Architected and owned end-to-end delivery of a loan origination platform (Java 17, Spring Boot 3, Angular 14, PostgreSQL) serving 10,000+ concurrent users at 99.9% uptime, spanning backend, frontend, REST APIs, and AWS deployment. Built 15+ Spring Boot microservices exposing RESTful APIs and handling 50K+ daily requests; introduced Redis caching and rate limiting, cutting database load ~30% and p95 latency from 800ms to 200ms. Integrated Razorpay and Stripe payment gateways for loan disbursement and EMI collection, implementing webhook handling, retries, and idempotency keys to ensure zero duplicate transactions. Shipped an LLM-powered PDF review assistant (Spring Boot, LangChain, GPT-4 RAG) that cut manual document review time by ~40%, and automated 15+ hours/week of payment and e-sign workflows using Spring Batch. Protected downstream services with Spring Cloud Gateway rate limiting and Resilience4j circuit breakers; instrumented real-time Prometheus/Grafana dashboards for monitoring and alerting. Hardened 8 REST services with Spring Security JWT-based authentication and RBAC, reducing unauthorized-access incidents by ~60%; eliminated Hibernate N+1 queries and tuned SQL, improving the slowest endpoints by 45%. Replaced polling with a WebSocket-based real-time notification service for loan status and payment confirmations, cutting notification latency from minutes to seconds. Containerized services with Docker on AWS (EC2, ECS, Lambda, S3) behind Jenkins / GitHub Actions CI/CD pipelines; raised test coverage to 85%+ with JUnit 5, Mockito, and Testcontainers quality gates.
