Hire the Best Engineering Freelancers
in Serbia

I help homeowners, contractors, and architecture studios turn unclear or incomplete building information into coordinated, build-ready architectural and engineering documentation — so projects can move forward without delays, redesigns, or on-site confusion. I work on residential and commercial projects where accuracy, coordination, and constructability are critical — especially during renovations, upgrades, permit preparation, and construction planning phases. Typical projects I support include: 1. Renovation & As-Built Drawings – Accurate existing-condition documentation and proposed layouts used as a reliable design baseline. 2. Architectural & Permit Documentation – Clear, authority-ready plans prepared for approvals and contractor execution. 3. BIM & 3D Modeling – ArchiCAD / Revit models for coordination, visualization, and clash-free workflows. 4. Structural Drawings & Engineering Support – Practical, code-aware structural solutions aligned with the architectural design. 5. 2D CAD Production & Drawing Cleanup – Organized, consistent, and construction-ready drawing sets. As a Top Rated freelancer with 40+ international projects completed, my focus is on delivering documentation that reduces revisions, prevents misunderstandings on site, and supports smooth execution across design and construction teams. If you already have sketches, existing drawings, or early concepts, I can help structure them into a clear, coordinated, and construction-ready set. If your project is still at an early idea stage, that’s completely fine. I regularly work with clients starting from initial concepts and help define a clear, structured path toward design and documentation. Send me a short description of your project, and I’ll let you know the most efficient next steps.
