About Paul

I work as a freelancer on short-term embedded systems development missions. To do this, I created my company Emsyx (EURL) and have already successfully completed a first mission with the company ACRN based in Rouen.

Contractually, I offer my services either on a daily basis (régie) or on a fixed-price basis (results-oriented).

I implement solutions quickly to:
  • fix critical bugs in your existing products.
  • prototype complete embedded systems (software + electronics based on an evaluation board and simple electronic routing + test environment).
  • support a team during a difficult project phase (delivery).

For any quote requests, feel free to contact me via Malt or email [].
