At Foxsense, I designed and implemented backend architecture for MarketTime’s E-Commerce using Java 17, Spring Boot, and JPA. My work included 15 production REST APIs across six business modules, reducing reconciliation effort by 50%.
I secured backend services with a five-role RBAC model that eliminated 40+ unauthorized API access paths. I also increased SKU import throughput by 20× through JDBC batch operations and reduced partner onboarding from five days to two by publishing OpenAPI specifications.
At Prodapt, I developed Java REST services for enterprise B2B order management workflows and optimized a data pipeline processing over one million records daily, reducing its execution time by 65%. I also improved platform reliability through production debugging and root cause analysis.
