Nice to meet you,
my name is Marvin
A Freelance Full-Stack Product Engineer with a passion for the development of lean prototype-driven products.
For 5+ years, I have helped startups and scale-ups with my technical expertise. May it be in quickly validating their ideas through modern approaches or increasing their development speed and scale even better while acting in a cost-efficient manner.
Thanks to Marvin's expertise, we were not only able to create a modern web app with a CMS integration but also gained the know-how to successfully implement future prototypes independently.

For Scale-Ups
Scale your product
Do you want your application to perform well with a growing user base? I help you scale your product quickly from prototype to mature product through product discovery and shipping the features users actually care about.
