Phelipe Honesto (PhelipeHonesto) builds AI agent systems and data infrastructure for private aviation: flight-data ingestion, entity resolution over operators and aircraft, charter-brokerage orchestration, and memory for the agents that run it. The core stack is Dumont Agent, OSA Data Platform, and ph-brain.
Tip
Former airline first officer turned software builder. 2,000+ flight hours, 1,000+ airline flights, now shipping spec-first, test-heavy systems for the industry I flew in. Built under Orange Sunshine Aviation · Writing at Loud Hawk

OSA Data Platform ingests and resolves. ph-brain remembers. Dumont reasons and acts. Loud Hawk publishes what the data says.

| Layer | System | Responsibility |
|---|---|---|
| Ingestion | OSA Data Platform | Pull ADS-B, FAA registry, and NTSB data into one schema-validated store |
| Entity resolution | OSA Data Platform | Collapse messy records into canonical operators, aircraft, and tail numbers |
| Memory | ph-brain | Structured ingestion of documents, notes, and media into an embedded knowledge substrate, served over MCP |
| Agent control | Dumont Agent | Run the charter pipeline with validation gates at every stage and learn from closed deals |
| Publishing | Aviation News Aggregator → Loud Hawk | Turn industry news and data signals into an aviation intelligence newsletter |
| Project | What it is | Evidence | Stack |
|---|---|---|---|
| dumont-agent | AI charter-brokerage orchestrator: intake → validation → quoting → operator sourcing → close, with a learning loop over closed deals | 681 tests · 22/25 end-to-end scenarios · auth enforced on every private route · MCP server (17 tools) · CI | TypeScript, Vitest, Zod, Postgres, MCP |
| osa-data-platform | Aviation data platform: ADS-B / FAA / NTSB ingestion, canonical entity resolution, analytics compute | 21M flight legs · 484 tests · LLM resolution eval: 0 false matches, 0 fabricated IDs · CI | TypeScript, Supabase / Postgres, pgvector |
| ph-brain-engine | Personal intelligence substrate: embeds a markdown vault and serves hybrid semantic + keyword search to agents over MCP | 22 tests · CI · retrieval core ported from GBrain (MIT) | TypeScript, Bun, Voyage AI, pgvector, MCP |
| Aviation-News-Aggregator | Loud Hawk v2: 74-source aviation catalog (25 active by default), 14 fetch strategies, per-source circuit breakers, authority-weighted ranking | API smoke tests · CI · Docker | Python |
Flight decks run on checklists, so my code does too.
| Practice | What it means in the repo |
|---|---|
| Spec first | Every system ships with a written specification before code (SPARC-style) |
| Test heavy | 1,100+ tests across the stack; validation runs at every pipeline stage, not only at the end |
| Schema at the edges | Zod validation on every ingest and every agent handoff |
| Evaluation over vibes | LLM steps get eval harnesses and scored passes before they're trusted |
| Ship small, ship visibly | CI on every push, containerized deploys, documented dev workflows |
| Goal | Project |
|---|---|
| See a multi-stage AI agent with validation gates | dumont-agent |
| Ingest and resolve FAA / ADS-B / NTSB data | osa-data-platform |
| Build an MCP-served personal knowledge base | ph-brain-engine |
