Joao A.

I help turn ideas into real, functional products. This can start from a rough sketch, a reference photo or an early concept. I work from CAD design and 3D modelling all the way to physical prototypes. I’m new on Upwork, but I’ve been working in product design and fabrication for more than 10 years. My background includes CNC machining, thermoforming, mold-making, laser cutting and rapid prototyping with FDM and SLA. Because of this mix, I focus on designs that can actually be manufactured, assembled and used, not just models that look good on a screen. What I can help with • CAD modelling (Fusion 360 / STEP) • 3D models for printing, prototyping or presentation • STL repair, mesh cleanup and CAD conversion • Parts prepared for FDM or SLA printing • Simple mechanisms, functional parts and assemblies • Product development from idea to prototype • Prototyping and manufacturing guidance when needed How I work You can send me a sketch, a photo, a reference model or any file you already have. I’ll check feasibility and share clear options, timelines and the most efficient way to move forward. If needed, I can also print prototypes in-house and ship worldwide. Since I’m building my presence here on Upwork, I focus on clear communication, fast response and a flexible approach. If it helps, I can send a quick preview before closing any milestone. Feel free to message me with what you're working on. I’ll be glad to help.
