What I'm looking for

I'm looking to build scalable backend APIs, ETL pipelines, and cloud data platforms where I can solve complex fintech, healthcare, or enterprise automation problems with Python, AWS, and modern CI/CD practices.

I've built backend, data integration, and fraud-prevention systems for Mastercard, Bank of America, ICICI Bank, and healthcare applications. My work spans high-volume payment data, financial analytics, digital loan processing, and intelligent automation.

At Mastercard, I developed and tested fraud-detection backend components, validated Django REST Framework services, and optimized AWS S3 object listing with aioboto3 and parallel pagination across multiple buckets. I also supported Lambda-based validation workflows, database integrity checks, and GitHub Actions CI/CD pipelines.

For Bank of America, I built Python ETL pipelines with Azure Data Factory, Azure Data Lake, Databricks, PySpark, Pandas, and NumPy, while developing FastAPI services for downstream analytics. I’ve also delivered Django applications and secure REST APIs for loan onboarding, KYC, credit scoring, JWT authentication, RBAC, and AWS S3 document storage.

I bring 5.3+ years of experience using Python, Django, DRF, FastAPI, PostgreSQL, AWS, Docker, automated testing, and practical system design to build reliable production software.
