I build calibrated instruments for physical work — tools that turn messy field reality into unambiguous, executable decisions.

Signal As-Built Scan
Output Directive Card
Verification PASS/FAIL

The hardest part of installing complex assemblies isn’t detecting that something is off — it’s expressing the correction in a format that’s unambiguous, constrained by what’s allowed, and verifiable after adjustment.


Flagship Instrument

CALIBRATED

Directive Engine

Convert nominal ↔ as-built deltas into installer-ready directive cards (move / rotate / index), with 3D visualization and verification loops.

Instruments I Build

Directive Generation

CONSTRAINED TOLERANCED

Actionable correction steps with DOF constraints and tolerance bounds.

3D Visualization

BROWSER-FIRST LEGIBLE

Web-based viewers that make adjustments auditable and field-ready.

Verification Loops

PASS FAIL

Before/after deviation checks so teams close the gap with confidence.

Customer-facing Design Platforms

MODA

3D selection and quote-entry instruments that turn customer intent into spec-ready configurations without handoffs. Built to collapse the gap from “I want this” to “here’s the exact build + price.”

Fabricator API / Feasibility Bumpers

GRASSHOPPER

Fabrication-aware bumpers embedded in the designer workflow, flagging infeasible geometry and rerouting choices before downstream rework. Keeps exploration open while enforcing what can actually be built.

Calibration Background

Field-tested at Zahner — Built geometry pipelines, deviation analysis tools, and installer-facing interfaces for complex metal projects. Work deployed on architectural installations where RMS < 5mm matters.
