Engineer wannabe designer. Passionate about innovation and new technologies.

Silvain Toromanoff

As a startup tech guy that can’t stay on the sideline any longer, I am looking for my next project around fighting climate change, ideally from Finland!

After 5 thrilling years pushing AR forward with Sayduck as CTO and cofounder, I now feel the urge to align my career with this growing personal concern.

My skills range from coding to product management and user-centric design, with a constant strive for great UX. As CTO, I not only conceived and moved forward a variety of tech services, I also led the Product Team as the company grew from 5 to 15 people. This taught me a lot about the challenges faced by startups in the early scaling phase while dealing with an ever-changing landscape. I also shaped Sayduck’s strategy, with a pivotal role in joining the 300+ Bublar family during the summer 2019.
