Selected engineering work
Start with the systems that shipped. Each card makes my ownership and the evidence visible before you open the full case study.
01 · Shipped in industry
Systems used around physical hardware, operators, factory workflows, and real production constraints.
Production roboticsProductive Robotics
Built the deterministic motion layer that turns planned robot paths into synchronized motor commands across two fieldbuses.
Evidence
1 kHz hybrid EtherCAT/CAN control · zero phase drift · 12+ hour autonomous operation
Production roboticsProductive Robotics
Owned the welding application from industrial communications and operator controls through seam finding and 3D perception.
Evidence
0.4 mm seam repeatability · ~1 mm mesh RMSE · major welder integration in about three weeks
Production roboticsProductive Robotics
Built the operator-facing and system software connecting real-time robot behavior to a dependable touchscreen workflow.
Evidence
100+ production features · tablet CPU reduced 50% · documentation workflow cut from three days to four hours
Factory automationGCM
Sole developer of the middleware connecting Epicor ERP to HIGHQA and automating factory-wide quality workflows.
Evidence
Six-figure system later sold to HIGHQA · roughly 300% throughput gain · about 16 hours/day automated
Computer visionGCM
Built a robotic Python/OpenCV inspection cell to replace subjective surface-defect checks with captured evidence and repeatable logic.
Evidence
Integrated robot, camera, safety enclosure, operator UI, and automated inspection reporting
Power electronicsTesla
Built automated validation infrastructure for Tesla power-electronics hardware alongside firmware and electrical engineers.
Evidence
Gen 3 Wall Connector + 52 kW DC/DC programs · TCP, UDP, HTTP, and SWC interfaces
02 · Built end to end
Founder-built products and technical projects where I owned the architecture, implementation, and evaluation.
Independent productPersonal
A phone-native intervention console for coding agents that delivers the exact blocking context instead of a generic notification.
Evidence
Claude Code, Codex, and Gemini support · X25519/AES-GCM encryption · no inbound ports
Founder-built productChangeUs
A production civic AI platform that maps plain-language concerns to the government officials responsible for them.
Evidence
Match rate moved from 0% to ~80% · LLM calls reduced ~80% · 200+ automated tests
Developer toolClausi
A developer-first compliance CLI that grounds regulatory findings in the source code being reviewed.
Evidence
Published to PyPI · full retrieval-augmented pipeline · BYOK with per-run cost estimates
Robotics researchPersonal
A physically grounded simulation and testing framework for motor plants, drivetrain friction, and cascade servo control.
Evidence
RK4 motor model · Coulomb/Stribeck/viscous friction · position/velocity/current control loops
