Mobile developer with 14 years experience, 80+ shipped apps and more than 1M+ downloads. If you're starting a Flutter app from scratch, I take it from concept to the App Store. If your iOS or Android app has stalled, I get it shipping again. If a previous mobile app developer missed what you actually needed, that's where I usually come in. 𝗪𝗵𝗮𝘁 𝘆𝗼𝘂 𝗴𝗲𝘁 I work primarily in Flutter for smartphone apps, with native iOS and Android experience dating back to 2012. When backend or AI work is heavy, Python and Node.js handle it. Mobile app design happens early by a dedicated mobile app designer. 𝗪𝗵𝗮𝘁 𝟴𝟬+ 𝗮𝗽𝗽𝘀 𝘁𝗮𝘂𝗴𝗵𝘁 𝗺𝗲 Mobile app development starts with understanding the problem the product solves. A Flutter developer worth hiring flags problems before they become rebuilds. A few projects I've shipped as a mobile app developer: - Patient Gateway (UK) - Flutter app for medical transport with Firebase sync - Rheo (Switzerland) - Flutter app and PWA for vital signs via BLE biosensor - Inne Minilab (Germany) - fertility tracking with IoT BLE biosensor - ClosetBee (US) - Flutter AI wardrobe app, the kind of work I take on as an AI mobile app developer - MoveOn (Israel) - eco taxi app with route planning and payments - Warehouse App Set (UK, NDA) - 5 native apps for inventory and dispatch 𝗜𝗻𝗱𝘂𝘀𝘁𝗿𝗶𝗲𝘀 Healthcare, logistics, transportation, lifestyle, internal tools, AI integrations, fintech, travel, education. If you're looking for a mobile application developer or Flutter developer who thinks past the spec, that's the work I do. I've had clients reach out a year into a project after hiring the wrong mobile app developer first. Early hire saves months. Send a message with what you're building and I'll give a scope estimate and the first technical decision I'd want to settle.
