Technical Skills
Work Experience
- Designed and maintained Spring Boot microservices for insurance policy and claims workflows, improving platform reliability to 99.5% uptime through resilient service design and Spring Cloud integrations.
- Implemented secure REST and SOAP APIs with Spring Security and OAuth2/JWT-based RBAC, enforcing enterprise compliance and API versioning for policy lifecycle management.
- Optimized backend performance by introducing database indexing and a distributed caching layer, reducing average API latency from 800ms to 180ms and lowering DB load by ~60%.
- Engineered event-driven claim notification pipelines using Apache Kafka to decouple processors and handle over 10k claim events/hour, increasing throughput and fault tolerance during peak windows.
- Established CI/CD pipelines with Jenkins, containerized services with Docker and Kubernetes (EKS), enabling on-demand zero-downtime deployments across environments.
- Improved observability using CloudWatch, Prometheus, and Grafana with centralized logging and metrics, shortening mean time to repair (MTTR) for production incidents.
- Built Spring Boot microservices and Kafka-based event flows for an order management system that processed 50K+ daily transactions, improving consistency across fulfillment, payment, and notification services.
- Architected flexible product catalog storage using MongoDB to support dynamic product schemas, enabling faster feature rollout and flexible querying for product data.
- Implemented Redis-backed caching patterns and API optimizations to achieve sub-100ms response times for real-time inventory reads during peak traffic.
- Delivered responsive Angular admin portals integrating REST and GraphQL endpoints to enable dynamic querying and accelerate product management workflows.
- Automated CI/CD with Jenkins and GitHub Actions and deployed services to Azure with autoscaling policies, increasing release frequency and improving environment parity.
- Containerized services with Docker and orchestrated with Kubernetes; implemented Grafana dashboards to monitor latency, throughput, and error rates for client stakeholders.
- Contributed to decomposing a legacy monolith into Spring Boot microservices, increasing modularity and enabling independent service scaling and deployments.
- Designed and implemented RESTful APIs with Spring Boot and Spring Data JPA, documenting endpoints with Swagger/OpenAPI to improve developer onboarding and integration.
- Reduced average query execution time by 30% across three modules by applying JPA query tuning, indexing strategies, and Spring transaction management.
- Wrote unit and integration tests with JUnit and Mockito achieving ~80% coverage for assigned modules and driving a measurable reduction in post-release defects over consecutive sprints.
- Participated across SDLC activities in Agile Scrum teams, from requirements analysis through deployment and production support, improving sprint delivery predictability.
- Supported post-release debugging and root-cause analysis using structured logging (SLF4J), lowering time-to-triage for production issues.
