About

I am an experienced architectural designer with many years working on residential house projects, technical drafting and 3D visualization. I specialize in AutoCAD drawings including floor plans, elevations, sections and detailed construction documents.

I also create high-quality 3D models and realistic renderings using Twinmotion, helping clients visualize their projects clearly before construction.

My focus is accuracy, attention to detail and meeting deadlines. I have worked on new house designs, renovations, remodeling projects and presentation renderings for marketing purposes.

I am available for remote freelance work worldwide and committed to delivering professional results on time and within budget.
