Developed and maintained Spring Boot microservices for business-critical workflows, following clean architecture and SOLID principles. Designed and exposed RESTful APIs with consistent request/response contracts and backward-compatible changes. Implemented configuration management using profiles and externalized properties for multiple environments (dev/test/prod). Built Spring Batch jobs to process high-volume data using chunk-oriented processing (ItemReader/Processor/Writer). Implemented batch features including job/step restartability, re-runs, skip/retry policies, and execution tracking. Implemented persistence layer using Spring Data JPA (repositories, custom queries, pagination/sorting). Designed and optimized entity mappings (relationships, fetch strategies) to improve query performance and reduce N+1 issues. Added database constraints and indexing considerations aligned to application access patterns. Implemented clear validation error responses to improve API usability and reduce downstream failures. Handled common failures including validation errors, resource not found, data integrity violations, and unexpected server errors. Implemented multithreading/async processing using thread pools and asynchronous execution to improve throughput while maintaining thread safety and transaction boundaries.
