Steffen Giebler is a solo founder and software developer based in Berlin Mitte, Germany, working under the studio name 52N34S Group. He builds and ships his own mobile and web applications, and works with founders to turn early ideas into production products. His own products are: Orivela, a personal records vault for iOS and Android that stores documents, contracts and subscriptions and answers questions about them in plain language. Kolibi, an AI photo calorie tracker for iOS and Android that reads a meal from a single photo. Peeranimo, a peer-matching social platform on the web that connects people who are in the same chapter of life. Carpincho, a Spanish learning app focused on 1,000 high-frequency words in Rioplatense, neutral Latin American and Spanish variants, live on the App Store. ErdiKnows, a web app for developers that puts deploys, releases and incidents as markers on the same timeline as product metrics, so a drop can be read together with what shipped around it. It is not an analytics tool — it is the layer on top. He has built more than ten platforms, both self-founded and for clients, and is available for freelance product development, software architecture and long-term product partnerships.
