Supporting mission-critical applications in a high-security government environment, I lead full-stack development and production support initiatives that drive system reliability, scalability, and performance across enterprise platforms. Provide 24/7 production support for highly sensitive government systems, ensuring stability and rapid incident resolution. Design and maintain modular full-stack solutions using Java 21, Spring Boot, Node.js, Angular 19, and Express.js, improving code maintainability and scalability. Develop TypeScript-based microservices with layered architecture, cutting defect rates by 20% and enhancing code reusability across multiple platforms. Optimize Oracle repository layer queries, reducing execution time for high-volume joins and stored procedures. Achieve 90%+ unit/integration test coverage using Jest and Mockito, improving code quality and release confidence. Automate CI/CD pipelines using Jenkins, GitHub Actions, and Docker, streamlining deployments and minimizing release failures. Enhance system observability with centralized logging (Log4j, Splunk) and real-time dashboards (Grafana, Prometheus). Lead incident triaging and root cause analysis, reducing MTTR by 40% across critical services. Implement Angular 19 UI enhancements for dynamic dashboards, real-time error feedback, and responsive design. Integrate AWS services (EC2, Lambda, S3, RDS) to optimize deployment architecture and reduce operational overhead. Refactor monolithic modules into reusable utilities (e.g, JsonConverter, ErrorHandler), reducing code duplication and technical debt. Build custom GitHub Actions workflows in YAML to automate integration, testing, and release pipelines. Collaborate across Agile teams, participating in sprints, bug triage, and cross-functional planning to deliver secure, resilient applications on time.
