What I'm looking for

I’m looking to contribute as a Senior Software Engineer, using Java, Spring Boot, microservices, Kafka, AWS, REST/gRPC, and distributed systems to design scalable, resilient enterprise applications and improve software quality and reliability.

At TSYS, I architect and develop Spring Boot microservices for enterprise payment processing, using Java design patterns to create modular, scalable services.

I connect services to Oracle through MyBatis and support asynchronous transaction workflows with Apache Kafka. I also integrate internal services with third-party applications through REST and gRPC, and use AWS services including Lambda, S3, EC2, and DynamoDB.

Previously, at Globallogic, I developed Spring Boot REST microservices and implemented Debezium with the Outbox Pattern for reliable data propagation. At Hostbooks, I developed REST APIs for financial and GST application modules and delivered reporting capabilities; I’ve also received Spot Awards for UAT onboarding, defect resolution, and fault-tolerant processing.
