Ali Wajdan · Senior Mobile App Developer
I design, build, and ship mobile apps for iOS and Android, full lifecycle from architecture through App Store and Google Play release. Flutter is my primary tool, backed by Firebase, Supabase, Node.js backends, RevenueCat for subscriptions, and analytics and crash monitoring from day one. 5+ years of experience, 15+ shipped projects, 500,000+ combined users across fintech, healthcare, AI, blockchain, media, and construction. I work remotely with startups and enterprise clients across North America, Europe, and the Middle East.
A mobile app developer designs, builds, and ships applications that run on smartphones and tablets, covering both iOS and Android. The role spans the entire product lifecycle: defining architecture, building user interfaces, integrating APIs and cloud services, setting up CI/CD pipelines, and managing App Store and Google Play releases. In modern delivery teams, mobile developers also handle analytics instrumentation, crash monitoring, subscription billing, and incremental feature rollout. The best mobile app developers work from product outcomes backwards: they understand how mobile technical decisions connect to user retention, release velocity, and revenue.

Problem
A consumer AI startup needed a mobile app where users log dream entries and receive AI interpretations in real time. The product required three layers built simultaneously: a Flutter mobile app, a Python backend, and an AI server using OpenRouter, with streaming responses so users see the reply as it types.
Action
Architected and built all three layers: the Flutter frontend with tiered RevenueCat subscription management, a FastAPI backend handling user data and session state, and an OpenRouter AI server delivering interpretations via SSE streaming. CI/CD pipelines automated both iOS and Android releases.
Result
100,000+ users on iOS and Android since launch. The SSE streaming layer delivers AI interpretations in real time without blocking the UI thread. RevenueCat handles premium access gating with no custom payment logic required. Both iOS and Android releases run through automated CI/CD pipelines on every update.
