· Ensure all data access aligns with governed API and target architecture standards.

· Integrate services with internal systems (policy administration, claims, payments, treasury, identity services) and external portals.

· Collaborate with BPM teams using Appian for workflow orchestration and low/no‑code UI development.

· Work within legacy technologies, including:

§ JSP, HTML, JavaScript, CSS

§ Java on Tomcat

§ Sybase with extensive T‑SQL

§ UNIX batch processing (~800 ksh scripts)

§ SQR reporting

· Participate in modernization efforts while ensuring operational stability.

· Develop and deploy services using AWS technologies (Fargate, Lambda, S3, Aurora PostgreSQL).

· Containerize applications using Docker.

· Support CI/CD pipelines via GitLab.

· Work in hybrid runtime models (on‑prem Docker + AWS).

· Follow disciplined change management and integration governance.

· Write unit and integration tests using JUnit and Mockito.

· Support secure API design using OAuth‑based authentication.

· Engage in code reviews, architectural discussions, and cross‑team collaboration.
