About

Full Stack Developer with 5+ years of experience, skilled in NodeJS, ReactJS, MongoDB, and Postgres. I specialize in backend development with NestJS and have extensive experience integrating Large Language Models (LLMs) like OpenAI, Gemini, Claude, and DeepSeek & AWS Bedrock. My core expertise includes building RAG (Retrieval-Augmented Generation) solutions with LangChain and managing vector databases like Milvus and OpenSearch for advanced semantic search. Additionally, I've developed intelligent AI voice agents leveraging Twilio and Deepgram (STT/TTS) and built AI chatbots and multi-tenant knowledge base platforms for enterprise clients. I also have a strong background in leading projects and teams, and thrive in collaborative, challenge-driven environments. Looking to grow further in a dynamic company where I can continue to leverage and expand my skills.
