I sell construction software to the people I used to be. Fifteen-plus years on jobsites and in the owner's chair — $490M+ in project value delivered, 600+ tradespeople led — plus a Director-of-BD track record and a founder's command of the AEC-tech stack. So buyers trust me, and demos land.

I've built it, sold it, and rolled it out: founder of Massing, an open-source IFC-native AEC platform; Director of BD at BuildingConnected owning the regional go-to-market; and the person who ran the Procore rollout that unlocked $2.5M+/month of work-in-place on a 10-year, $200M program. Today I lead a $142M museum renovation at Balfour Beatty — living daily in the exact workflows con-tech buyers evaluate.

Demo-credible where it counts: Python, SQL, and REST APIs — fluent enough to talk shop with engineers and technical buyers. Based in Phoenix, AZ, with roots in the NY metro.

A genuine in-browser BIM authoring tool + data platform spanning acquisition → turnover on one IFC model — no proprietary format, no per-seat license:

• BIM authoring + viewer — model a building from a blank IFC (walls, steel, rebar, MEP), generate a permit-ready drawing set, pre-check IBC code, and hand over LOD-500 as-built data
• GC portal — 78+ config-driven modules (RFIs, submittals, change-order chain, daily reports), 5D budget/schedule, Last-Planner board, AIA pay apps
• Development & feasibility — zoning envelope → generated IFC building + underwriting (XIRR/NPV, JV waterfall, sensitivity), disposition & appraisal
• Standards & ops — ISO 19650 CDE, Discipline Spine, Facility Condition Assessment, resilience modeling, and an MCP server so agents can drive the project
