I am an Industrial Engineer and CAD designer specializing in functional product design, 3D modeling, and 3D printing–ready parts. I help startups, small businesses, and individuals transform ideas into manufacturable designs suitable for prototyping and small-batch production. My approach is engineering-driven rather than purely visual. I design with manufacturing constraints in mind, including material behavior, tolerances, part strength, and print orientation. This helps reduce iteration cycles and avoid common production issues. I have experience designing mechanical components, consumer products, enclosures, fixtures, and custom 3D-printable parts. I am comfortable working from sketches, reference products, or written requirements, and I communicate clearly throughout the project lifecycle. All work is delivered remotely with structured milestones, revision cycles, and manufacturing-ready CAD files. Makerworld account: ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒

I am a mechanical engineer specializing in SolidWorks design, reverse engineering, and advanced 3D modeling for industrial, aerospace, and product-development applications. With extensive experience across 3D printing, CNC machining, additive manufacturing workflows, and prototype development, I bring a complete design-to-production approach to each project. My work spans industrial systems design, functional mechanical components, and high-precision reverse engineering using scanning or metrology techniques. I have led multiple engineering projects, including the design and implementation of full 3D-printing laboratories and the re-engineering of mechanical parts to improve performance, manufacturability, and durability. I deliver clean, optimized SolidWorks models, detailed manufacturing drawings, assemblies, DFMA-ready designs, and solutions adapted for CNC, injection molding, metal fabrication, 3D printing, and mass-production. I focus on precision, clarity, and engineering value in every project.

I thought I will try myself as a "freelancer" to see how online engineering works, but I still have a job. :) I am a mechanical engineer and a product developer. My field of expertise is plastic part design. I have designed different plastic products (parts and assemblies) for the automotive industry (traditional mold, in-mold or overmold designs, 2K molded parts as well as in-mold film design). I also have experience in designing sheet metal parts, deep drawn or machined metal parts as they often comes with automotive products. At the beginning of my engineer carrier I created designs for food industry. It was a general design of tanks for breweries and machines for food processing firms made of stainless steel. I hope I get the chance again here. I work (and live) in Hungary, however I had/have the chance to work with foreign engineers. I have 18 years of product design experience, I use Catia V5 for my daily work, but as a freelancer I cannot afford to use it, yet. I'm curious If I had the chance to earn the money for that. :) That would be great to have my own Catia license, because with that CAD system everything is possible to be made, but it would mean higher hourly rate too. Until that, I'm going to use free CAD softwares, like FreeCAD, which looks quiet good for mechanical designs. And it can generate IGES, STP/STEP or STL files in a neutral CAD format, which is good for the client, and so the work comes cheaper too. Anyhow, let's create something from nothing!
