Work
Systems I designed and built for employers over 15+ years — banking, payments, and large-scale retail. The source is proprietary, so there’s nothing to link to; the systems themselves are the portfolio.
JPMorgan Chase · 2023–2026
High-throughput Spring Boot microservices processing thousands of messages per second — manual Kafka offset commits to guarantee zero data loss, backed by automated Dead Letter Topic reconciliation. Maintained 99.99%+ streaming uptime under peak load while eliminating data drift and manual intervention in failure recovery.
JPMorgan Chase · 2023–2026
Led the modernization of document archival and purging workflows for the CCB Risk Aggregation Portal, migrating legacy SharePoint .NET/C# logic into the core Java monolith while maintaining full regulatory compliance history. Streamlined legacy stack complexity, driving a ~25% boost in operational processing efficiency and reducing infrastructure maintenance overhead for audit compliance.
JPMorgan Chase · 2023–2026
Developed Karate automated API test suites and an endpoint-driven event service enabling cross-functional teams to test EKS-hosted microservices without requiring direct cluster access; built and configured automated deployment pipelines in Jules. Unblocked multi-team testing dependencies, accelerating release cycles and reducing test setup overhead for containerized microservices across cloud environments.
The Home Depot · 2020–2023
Scalable microservices built with Java Spring Boot and Node.js across GCP and PCF — integrated GCP Pub/Sub for decoupled event-driven processing, managed multi-database workflows (Firestore, CouchDB, MySQL), and leveraged BigQuery for high-volume analytics. Automated multi-environment infrastructure provisioning with Terraform and Concourse CI/CD pipelines, cutting deployment overhead by 40% while establishing end-to-end API visibility via GCP Cloud Logging and Monitoring.
Verizon · 2016–2019
Partnered closely with system architects and engineering managers to design and deploy low-latency RESTful Spring Boot microservices on AWS EC2, and built event-driven messaging architectures using AWS SQS, SNS, and Lambda with secure OAuth2 authentication across backend layers. Engineered on-premise search services for the core Verizon website and built enterprise event-driven Pub/Sub applications leveraging Spring JMS and Oracle DB; optimized database access patterns to improve API response times by 20%.
First Data (Fiserv) · 2014–2016
Served as Lead Backend Developer for a greenfield platform (rebranding promotional offers into enterprise promotion services), partnering directly with enterprise architects and product managers while guiding junior engineers and consultants to deliver initial development environment releases. Architected SOAP and RESTful web services using Java and Spring WS; optimized SQL Server and MySQL database queries to handle large-scale batch transaction processing and reduce turnaround times.
