Platform Engineer specializing in distributed systems, event-driven architecture, and production infrastructure.

Currently building SecureDrop — an authentication platform demonstrating production-oriented microservices architecture.

Distributed Authentication Platform with production-focused distributed systems design.

• 11-microservice ecosystem with clear domain boundaries
• Apache Kafka event streaming with Dead Letter Queue (DLQ) and retry mechanisms
• Polyglot persistence (MySQL + MongoDB + Redis)
• Kubernetes deployment architecture with ArgoCD GitOps workflows
• 73+ automated tests (85%+ coverage)
• Zero-trust security model with JWT rotation and RBAC
• Full observability stack (Prometheus + Grafana + structured logging)
• Multi-stage CI/CD pipeline using GitHub Actions
