Design, develop, and maintain scalable backend microservices using Spring Boot in a cloud-native environment. Implement data persistence with Spring Data JPA and Hibernate; manage Flyway migrations; handle transactions and ensure data consistency across distributed systems. Develop RESTful APIs, implement event-driven architectures using Kafka, and integrate Redis caching to improve performance. Write automated tests with JUnit and Mockito; design and deliver production-grade SPAs with Angular; integrate frontend with backend APIs and implement NgRx for state management. Collaborate with UX/UI teams, deploy containerized apps on Kubernetes/OpenShift, and implement CI/CD pipelines using GitLab CI, ArgoCD, and Tekton. Perform automated REST API testing with Playwright and Postman; monitor, troubleshoot, and optimize system performance.

Full Stack Consultant at CIBC

February 1, 2022 - Present

Designed and developed real-time, event-driven microservices using Spring Boot and Apache Kafka (Connect, Streams, ksqliDB); integrated Kafka with AWS services (EventBridge, S3, DynamoDB, RDS) to build cloud-native workflows for large-scale financial transactions. Managed schema governance with Kafka Schema Registry and ensured security via RBAC/ACLs/SSL-TLS and OAuth 2.0. Optimized throughput with tuned brokers/partition strategies and implemented robust error handling. Built CI/CD pipelines (GitHub Actions, Jenkins, Tekton, ArgoCD), implemented monitoring (CloudWatch, Prometheus, Datadog), and performed cloud cost optimization. Developed SPAs with React/TypeScript; later migrated modules to Angular; created reusable UI components; implemented JWT-based security and role-based routing. Migrated legacy monoliths to microservices on Docker/Kubernetes/OpenShift; implemented Flyway migrations and Redis caching; authored unit/integration tests; mentored juniors and contributed to architect
