Summary

I engineer immutable, observable systems — double-entry ledgers and healthcare APIs where correctness, security, and operational clarity are design invariants, not afterthoughts. Every deployment is Git-backed, Terraform-defined, and verified with the same rigor the systems themselves demand.

Experience

Engineering Lead — Ledger-Core — immutable double-entry ledger, fintech

2026 — Present
  • Built an immutable double-entry ledger with CQRS, optimistic concurrency, and outbox messaging for exactly-once event publishing
  • Designed append-only reconciliation so audits become a proof, not a process
  • Shipped end-to-end OpenTelemetry traces across API, worker, and queue

Engineering Lead — Med-Core — healthcare intake API, healthtech

2026 — Present
  • Built a FastAPI intake pipeline with field-level PHI encryption and OAuth2/JWT scoped auth
  • Deployed to Azure Container Apps with Terraform and scale-to-zero, verified in production
  • Hardened CI with dependency and container scanning after a base-image advisory

Projects

  • Ledger-Core — Immutable double-entry ledger with CQRS, optimistic concurrency, and outbox messaging
  • Med-Core — Healthcare intake API with PHI encryption, OAuth2/JWT auth, and Redis rate limiting
