Functional demos you can click through, test with users, and show investors. Fast validation of your concept before committing to full development. RECENT WORK (2026, all live — see Portfolio section below for links and screenshots): 🌍 Tourist guide app Interactive maps, location filtering, mobile-responsive, three languages 🎥 AI decision-support tool (see the demo video in my Portfolio) Describe a decision in plain English — AI builds the alternatives out, calculates expected value, and recalculates live when you edit a number 🤝 Two-sided expert marketplace Clients post paid briefs, experts apply free, Stripe payments end-to-end — built and running real transactions 🏖️ Real-estate scoring tool Google Places data + a weighted scoring model, mapped against 30 real properties, bilingual (PT/EN) 🧪 Interactive periodic table Click any element to explore its nuclides — data-dense scientific UI, shows range beyond typical SaaS/consumer work WHO I HELP: • SaaS founders testing new feature ideas • Product teams validating UX concepts before dev investment • Enterprises evaluating technical feasibility • Startups needing investor demos quickly • Anyone who needs to see and feel an idea before building it for real MY APPROACH: Semi-retired and selectively taking on interesting projects. I'm not looking for volume - I'm looking for interesting problems that can benefit from rapid prototyping. If you need ongoing maintenance or long-term development, I'm probably not your person. But if you need to validate an idea quickly, let's talk. AVAILABILITY: Based in Ilhéus, Brazil. Available for US business hours when needed. Selective about projects - I only take work that's interesting and well-suited to rapid prototyping.

As a Manufacturing Engineer, my duties are to design not only the parts that customers need, but also, help optimize the part design, prototype the design, create detailed blueprints for manufacturing and even design the injection mold tools that will produce the parts in mass. After the design is started, I collect all information to assist with the part designing process. I create the preliminary part design then, work with the customers to make any adjustments that may be needed. Through this time I 3d print prototypes if needed to send to the client. We then have a final review to make sure the design is functioning and cost effective for manufacturing processes. Once the design is approved, I can design the injection mold tool if needed. I can help to source manufacturing and offer consulting for any questions through the entire process. For some customers I program the CNC mills and lathes in order to produce every component needed to make the parts or injection mold tools. At my full time job I work doing all of the same things from above, We design parts, and injection molds, build the molds then run them all in house. After the first run we verify all dimensions are within tolerance make any changes needed then start production. I have designed many molds that are being used for 5-10 year+ contracts making automotive parts, aerospace, military and defense, government contracts, medical etc. I have 15 years of experience in 3d modeling, concept design, part design, 3d printing and rapid prototyping, CNC programming and much more. I'm proficient in Solidworks, AutoCAD, Camworks, Fusion 360, Inventor and many other programs used to design parts. I'm taking online classes for Manufacturing Engineering at Sinclair Community College in my spare time. I have the following certifications for SolidWorks and Camworks: Associate- Mechanical Design (CSWA) Associate- Additive Manufacturing (CSWA-AM) Professional- Mechanical Design (CSWP) Professional- Advanced Mold Making (CSWP-AMM) Professional- Advanced Surfacing (CSWP-AS) Professional- Advanced Drawing Tools (CSWP-DT) 14 Camworks certifications 112 SolidWorks certifications (continuing education from 2010-present) If I can help assist in any CAD designs, product designs, CNC programming,3d printing/ prototyping, product rendering, manufacturing, sourcing, reverse engineering, injection mold design, 3d printing or anything else please reach out as I'd love to see if I can help.
