I solve problems and build better machines with mechanical design, hydraulics and automation. Since January 2020: cut lists for steel buildings, then the assembly floor, then nearly three years drafting in CAD. Now I’m Lead Engineer and Project Coordinator at New Heights, the company behind Equipter. I also build internal tools and agentic AI workflows for team projects.

– present · 6 yr 3 mosince

Lead Engineer and Project Coordinator

– present · 3 yr 2 mosince

My work centers on mechanical design and project coordination: I coordinate design updates and lead change initiatives across all product lines, including generation release updates for the 7000, the Tow-A-Lift and older models. I also manage control systems and integration, and I develop internal tools and create agentic AI workflows for team projects.

Engineering Draftsman

– · 2 yr 9 mo

I drafted detailed CAD components for new products, with precision and clarity in every drawing. I raised quality standards for parts and assemblies, managed CAD model changes, and carried those changes into production.

Assembly Technician

– · 4 mo

I assembled mobile machinery and welded chassis and components on the manufacturing floor, the hands-on foundation for my drafting and engineering roles.

Scenic Ridge Company

– · 7 mo

Detailer / Drafter

– · 7 mo

I created detailed material cut lists for commercial steel building projects, keeping quotes accurate and efficient, and improved the process for estimating concrete and rebar quantities for building foundations.

The story behind these four lines is below. Read the long version

The long version

Four jobs, in the order I had them, each with a drawing from that work. Every view adds a layer of the same language: a list, a symbol, a sheet, a system.

Fig. 3 · Your scroll wheel is the input shaft. An 18-tooth gear drives a 36; an 18 on the same shaft drives a 54. That’s 6.00 : 1 through two external meshes, so the output turns the same way as the input, six times slower.

List it.

I started in January 2020 at Scenic Ridge, on buildings rather than machines. Before any steel gets cut, someone has to count every piece: its shape and its length. I made those cut lists for commercial steel buildings, and improved how we estimated the concrete and rebar for the foundations underneath.

Weld it.

In August 2020 I joined New Heights, the company behind Equipter, as an Assembly Technician. For four months I assembled mobile machinery and welded chassis and components on the manufacturing floor. It’s where I learned how machines actually go together, and it’s the foundation for the drafting and engineering that came next.

Draw it.

Four months later I was promoted to Engineering Draftsman, and spent nearly three years drafting: detailed CAD components for new products, and the model changes that carried them into production.

Good drawings don’t get replaced. They get revised. Watch this one change.

Bring it together.

In September 2023 I was promoted to Lead Engineer and Project Coordinator. Most of my work is mechanical design and project coordination: design updates and change initiatives across all product lines, from concept through prototype to production. I also manage control systems and integration, where the mechanical, hydraulic and software sides of a machine have to agree.

Here’s one change, followed from the first sign of trouble to the next generation release. Step through it and watch the model, the drawing, the weekly BOM change list and purchasing move together.

INVENTED CHANGE · GENERIC BOOM HEAD

Fig. 7, a change followed throughSide view of a generic telehandler boom head. The fly section comes out of the outer section and its collar; the head welded to its end drops below the boom as a heel that tapers to the carriage pivot. A tilt cylinder runs down the back of the heel from a clevis bracket to a linkage under it: idler links pinned through the heel and tilt links to the carriage. The fork carriage hangs from the pivot with a hooked fork, and a tilt sensor sits on its mounting plate. The change adds a doubler plate round the carriage ear that carries the tilt-link pin; an inset shows the carriage weldment drawing at revision C, and a ruler along the bottom marks concept, prototype, production and generation release.EAR FLEXES · ADD DOUBLER?NEW · DOUBLER PLATE, EAR (2×)WK-2120 · CARRIAGE WELDMENTCREV · CHANGEB · RELEASEDC · ADD DOUBLERSZONE B2CONCEPTPROTOTYPEPRODUCTIONGEN.

Concept. Prototype testing shows the carriage ear that carries the tilt-link pin flexing under load. A doubler plate around the pin bore is sketched as the fix.Prototype. The doubler is modeled, checked for clearance with the tilt links through the full tilt range, and welded onto the prototype carriage for a retest.Prototype. The weldment drawing goes to rev C: a revision cloud, a delta and a new line in the revision block. The doubler gets its own part drawing.Production. This week’s release goes to purchasing with a BOM change list: one new part, one revised weldment. Nothing waits for the full package.Production. Purchasing orders the doublers from the change list the same week, and the record shows them ordered.Generation release. The parts are received and the change ships in the next generation update, with every step on record.

Integration is the smaller share. One slice of it, in one figure: press a control, a valve shifts, oil flows, and the steel moves. Hold Raise or Lower.

ILLUSTRATIVE CIRCUIT · NOT ANY PRODUCT’S SCHEMATIC

A counterbalance valve with an integral check valve is mounted on its cap-side port; its pilot comes from the rod-side line. In the center, an open-center 4/3 solenoid valve, spring centered, with solenoid S1 on the left and S2 on the right. At the bottom left, a fixed-displacement pump driven by an engine shaft, a relief valve, a pressure gauge, a return filter and a vented reservoir.

Retracting runs faster than extending at the same pump flow, and pushes more oil back to tank than the pump delivers, because the rod side has less area.

Machines I’ve collaborated on

Two towable machines I’ve worked on at New Heights, with design work and project coordination on different aspects of each, from concept through production. The specs are Equipter’s published figures, shown for scale: they describe the machines, not my part in them.

Case study

Workbench · parts list · tools and workflows

Workbench: See that boom at the top of the page? The first tool here figures out whether it stays standing.

When I’m not designing machines, I build internal tools and AI workflows, usually working alongside AI coding agents. These tools are private, so exact details aren’t shared.

Item 01

REAL-TIME STABILITY ENGINE

PRIVATE C · TYPESCRIPT · ELECTRON

I built the backend: a real-time physics engine that monitors and controls load and machine stability. From the boom’s pose, the load and the slope of the ground, it solves the machine’s moment balance in three dimensions, works out how close it is to tipping, and develops the load chart automatically.

Item 02

DESIGN-TO-PURCHASING HANDOFF

PRIVATE WEEKLY AGENTIC WORKFLOW · CLAUDE

I set up an agentic workflow that releases parts to purchasing every week instead of in one package at the end. Manufacturing starts on each part as soon as it’s released, which compresses a project’s timeline from idea to finished machine. Each week the agent compares the release with the last, hands purchasing an ERP-ready BOM change list and keeps every component’s status in one place.

Item 03

ENGINEERING STANDARDS REFERENCE

PRIVATE PREACT · VITE

An engineering reference for the team: bend, torque and drawing standards in one place, every value traced to its source and status, built to open beside the model in Onshape.
