What I'm looking for

I'm looking to lead end-to-end backend delivery for secure, scalable enterprise applications, contribute to architecture and integrations, and mentor engineers within collaborative Agile teams.

I've delivered Java and Spring Boot applications at IQVIA for 100+ enterprise healthcare clients, using HL7 and FHIR interfaces to support secure, scalable integrations.

At Pepcus Software Services, I architected backend capabilities for the PrismHR Connector, built Spring Boot microservices and REST APIs, and supported AWS deployments. I raised automated test coverage from 45% to 85% by establishing JUnit, Mockito, integration-testing, and SonarQube standards for a six-developer team.

I've also built telecom APIs at Ericsson, airfare decision-support APIs at FlyNava Technologies, and HR workflow APIs at Altisource. My work includes PostgreSQL, MongoDB, Kafka, Spring Security, OAuth 2.0/JWT, third-party integrations, and production troubleshooting through Kibana.

I take features from requirements and sprint planning through implementation, testing, and deployment, while mentoring engineers on clean code, secure coding, and design patterns.
