I build BIM software that works against real IFC models, not demo files. Ten years shipping iOS and 3D products, including a LiDAR scan-to-floorplan pipeline now in production at multi-location retail chains. Recent proof: a browser 4D viewer in React and three.js, built and verified on production IFC data in one week. WHAT I BUILD IFC viewers in the browser with That Open Engine (formerly IFC.js) , openBIM workflows end to end and three.js. 4D sequencing that links Gantt schedules to model geometry. ARKit and LiDAR iOS apps that overlay BIM models on live construction sites. LiDAR capture to dimensioned floorplan. Industries this has shipped in: construction and AEC, retail operations, real estate. TRACK RECORD 2021 to 2025: core engineering team at Plinth. Photogrammetry app from first commit to enterprise deployment and App Store launch. iOS with ARKit and RealityKit, C# backend, server-side Swift with Vapor. 2025 to now: core engineer on SpaceZap, a LiDAR scan-to-floorplan product by ThinkNeural. In production at multi-location retail chains, including a major eyewear brand. Helped land their first enterprise client. 2025 to now: founder and CTO at Shivlam. Built an AR app that overlays BIM models on active construction sites, piloted with enterprise builders in India. Built the 4D browser viewer mentioned above. WHY THE DOMAIN DEPTH MATTERS I link schedule tasks to IFC objects by GlobalId, not expressID, so links survive model re-exports. If a re-export has ever broken your data, you know why this matters. Same story with point cloud noise in cluttered real spaces, ARKit drift on large sites, IFC schema quirks between authoring tools. I have hit these problems already, on shipped products. WHAT I DO NOT DO BIM modeling, CAD drafting, architectural design. I build software around your models, I do not author them. HOW TO START Send the IFC file, the scan, or the problem. I will tell you plainly whether I can solve it, and what it takes.
