At Petleo GmbH, I contribute to Flutter mobile and web applications across the Petleo ecosystem, from feature delivery through production releases. I designed and developed the Purina marketplace and Trupanion pet insurance integrations.

Previously, I developed SuperApp modules at KOBIL GmbH and e-wallet and e-payment features at AHLPay, including NFC and face recognition integrations. I also built Numberloo, an interactive social polling app published on the App Store and Google Play, and restaurant ordering features for Chex.
