Backend Systems • Cloud Platforms & DevSecOps • Applied AI
I build software where backend design, cloud operations, and AI integration meet. Current work includes an immutable .NET 10 ledger, a security-focused FastAPI intake service, and queued AI document processing on Azure Container Apps.

Engineering Capabilities
Deployed work spans application and platform engineering. Applied AI currently centers on structured outputs and queued model jobs; RAG with pgvector, deterministic tool use, and provider resilience are the next implementation track.

FINANCIAL TECHNOLOGY
Ledger-Core v1.0 v1.0
ProductionC# and .NET 10 ledger with append-only double-entry records, CQRS through MediatR, RowVersion concurrency control, and a T-SQL outbox with Redis idempotency for RabbitMQ delivery.
HEALTHCARE & DEVSECOPS
Med-Core v1.0 v1.0
LiveFastAPI intake service that encrypts protected fields at the request boundary, applies scoped OAuth2/JWT access and Redis controls, and deploys to Azure Container Apps through Terraform and GitHub Actions.

- JournalFirst scale-to-zero verification on Azure Container Apps
Deployment log for the first verified scale-to-zero run on Azure Container Apps: zero replicas overnight, KEDA-triggered warm-up on the first request, and the cold-start latency budget observed before and after.
- ADRAzure Container Apps with Scale-to-Zero for Cloud-Native Microservices
Adopt Azure Container Apps scale-to-zero as the standard deployment posture for background workers and non-critical APIs: minimum replicas of zero, HTTP-triggered scaling for APIs, and event-driven KEDA triggers for queue workers.
- JournalRedis idempotency keys — tuning the reconciliation retry storm
Post-mortem on a retry storm that pushed 12 duplicate outbox deliveries through Redis: the TTL mismatch, the idempotency-key fix, and the monitoring gap that hid it for three hours.
