Designed and built secure, high-throughput digital banking features (payments, account services, credit card servicing, and customer onboarding) using Java 17, Spring Boot, Spring Cloud, and React/TypeScript. Built 15+ RESTful microservices with Resilience4j, improving average API response time by 38% through caching, pagination, and query tuning. Engineered Kafka-based event-driven payment and card transaction processing handling 2M+ events/day using at-least-once delivery, idempotent consumers, and dead-letter queues, reducing reconciliation effort by 40%. Containerized services with Docker and deployed to Kubernetes (Azure AKS) using Helm and Azure DevOps pipelines, reducing release time from 3 hours to 25 minutes. Hardened authentication/authorization with OAuth2, OpenID Connect, and JWT and remediated critical/high security findings to meet bank security and compliance standards. Improved observability with Splunk/Grafana/Dynatrace and reduced MT T D by 40% while sustaining 99.95%

Developed and enhanced policy administration, quoting, billing, and claims services for property and casualty insurance using Java 11/17, Spring Boot, and Hibernate. Delivered a microservices-based quote-and-bind platform (rating, eligibility, payments) that reduced average quote turnaround from 8s to 3s, supported 20% growth in online policy sales, and increased quote-to-bind conversion by 12%. Integrated third-party rating, payment, and credit-bureau APIs via REST/Feign with resilient retry/timeout patterns, achieving a 99.9% integration success rate. Implemented asynchronous claim intake workflows with Kafka and Spring Batch, cutting manual processing effort by 35% and accelerating claim registration by 50%. Built Angular and TypeScript single-page applications for broker and agent portals with role-based access control, improving task completion time by 27%. Tuned Oracle/SQL Server queries and JPA to remove N+1 issues and reduced nightly batch windows from 4h to 2h10m. Automated CI

Built full-stack clinical and patient-facing applications supporting province-wide healthcare operations using Java 8/11, Spring Boot, Angular, and Oracle. Developed secure REST APIs for appointment scheduling, patient records, and lab result handling with privacy-compliant audit logging and encryption, serving 500K+ requests/day. Created responsive Angular UI modules using reactive forms and RxJS, reducing data-entry errors by 32% and improving clinician workflow efficiency. Modernized a legacy Struts/JSP application into Spring Boot and Angular components, cutting page response time by 45% and reducing maintenance effort by 30%. Implemented HL7 and FHIR integrations to exchange patient data between hospital systems with 99.9% message accuracy. Integrated Spring Security with SAML and Active Directory SSO for 20K+ healthcare staff. Containerized applications with Docker and automated CI/CD with Jenkins and Maven to reduce manual deployment steps by 70%. Optimized Oracle SQL/PLSQL pack
