I’m Kevin Assen

I’m the maker behind Protoconcept. I help entrepreneurs, startups and companies turn an idea into a proof of concept or prototype that actually works.

Background

I’ve worked in engineering for years: on telemetry, monitoring equipment and test tooling, and on embedded systems that need to sip power and stay connected to the internet.

Building prototypes is where I most enjoy being creative: figuring out how something could work, and then actually making it.

Protoconcept is my one-person business. I do most of the work myself. When a part needs a specialist, I bring in someone from my network. You keep one point of contact: me.

How I work

  1. First, something that works

    I build the first version from loose components and hand-soldered connections. You quickly see whether the idea works, and everything is still easy to change.

  2. Test and adjust

    Together we look at what could be better. Each round I make a new version, in the model and off the 3D printer.

  3. Circuit board and enclosure

    Once the hardware is settled, I design a circuit board and an enclosure that fits around it exactly.

  4. Test and deliver

    I assemble and test everything. You get a prototype you can show, test or take further.

Also for hire

Already have a team, but missing someone for the firmware or the link to your servers? You can also hire me as a freelancer or consultant.

  • Embedded firmware

    In C, C++ and Python, with a focus on bare-metal C for low-power devices.

  • IoT infrastructure

    How data from your devices reaches a server and dashboard. From design to up and running.

  • IoT devices

    A complete device: firmware, electronics and a 3D-printed enclosure.

  • PHP back end

    Web applications and APIs in Laravel or Symfony.
