With a deep understanding of the full software development lifecycle and an extensive background in building cross-platform mobile and web apps, I am confident that I would be the perfect fit for your AI-powered product. Throughout my 8+ years of experience stooped in prestigious firms like Apple and Amazon, I've gained remarkable insights into how large organizations shepherd projects from conception to fruition. This has honed my ability to foresee pitfalls, manage scope creep, and address potential technical debt ahead of time. An efficient coder is incomplete without empathetic communication skills which is why I pride myself on my transparency even when it's not always in line with your expectations. My goal isn't just to write clean, maintainable codes but to build sustainable solutions that actually drive results. This philosophy has not only earned me loyal clients but also saved them unprecedented weeks of avoidable rework. In terms of technical chops, I boast a versatile repertoire from AI integrations to code revamps/upgrades to building impeccable cross-platform mobile apps with Flutter, React Native et al and full-stack web apps powered by LLMs like OpenAI and Gemini. Besides these core functionalities, my expertise extends to developing robust AI workflow automations that have consistently saved teams several precious hours week after week.

I've architected and shipped cross-platform SaaS mobile apps with Cordova/Capacitor, so this is right in my wheelhouse. Core idea ingestion, then I’ll set up the shared codebase in Ionic/React Native, handle platform-specific bridges for iOS/Android, and integrate PHP backend services via REST. Frontend will be responsive with CSS modules and service workers for offline caching. Validate with Jest and Detox, then deploy via Fastlane. No unnecessary features, just clean separation between UI, business logic, and persistence. Thanks, Andrii.

A co-creator that turns a core idea into a real, cross-platform app build. I’ll translate your chat-supplied concept into a clear product scope, define screens and user flows, and map features into an implementation plan. Then I’ll deliver clean, maintainable code for iOS and Android from a shared codebase, with practical state management and API-ready architecture so the app can grow beyond the first release. If you’re starting with “the core idea in chat,” I’ll help structure it into requirements fast, ensuring the first milestone produces a working prototype, not just notes. The result: a usable app foundation that’s testable, extendable, and ready for iteration.

Hello, "Hybrid Flutter App With Shared Codebase" - turning your core idea into a full mobile app I’ll use Flutter to write one codebase for iOS and Android, letting us ship fast and keep maintenance low – Flutter’s hot‑reload speeds up UI tweaks. I automated a similar Reolink backup: https://www.freelancer.com/projects/automation/Automate-Reolink-Video-Backup-Script/reviews If you need real‑time sync across devices, I can add Firebase for instant data sharing and offline support. Do you have a preferred backend (e.g., Node.js, Firebase) for the app’s API? Looking forward to working with you. Artur Giżycki
