I build secure, high-throughput Java microservices and full-stack transaction platforms on AWS.
United StatesWhat I'm looking for
I've built secure transaction platforms for Visa, Toyota Motor North America, PayPal, and Uber, delivering Spring Boot microservices, REST APIs, and customer-facing web applications. At Visa, I refactored service logic and Oracle SQL/PL/SQL queries to reduce average API response time by 30%, lowering checkout latency for downstream merchants.
I work across Java, Spring Boot, Angular, React, relational and NoSQL databases, and AWS. I've implemented OAuth2 and JWT security, containerized services with Docker and Kubernetes, and automated delivery through Jenkins, Maven, Gradle, and automated testing.
I'm comfortable partnering across UX, frontend, backend, and DevOps teams in Agile Scrum environments, with a focus on reliable production features, efficient performance, and maintainable code.
