About

I am a Senior CAD/BIM & Mechanical Design Specialist with extensive experience in architectural, BIM, mechanical, and product design using AutoCAD, Revit, 3ds Max, and SolidWorks.

I specialize in architectural drafting, BIM modeling, 3D visualization, mechanical and product design, 3D CAD modeling, technical drawings, construction documentation, manufacturing documentation, and design development. I can take projects from initial concepts and sketches through detailed modeling, documentation, revisions, and final delivery.

In addition to design and engineering, I have a strong background in full-stack web and mobile development. This allows me to build custom CAD/BIM automation tools, engineering applications, product configurators, dashboards, and software solutions that connect design workflows with modern technology.

My technical experience includes CAD/BIM automation, API integrations, Python, React, Node.js, databases, and custom software development. I focus on creating accurate, practical, efficient, and scalable solutions while understanding each client's requirements, technical constraints, and business goals.

I work independently and professionally, communicate clearly with clients and project teams, and pay close attention to accuracy, quality, deadlines, and long-term usability. My goal is not only to deliver the required design or software, but to provide a reliable solution that adds real value to the project.
