Lead AI Engineer
Spearheaded the integration of GitHub Copilot and Claude Code into the daily development cycle. Automated the generation of Golang/.NET microservices scaffolding and boilerplate, fundamentally shifting how the team initialized new backend architectures and reducing development cycle time by over 30%.
Backend Innovator
Designed prompts and leveraged AI agents to automatically generate exhaustive unit test scenarios and edge cases for critical gRPC contracts in the International Money Transfer (IMT) system. This automated verification suite allowed the framework to easily achieve and maintain over 90% code coverage reliably.
Architect Consultant
Outside of core development, I actively participate in open-source projects and freelance architectural consulting. I primarily help tech startups design secure, highly available, cloud-native backend systems using cutting-edge AWS and GCP managed services.
Senior Backend Engineer
Designed and built a high-throughput payment processing gateway handling 10,000+ TPS with sub-200ms latency. Implemented event-driven architecture with Kafka for real-time transaction streaming, Redis for idempotency caching, and Circuit Breaker patterns for downstream service resilience.
DevOps Lead
Led the migration of 15+ legacy monolithic services to GKE-based microservices architecture. Designed Terraform IaC modules for reproducible multi-environment provisioning. Built CI/CD pipelines with GitHub Actions achieving 99.5% deployment success rate and < 5 min rollback capability.
Full-Stack Developer
Built a real-time analytics dashboard processing 2M+ daily events from multiple e-commerce platforms. Leveraged BigQuery for data warehousing, Pub/Sub for event ingestion, and React for a responsive frontend with interactive charts, filters, and exportable reports.
Backend Architect
Architected a HIPAA-compliant document management platform for a financial services client. Implemented end-to-end encryption, role-based access control (RBAC), and audit logging with DynamoDB. Passed Fortify security scans with zero critical vulnerabilities.
Backend Engineer
Developed a multi-tenant notification engine supporting email, SMS, push, and in-app channels. Built with RabbitMQ for message queuing, rate-limiting per tenant, template rendering with Handlebars, and delivery tracking with retry logic and dead-letter queue management.
