What I'm looking for

I seek roles building production-grade LLM and RAG systems, conversational or voice agents, with emphasis on end-to-end deployment, scalable architectures, and collaborative, growth-oriented teams.

I am a full-stack AI engineer with hands-on experience building LLM-integrated systems, RAG pipelines, and voice agents. I design modular, scalable AI solutions and deploy them with containerization and cloud services for reliable production demos.

At StackNexus, I delivered a SharePoint-integrated proposal chatbot with 85%+ retrieval accuracy and an AI loan-qualification voice agent using ElevenLabs, LangChain, and Twilio. I emphasize reproducible architectures, local LLM integration, and secure API auth.

My background in ECE combined with projects in interview assistants, productivity agents, and math-reasoning agents demonstrates strong end-to-end capabilities: frontend UIs, backend APIs, vector stores, model optimization, and workflow automation.
