You will get a functional prototype to test your ideas fast
Project details
I create functional, demo-ready prototypes that help founders and teams validate ideas quickly without the burden of production engineering. With over 10 years in B2B product development across European companies, I combine product thinking with hands-on building.
What you’ll receive (depending on tier): a functioning web prototype (1–5 pages), a live demo link, source code, and a brief walkthrough. I keep the process straightforward: quick scope confirmation, progress checkpoints, and then delivery to ensure we stay aligned and move quickly.

About Robin
Functional Prototype & PoC Developer for (SaaS) Founders
Hilversum, Netherlands - 6:17 pm local time
My background is in product management across B2B software, where I’ve worked at the intersection of technology, business, design, and stakeholder management. That means I don’t just build what is requested, but I work to understand what actually needs to be solved, what should be tested first, and what will create the most value.
I specialize in functional prototypes, PoCs, and validation builds: software that helps you test an idea, demonstrate a concept, or make a workflow real enough to learn from. I’m especially strong at translating rough ideas into concrete, useful, and demo-ready results.
What I bring is a mix of product thinking and hands-on building. I can think through the value proposition, user flow, technical shape, and practical trade-offs needed to create something that is not only functional but meaningful. My goal is always to help clients get further than they expected, not just with a deliverable, but with clarity, momentum, and better decisions.
Outside of work, I enjoy hiking, bikepacking, chess, and building things in general. I’m based in the Netherlands.
Steps for completing your project
After purchasing the project, send requirements so Robin can start the project.
Delivery time starts when Robin receives requirements from you.
Robin works on your project following the steps below.
Revisions may occur after the delivery date.
Confirm scope & success criteria
We align on goal, user flow, and what “done” means.
Build + quick checkpoints
I share 1–2 progress check-ins to confirm direction before final delivery. Those are not revisions; I work in smaller increments to prevent me from making assumptions. While using it, you might also see behaviour you didn't know would happen.
