Selected work

Six engagements, described as far as confidentiality allows.

Client identities are withheld by default. The methods and the measured results are not — those are the only part of a case study worth reading anyway. Full documentation, including drawings, raw time studies, and deliverables, is available under mutual NDA.

Heavy-duty remanufacturing Case 01

Cutting 38% off a reman line's cycle time

Station-by-station time study of a diesel aftertreatment remanufacturing operation, with an engineered and costed fix for every loss identified.

Utility & industrial automation Case 04

Automating protection-system monitoring on an SEL RTAC

Controller logic that continuously polls protective relays, verifies their settings, and surfaces device health and misoperations — bridging DNP3, Modbus, and IEC 61850 GOOSE.

Capital planning & simulation Case 05

Proving a line change in simulation before the spend

A discrete-event model loaded with real station timing and variance, used to find the true constraint and test changes in software before a dollar of capital is committed.

Also in the portfolio, not written up here: a V6 engine teardown and rebuild process sheet covering 67 operations with torque specifications, fastener callouts, and part-number control; an automated blast cell conversion package; and ergonomic assessment work using hypothesis testing against published population strength and dexterity norms. These are available under NDA.
