At IG, I’m helping evolve the Crypto trading experience, connecting high-frequency financial data with premium mobile performance. I’m focused on modular Android architecture, reliable data streaming, and a seamless experience during real-time market volatility.

At Adevinta (Kleinanzeigen), I contributed to scalable marketplace apps through TEKsystems, working with Clean Architecture, Jetpack, and Compose. At Andersen Lab, I developed Android applications, collaborated with product and engineering teams, and mentored junior developers.

Earlier, I worked on Android software for augmented reality surgical applications at PixelPlex Inc., and developed a .NET-based commercial real estate web service called OldVee. My project work also includes cryptocurrency wallets and a BLE-connected lighting control app.
