and platform modernization across an 18-service microservices architecture, including zero-downtime Neo4j and Java migrations. I built event-driven Spring Boot services, optimized ETL and database queries by 80%, and helped maintain 99.9% workflow uptime.

I'm also a graduate researcher at the University at Buffalo, applying graph learning and reinforcement learning to robot co-design, satellite debris capture, and GPS-denied drone flight. My work includes knowledge graphs, GraphRAG, NLP ingestion, and scalable graph databases.
