Shipyard Operations Software
Software Engineer / Project Lead (contract)
Make the consequences of a disrupted plan visible.
Designed, built, and deployed shipyard-planning software connecting installation tasks, parts, personnel, and shared equipment in a PostgreSQL ontology, with Rust and Python/FastAPI services and a React/TypeScript operator interface.

- Operational result
- Planners can trace downstream disruptions and evaluate alternatives. O3 and defense partners have begun using the work as a framework for planning upcoming shipyards and distributed shipbuilding.
- Connection to forward deployed engineering
- Customer discovery, full-stack delivery, and operational feedback.
- Implementation
- Translated installation sequences and resource constraints into executable scheduling logic using OR-Tools CP-SAT; integrated operational-data and OPC-UA adapters, role-based access, event history, and reviewable audit records.
- Validation & handoff
- When planners requested late-part and equipment delays in their plans, extended the dependency model and scheduler; replayed historical schedule delays to validate revised behavior before release.
