Software Developer Jun 2025 – Sep 2026

Centene

• Developed Java 17 and Spring Boot microservices and REST APIs for healthcare capitation configuration and file processing.

• Built reusable React components for healthcare administrative screens, integrating REST APIs to display data and support user workflows.

• Validated required fields, formats, and duplicate records; generated downloadable error reports identifying invalid rows for user correction.

• Implemented SSE processing notifications with heartbeats, stale-connection cleanup, and multiple user sessions, reducing repeated status requests by 70%.

• Optimized PostgreSQL queries and indexes, reducing query execution time by 30%, secured APIs using Spring Security, OAuth2, JWT, and role-based access.

• Deployed containerized microservices on AWS EKS, integrated with Lambda for serverless event triggers, API Gateway for secure endpoint management, and NLB for high-availability load balancing.

• Enhanced developer velocity and code quality by leveraging GenAI tools (GitHub Copilot, Gemini, Cursor, Claude) to draft unit tests and optimize Java patterns, reviewing and testing generated code.

• Supported production healthcare services by analyzing CloudWatch metrics and application logs, investigating processing failures, and coordinating fixes with QA and deployment teams.

• Automated build, test, and deployment workflows using Jenkins; wrote JUnit and Mockito tests and resolved dependency vulnerabilities through library upgrades.

• Contributed to full SDLC via Agile ceremonies: sprint planning, design reviews, code reviews, and retrospectives, maintaining engineering standards and iterative delivery cadence.
