What I'm looking for

I'm looking for Mid Frontend Engineer roles in Europe, on-site, hybrid, or remote, where I can build and modernize React and React Native products.

At Alex Weber Agency, I own the web and React Native admin experience for a restaurant B2B SaaS ecosystem, including restaurateur tools, waiter apps, and guest ordering and tipping flows. I've upgraded the React Native app from 0.66 to 0.82, supported the new architecture, and resolved native-bridge crashes and iOS/Android regressions.

I've refactored legacy admin flows with Redux Toolkit and reselect, migrated a web app from Create React App to Vite, and introduced TypeScript incrementally across APIs, shared state, and components. I also ship integrations and product features including maps, Firebase notifications, QR tools, analytics dashboards, drag-and-drop, PDF export, image compression, and real-time communication.

Own the admin side across web and mobile, and step into the guest web codebase when team capacity requires it. What I've done h
