01
What I built
During a service-engineering internship in Trinidad, I designed P&ID diagrams in AutoCAD for brewery automation and supported CCTV–PLC monitoring used for regulatory compliance.
The work translated pipes, valves, sensors, control logic, and human procedures into one representation that different operators could reason from.
02
Why it belongs here
A P&ID is a provenance map for a physical process. It shows where a signal comes from, which instrument transformed it, what action it can trigger, and where a failure can propagate.
The same habits now shape how I build AI systems: expose the flow, make control boundaries explicit, and never confuse a clean dashboard with a trustworthy instrument.

The missing-layer reflex
CAD and industrial automation taught me to find the layer that prevents a system from being observable or controllable, then build it. The materials changed when I moved into AI; the engineering instinct did not.
