Hire the Best Product Developers
in Poland

Selected experience: Bang & Olufsen, Design Storz, ÖSWAG Werft, RUF Porsche Automobile Hi, I'm Michał - an Industrial Designer focused on developing physical products from research and concept to CAD, prototyping, and design for manufacturing. I help startups and product companies turn ideas into functional, well-resolved products, combining technical problem-solving with a strong sense of form, proportion, and aesthetics. Top Rated Plus on Upwork, with 600+ hours spent on long-term physical product development projects. My work is best suited to design-led physical products where appearance, usability, CAD, prototyping, and manufacturing awareness need to come together. I usually look at new product projects through four areas: form, use, build, and make - so the product direction is clear before too much time is spent on detailed CAD. This includes consumer products, drinkware, bottles, containers, lighting, lifestyle objects, ergonomic products, mobility-related concepts, vehicle interior components, drone exteriors, enclosures, and products with light mechanisms or practical constraints. I can support projects through: Research and product direction Concept sketches and form development Industrial design and 3D CAD modelling Prototyping and 3D printing Design for manufacturing Product refinement before production Visualisation and presentation materials I regularly work with Rhino, Fusion 360, SolidWorks, Blender, 3ds Max, Alias, and KeyShot. Depending on the project, I can also support material selection, component integration, prototype testing, supplier communication, and production-focused CAD refinement. My background includes industrial design studies in Kraków, mobility design at FH Joanneum in Graz, experience at Design Storz, and product work connected with Bang & Olufsen and ÖSWAG Werft. One of my strongest studio projects was a police boat concept for an Austrian shipyard, which was selected and built. If you are developing a physical product and need someone who can connect research, form, CAD, prototyping, and practical product development, feel free to send me a message.

Product Engineer, Ex-Founder and product Developer with 7+ Years experience A quick cheatsheet for all you need to about me: my professional experience actually started as a content creator it lasted 5 years and 200k Subscribers on YouTube by 2019 I decided to follow a new path and I started my software engineering bachelors degree in Istanbul fast forward a couple of years and I got a 2nd bachelor in computer Science in Poland, during that time I've worked for companies from international corporations to startups and from development to product management, project management, Designer, Sales and marketing, even founded 2 companies 1 of which got accredited in the European AI awards last year. Moving onto the elephant in the room and the question I get asked the most, With all your experience why are you here? answer is straightforward I am an workaholic I average 100 hours work days and if I'm not working with a client I will probably be working on one of my side projects. Moving on to my Work Experience: - Founding Engineer At Kindssecurity - AI Engineer WorkHive - Product Engineer Promoted to Product Lead At LightworkAI - CTO At Vindey - Head Of Product & AI At Kiiwi.ai

I extract data that isn't meant to be extracted, and hand it back as something you can use the same day: a clean spreadsheet, a queryable database, a report that refreshes itself. What's different about how I work now is the toolchain. Most of the pipeline runs itself, so the first version of your output usually lands within hours, not at the end of the week. Before you commit to the full job you get a real sample - actual rows from your actual source, not a promise. And if a source can't be extracted cleanly, you hear that from me instead of paying me to find out. Where LLMs earn their place, they sit inside the pipeline: pulling structured fields out of messy PDFs and scans, classifying and enriching records at volume, flagging the rows a human should check. Where they don't earn it, it's plain Python. I'll tell you which is which rather than selling you the word "AI". Track record here: 51 jobs, 1,000+ hours, $40k+ earned. The largest was a three-year contract delivering weekly extraction runs, 1,011 hours, without a missed delivery. Stack: Python, Scrapy, Playwright, pandas, SQL. Excel with VBA or Power Query when your team lives in Excel and has to maintain it after I'm gone. Everything in writing, no calls needed. Send me a URL or a file and you'll get a straight answer on what's extractable, what isn't, and what it costs.
