I’m a senior Java backend engineer with 13+ years of experience building and modernizing enterprise systems, especially with Spring-based architectures. I’ve worked across reactive services, microservices, and event-driven integrations—often using Kafka and Kubernetes—to support high-volume processing, operational dashboards, and reliable back-end APIs. I enjoy turning complex legacy environments into maintainable solutions, collaborating closely with cross-functional teams, and documenting architecture with clear technical artifacts like sequence diagrams. My background also spans financial and healthcare domains, and I’m driven by delivering production-ready software with strong engineering standards, performance focus, and practical cloud-native execution.…I’m a senior Java backend engineer with 13+ years of experience building and modernizing enterprise systems, especially with Spring-based architectures.
