@vladang

Biggest risk in builds like this is usually iOS distribution friction—certificates, provisioning profiles, and TestFlight workflows breaking under poor coordination, which can stall releases even when the app itself is stable. Flutter setup would focus on a clean, modular architecture with clear separation between UI, domain, and data layers to keep features like fitness tracking scalable as the app grows. I’d implement CI/CD for automated iOS/Android builds, enforce consistent state management, and ensure reliable API integration patterns. Strong attention to TestFlight cycles and device-specific QA (especially iPhone edge cases) to prevent release regressions. Previously delivered a multi-module SaaS platform (Vue/Nuxt + API backend) with structured team workflows and stable production deployments under tight coordination. I can work for 10 hours for you before i need to rest for the day. I have all the equipment needed for cross-platform development as required. I have previous experience working in a team and if hired today Q1: How are you currently managing Flutter state architecture across your existing apps (Bloc, Riverpod, Provider, or custom)? Q2: Do you already have an established CI/CD pipeline for iOS signing and TestFlight, or should it be set up from scratch? Q3: What level of API documentation and backend stability should I expect when integrating with your fitness-related services?
