About Me

Get to Know Me

In my recent role at Kotak Bank, I architected an RBI-compliant risk management system using FastAPI, Alembic, and PostgreSQL, significantly reducing manual data processing time by 96% and ensuring compliance. Additionally, I automated financial workflows with Apache Airflow and AWS S3 sensors, achieving 99.8% data validation accuracy. I also developed a Python module for AWS Glue/S3 integrations and database interactions, increasing code reuse by 70%. Furthermore, I implemented Kubernetes-based CI/CD pipelines with automated canary deployments, reducing production incidents by 60%.

When I'm not coding, you can find me exploring new technologies, contributing to open-source projects, or sharing my knowledge through technical writing and community engagement.
