I’m an AI & back-end engineer building production-ready, retrieval-augmented and agentic systems that help enterprises automate knowledge access and workflows. I specialize in advanced RAG architectures, scalable cloud backends, and fast, reliable API services—often integrating LLMs with vector and graph-based retrieval for low-latency, high-accuracy results. Across my work and freelancing, I’ve designed end-to-end systems that combine tools like FastAPI, async Python, LangChain/LangGraph, and hybrid search/reranking, and deployed them on AWS and Azure infrastructure. I also develop real-time AI experiences (including voice and WhatsApp integrations), focusing on practical reliability: robust pipelines, strong observability, and secure, multi-tenant data handling.…I’m an AI & back-end engineer building production-ready, retrieval-augmented and agentic systems that help enterprises automate knowledge access and workflows.
