I am a multidisciplinary CAD and BIM professional specializing in end-to-end project delivery and workflow optimization. My expertise spans Architectural, Structural, and MEP design, ensuring that every facet of a building works together flawlessly. I don't just build models; I engineer custom solutions to make drafting and design highly efficient. Alongside advanced 3D modeling and rendering, I develop custom scripts and add-ins—such as Python and C# tools for Revit, AutoLISP routines for AutoCAD, and Ruby plugins for SketchUp—to automate complex tasks, increase precision, and drastically reduce project turnaround times. Core Capabilities: - Comprehensive BIM & CAD: Deep expertise in Revit, AutoCAD, SketchUp, and 3ds Max for architectural, structural, and MEP layouts. - Coordination & Estimation: Rigorous clash detection using Navisworks Manager and accurate model-based budget estimation. - Workflow Automation: Custom tool development (Ruby, AutoLISP, Python, C#) for tasks like automated HVAC duct routing, CAD-to-BIM wall generation, and intelligent geometry cleanup. - Visualization & Presentation: Photorealistic rendering using D5 and Enscape, paired with expert post-production and layout design in Photoshop and Illustrator.
