- Advanced AI Systems: Specialized in Generative AI and Agentic Workflows. I build autonomous systems using LangChain, LangGraph, and Model Context Protocol (MCP) while optimizing RAG pipelines.
- Cloud Infrastructure: Orchestrating containerized deployments using Docker and Kubernetes (AKS) to ensure exceptional system availability.
Tech Stack Highlights:
- Backend: Java, Spring Boot, FastAPI, Kafka
