Project details
Bugs in a mobile app don't just frustrate users - they cost you ratings, reviews, and retention.
As a Flutter developer with experience across iOS and Android, I track down and fix issues that are hard to reproduce, platform-specific, or buried in state management and async logic. Whether it's a crash on a specific device, broken navigation, UI glitches, or an API failing silently - I've dealt with it. All fixes include clear documentation so your team knows what changed and why.

Mobile App Developer or Flutter Developer for HIPAA Healthcare Mobile App Development Audit
I hired Stanislav to audit our mobile app for HIPAA compliance, and honestly it was one of the smoother contracts I've had on here. He's a clear communicator, which I didn't fully appreciate until I'd worked with a few people who weren't. He actually explained things in a way our non-technical folks could follow, and he checked in regularly so I always knew where things stood.
He's very detail-oriented. He found a handful of issues we'd had no idea about, some of them fairly buried, and instead of just dumping a list of problems on us he was solution-oriented about all of it. Every issue came with a clear recommendation on how to fix it. That made him feel collaborative, like he was part of our team rather than an outside consultant ticking boxes.
He's reliable and professional in the ways that actually matter day to day. He hit the deadlines he set, responded quickly, and never made me feel like I was bothering him with questions. When something turned out to be more involved than expected, he was upfront about it and accountable for getting it sorted.
He's also committed to quality. The audit was thorough, well documented, and didn't cut corners anywhere I could see. We'll be hiring him again for the next phase, and I'd recommend him to anyone who needs careful, trustworthy work on a sensitive project.

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.

Flutter is my main stack, with 30+ Flutter projects shipped to production in the last four years. Flutter development treats mobile app performance as scope from day one. MVP mobile app development is where most projects start. App development quality matters most at MVP stage, and mobile app marketing readiness comes before launch.
Where FlutterFlow fits the early phase, I work as a FlutterFlow developer compressing timeline by ~60%. Mobile app development FlutterFlow work happens when MVP is live but the team needs a Flutter developer to ship.
