I've built AI-powered products end to end, including LLM chatbots, RAG systems, computer-vision pipelines, and backend services.

At Cogilent Solutions, I built machine learning and deep learning pipelines covering preprocessing, experimentation, inference, and evaluation. I also developed data-mining workflows and REST API integrations for internal AI-powered insights.

At Cell Laboratories, I deployed LangChain-based LLM chatbots and built RAG pipelines for context-aware document querying. I also created multi-step agentic workflows with CrewAI to automate business processes.

My projects include 3D CT/MRI segmentation for tumors and organs at risk, a resume-screening RAG assistant, an AI trading bot, and a critic-guided PPO agent that achieved 82.7% held-out success on WebArena-style tasks.
