Adnan Q.

Flutter developer with 9+ years building production mobile apps for startups and growing businesses, specifically apps that handle real payments, real calls and real users. WHAT I DO BEST • Flutter / FlutterFlow apps (iOS + Android) with Firebase or Supabase backends, auth, push notifications and store deployment • Payments & fintech: Stripe (checkout, subscriptions, webhooks), wallet-style flows, transaction history, admin dashboards, secure backend validation • VoIP/SIP softphones: Linphone-based Android/iOS apps with SIP login and provisioning, dialer, call logs, push-based call wake-up, audio routing and call stability • Laravel / Node.js APIs and admin panels behind the app • AI features: chat assistants, summaries and smart search via OpenAI APIs TRACK RECORD 21 contracts on Upwork, $20K+ earned, 100% Job Success. As CTO I also built AsaanPay, a fintech payments product, so I understand payments from the product side, not just the code. HOW I WORK • Scope and milestones agreed before I start • Short delivery cycles, so you can test builds early • Clean, documented code that you own • Post-launch support available Send me a short description of your app, target platform and deadline, and I'll reply with a technical plan and a realistic estimate.
