01 / Flagship case studies

End-to-end ownership

Ordered by selected prominence

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 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 bilingual booking and guest-concierge platform for Belize stays, with a public discovery surface and private post-booking portal.

One configurable codebase now serves two property brands with bilingual, structured guest guidance.

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.
