Message

At IBM, I engineered and deployed three full-stack AI applications using React, Python, FastAPI, and PostgreSQL. I also built RAG pipelines that improved answer accuracy from 72% to 89% on a 300-query benchmark.

Previously, I built cloud applications and REST APIs at Aspire Tech, and worked on banking features at HCLTech, including a card replacement feature for 2.5 million users. In personal projects, I contributed to a fraud detection system and built an enterprise knowledge assistant with source-cited answers.
