What I'm looking for

I seek a cloud-native engineering role where I can lead backend architecture, mentor engineers, work in Agile teams, and deliver scalable, secure microservices.

I am an experienced Java microservices developer and team leader with more than five years of backend development experience, skilled in Spring Boot and building scalable RESTful APIs.

I have a strong track record integrating systems (Kafka, Solace, SOAP), securing services with Okta/Spring Security, and deploying with Docker in CI/CD pipelines while using monitoring tools like Kibana and Dynatrace.

At IBM I led high-performing teams, mentored new developers, coordinated with DevOps, QA, architects and product owners, and consistently delivered sprint objectives on time.

I hold a BSc in Computer Science and AWS Developer and Cloud Practitioner certifications, and I seek roles where I can drive backend architecture, mentor engineers, and deliver reliable cloud-native systems.
