What I'm looking for

I'm looking for opportunities to build secure, scalable cloud-native backend platforms and AI/ML-powered products in collaborative Agile teams. I'm open to relocation and require visa sponsorship.

At Microsoft, I architect backend services for clinical analytics platforms, optimizing full-text search across enterprise radiology datasets. I improved PostgreSQL query performance and indexing strategies to reduce average response latency by 25%.

I've led authentication migration from Mozilla OIDC to Microsoft Entra and remediated vulnerabilities through S360, raising the platform security score above 90% while meeting SDL and OWASP compliance.

Previously at ZS Associates, I built Python and Scikit-Learn models using XGBoost and Random Forest, improving product launch decision accuracy by 10% and model accuracy by 12%. I also built AWS data archival and ingestion pipelines with S3, Lambda, and Glue.

I've delivered Django, Flask, and REST API products including a property management platform for 10,000+ active users and a secure document-upload module for the Pune Smart City Initiative.
