I build high-scale backend platforms for payments, healthcare, and enterprise operations.

I've built transaction-heavy backend platforms at J.P. Morgan, Anchorstacktech, and DATAMARK, INC., spanning payments, travel, healthcare, order management, and data integration.

At Anchorstacktech, I architected a Python, Django, and PostgreSQL order management microservice processing more than 500,000 daily transactions, cutting latency from 450ms to 190ms. I also migrated legacy invoice systems to distributed Python/Django and AWS Lambda, reducing monthly infrastructure costs by 40%.

At J.P. Morgan, I led a cloud-native e-commerce payment platform handling 1.2 million daily transactions and designed an event-driven notification system managing more than 5 million messages each day. I build secure REST APIs, optimize complex SQL, and modernize monoliths into resilient containerized microservices.

I'm passionate about mentoring engineers, improving delivery through automated testing and CI/CD, and solving complex business problems with reliable cloud-native systems.
