Project Stash Vault

Vault 01 / archive discipline

Aerospace

Mission interfaces, telemetry trust, and operational software for systems that do not tolerate ambiguity.

The aerospace entries are organized around operator clarity, timing pressure, and evidence trails. The through-line is not aerospace aesthetics; it is engineering for environments where system state, human judgment, and traceability have to stay aligned.

Start with the featured case file for the clearest walkthrough in this vault. Lighter entries still keep the same project and repo path.

Archive posture

The flow stays deliberate: browse the archive, open the internal case file, then inspect the public repo when source is wired. Lighter entries keep the same path without pretending to be more complete than they are.

Curated case files

Engineering work documented for deeper review

Read the internal case file first for architecture, decisions, and proof surfaces, then jump to the public repo when source is available.

Flagship file
Live Prototype

An on-chain marketplace for satellite imaging tasks where requesters fund capture jobs, operators bond execution commitments, and escrow settles against verifiable SLA outcomes.

Built

Full-stack system design and implementation across smart contracts, verifier-service architecture, wallet-connected frontend flows, local developer tooling, and deployment-oriented project structure.

Satellite capture agreements are not just procurement records; they are timing-sensitive operational commitments with real failure modes. If requirements, evidence, and payment logic are loosely managed, it becomes hard to prove whether an operator actually met the task or whether a requester is justified in disputing delivery. This project is interesting because it turns an aerospace coordination problem into a system with explicit trust boundaries across contracts, storage, verification, and operator-facing workflows.

Research Track

A provenance rail for mission telemetry that signs critical state changes and preserves an auditable path from raw data to reviewable findings.

Built

Provenance model design, ingestion pipeline architecture, and workflow definition for anomaly review and downstream verification.

In mission environments, raw data alone is not enough. Teams need to know what record was observed, who processed it, what changed later, and whether a conclusion can be defended under review.

Vault 01 / 2025

Launch Window Planner

Live Prototype

A readiness and scheduling console for launch campaigns with typed constraint tracking, timeline visibility, and operator handoff context.

Built

State-model design, timeline interaction design, and architecture direction for a multi-team operational planning surface.

Launch work is often constrained by fragmented operational state. A good planning tool reduces ambiguity at the exact moment teams need to reason across dependencies, not inside isolated discipline dashboards.
