About Me

Thennarasan Selvaraj

BIM Professional & Digital Workflow Innovator

I bridge the physical and digital worlds of construction. My journey began with creating 3D models and evolved into a passion for optimizing the entire process behind them—through leadership, automation, and R&D.

With 9+ years of comprehensive experience, I specialize in high-accuracy Scan-to-BIM workflows, BIM automation (Dynamo, Revit API), and multi-disciplinary coordination for large-scale infrastructure, hospitality, and residential projects.
