At CSG International, I own Java and Spring Boot microservices supporting enterprise telecom billing platforms processing 1M–10M transactions daily. I've defined API contracts, production deployments, persistence models, fault handling, and on-call reliability for high-throughput workflows.
I've established API versioning standards across 7+ engineering teams, reducing integration defects by 25%, and built Azure DevOps CI/CD gates that reduced build failures by 30% and achieved 99.8% deployment reliability. I also led security hardening across four production services, addressing 15+ medium-to-high severity vulnerabilities aligned with OWASP controls.
Previously, I built telecom firewall microservices at Telaverge Communications and owned AWS infrastructure, Terraform provisioning, and database performance improvements at CSG. My work spans distributed systems, real-time telecom signaling, and reliable cloud delivery.
