At American Express, I own the development and production reliability of Python and Java backend services supporting payment workflows. I modernized legacy components into Spring Boot and Python microservices and designed Kafka-based event processing integrated with AWS, increasing throughput by approximately 30%.
I’ve improved delivery and reliability by building reusable CI/CD pipelines, automating Kubernetes deployments, and expanding automated tests with Pytest and JUnit. I also optimized PostgreSQL queries and Redis caching, and strengthened service observability with Prometheus and Grafana.
Previously, at EPAM Systems, Endava, and Cognizant, I developed backend services, REST APIs, and database integrations for enterprise applications. I also contributed to React application integrations, deployment automation, and testing across those roles.
