I am Gustav Friedeheim. I have a Bachelor’s degree in Scientific Programming, plus vocational training as a Mathematical-Technical Software Developer (MATSE), completed alongside my studies. As a freelance developer, I help companies optimize the automated exchange of data between their systems.
A key focus of my work is e-commerce: I connect shop systems with marketplaces such as Amazon, eBay, or TikTok Shop, with dropshipping providers and ERP systems, so that inventory, product data, and orders stay seamlessly in sync. I also implement tailored integration solutions in other industries.
What Sets Me Apart
I take initiative, actively respond to my clients’ requirements, and am always ready to take on new challenges. My strength lies in the fast, clean integration of APIs — regardless of whether the system is well-known or a niche solution. The result is solutions that are not only reliable, but also save time and costs.
Experience & Expertise
For over four years, I have implemented integrations for systems such as Shopify, Shopware, Billbee, plentyONE, and many others — tailored to each client’s system landscape and requirements.
I am also a verified Synesty partner: if you use or are considering the middleware platform Synesty Studio, I support you with introducing, building and running your integrations.
