Built Java 8/11, Spring Boot microservices for credit-card and loan processing using REST APIs, Spring MVC, Spring Data JPA, Spring Cloud in a microservices architecture. Designed high-performance APIs for accounts, transactions, and payments, leveraging Java Collections (List, Map, Set, Stream API) and multithreading (ExecutorService, thread pools) to improve throughput and reduce processing time. Deployed and monitored services on AWS (EC2, S3, RDS, CloudWatch), configuring logging, metrics, and alerts to improve reliability and observability of banking services. Developed Angular (v10+) dashboards using TypeScript, RxJS, Angular services, and HTTP interceptors, consuming secured JWT/OAuth2-protected REST endpoints. Implemented Reactive Forms and validation for credit-card/loan application forms, and built responsive dashboards and transaction history pages using HTML5, CSS3, Angular Material/Bootstrap. Wrote JUnit 5, Mockito unit tests and Spring Boot integration/API tests (MockMvc,

Engineered high-throughput microservices and REST APIs; tuned Kafka partitioning and consumer back-pressure, improving p95 latency from 1.2s to 750ms and boosting throughput by 35%. Deployed services on Amazon EKS with HPA for horizontal scaling; automated rollouts with Jenkins and Helm; increased release frequency by 40% and reduced MTTR by 35% using CloudWatch dashboards. Implemented Redis caching and idempotency to reduce duplicate transactions during spikes by ~40%. Hardened endpoints with OAuth2/JWT and RBAC; minimized outage minutes by ~20%. Maintained OpenAPI contracts and test suites (JUnit5/Mockito/REST Assured).

Engineered high-throughput microservices and REST APIs; tuned Kafka partitioning & consumer back-pressure, improving p95 latency from 1.2s to 750ms and boosting throughput by 35%. Deployed services on Amazon EKS with HPA for horizontal scaling; automated rollouts with Jenkins + Helm; release frequency +40% and MTTR –35% via CloudWatch dashboards. Implemented Redis caching + idempotency to remove ~40% duplicate transactions during spikes. Hardened endpoints with OAuth2/JWT and RBAC; reduced outage minutes –20%; maintained OpenAPI contracts and test suites (JUnit5/Mockito/REST Assured).
