Work

A production-shaped FHIR R4 ingestion platform demonstrating secure asynchronous backend engineering with synthetic data.

A public, inspectable reference implementation for validation, authorization, event processing, idempotency, and observability.

A live Belize property-discovery and operations platform built around trustworthy inventory, buyer qualification, and real market constraints.

Live with real listing inventory and an agent partnership, with provenance and verification limits built into the buyer experience.

A working review flow with authenticated APIs, persisted analysis, provider fallback behavior, automated tests, and CI.

A reproducible simulation platform for evaluating demand-responsive transit dispatch and learning policies under varied operating conditions.

900 simulation runs across 45 scenario variants, with learning policies improving wait-time and service-rate direction over the greedy baseline.

Security fix accepted and merged upstream as OpenHands PR #1480.

Normalized and analyzed 10,078 failure records to support evidence-based comparison of rail maintenance strategies.

Digitized field and administrative workflows, reducing reported accounting errors by approximately 40%.

Reduced backend latency by approximately 30% while improving recovery paths for field-deployed production systems.
