Product Developer

I have the coolest education in the world - Software Developer. With 10+ years in the industry as an employer, employee, freelancer, consultant, and entrepreneur, I've covered a range of exciting roles, including senior developer (agentic and otherwise), architect, infrastructure specialist, cloud engineer, and automation engineer. When my fingers aren't flying over the keyboard, diving into the creative world of digital craftsmanship, I am out on the sea enjoying kitesurfing with my fellow surfers, photographing nature and scenic landscapes, reading tons of fantasy or delving into my hobby as an amateur game developer.

He combined that promise with a great personality that made collaboration a breeze. Simon applied both a self-starting as well as a collaborative mindset to the product he helped build. While corona times made remote work the norm, Simon's efforts made this a seamless experience.
