Technical Leadership
- Lead end-to-end design, development, and delivery of enterprise Java/J2EE applications.
- Provide technical direction, mentorship, and guidance to a team of 5–10 software engineers.
- Conduct code reviews, enforce coding standards, and champion engineering best practices including TDD and BDD.
- Drive architectural decisions across microservices, API design, and UI layers.
Backend Development
- Design and develop scalable Java (11/17) and Spring Boot / Spring Framework microservices.
- Build RESTful APIs and integrate with enterprise messaging platforms — Apache Kafka and IBM MQ.
- Deploy and manage applications on WebSphere Application Server (WAS) and container platforms (ECS / OpenShift / Kubernetes).
