What I'm looking for

I'm looking to build data and AI solutions that improve banking operations, data accessibility, fraud detection, and customer outcomes.

At Axis Bank, I build PySpark and SQL solutions for KYC and New-to-Bank customer mapping, raising mapping accuracy from 75% to approximately 99% and cutting onboarding time from four days to two. I also created self-service data automation tools for 150+ business users and an LLM-based text-to-SQL system with 92% translation accuracy.

I've also developed ML and NLP solutions, including banking fraud detection for 1M+ daily transactions and voice analytics processing 1,000+ hours weekly. My work spans Python, SQL, ETL, AWS, machine learning, and LLM-enabled data products.
