Built for real operations — here's one
A machine shop's whole work-tracking system
A machine shop needed to know a simple thing that no off-the-shelf product would tell it: where does the shop's time actually go? Orders moved through the floor on paper and memory; productivity was a feeling, not a number.
The tool I built became the shop's operating rhythm. Workers badge in and out of jobs with a barcode scan — no keyboards on the floor, no forms. The system keeps the order log, generates the packing slips, and turns the scans into reporting the owner actually wanted: a 15-minute-interval heatmap of worker activity showing exactly where the day went, plus order and task views for the office.
It was run like a product, not a favor: versioned releases, each with a written change log, planned features tracked and delivered, and the edge cases of a real floor handled — like workers forgetting to badge out of one task before starting the next.
Requirements gathered from the shop floor, built against the real order log, iterated on operator feedback after delivery. That lifecycle — not the code — is the product.
Same discipline, different operations
New Patient Tracker
Tracks new patients from first contact through scheduling — with referral-source analytics, so the practice could finally see which channels actually produce patients. Automated email notifications included.
Released, upgraded and documented like a productContracting Calculator
Manages negotiated insurance rates across carriers, built directly against the practice's master fee schedule — the rules that lived in the contracting manager's head, made checkable.
Iterated on documented client feedback after deliveryCopay Calculator
Estimates a patient's procedure cost by procedure code and payer, using the real allowable schedules — an answer at the front desk instead of a callback.
Multiple fee-schedule revisions carried through productionPayment Estimator
Patient payment estimation at the point of service — what will this cost me, answered before the visit instead of on the bill.
Release notes and operational documentation shipped with itLab Results Portal
A web portal giving a clinical lab's clients direct access to their results — replacing manual result distribution with self-service delivery.
Public-facing · ran the lab's daily result deliveryClosed-loop climate controller
A controller that chases the correct variable (vapor-pressure deficit, a moving target), with dual-band hysteresis across coupled heater/humidifier loops and fail-safe-off on stale sensor data — the rules an expert grower holds in their head, encoded and running unattended.
