Hire the Best Flutter Developers in Islamabad, PK

Top Rated Flutter developer and AI voice agent builder with a 100% Job Success Score. I build two things at an expert level: production Flutter mobile apps for iOS and Android, and custom AI voice agents using Deepgram, ElevenLabs, Twilio, and Cartesia. Both involve shipping real products that work in the hands of real users, not demos. On the mobile side, I have 10+ apps live on the App Store across health, fintech, productivity, and AI categories, all built solo from architecture to App Store submission. Every app is downloadable and verifiable before you hire me. My stack is Flutter and Dart with Riverpod or BLoC for state management, Drift and SQLite for offline-first local persistence, Firebase for backend, RevenueCat for subscription paywalls and in-app purchases, and HealthKit for iOS health data integration. I also build native Swift extensions including WidgetKit home screen and lock screen widgets with bidirectional data sync via App Groups, which most Flutter developers have never touched. On the AI voice agent side, I build custom telephony pipelines from scratch without relying on Vapi or Retell as a middleman. My production stack uses Deepgram for real-time speech to text with sub-300ms latency, ElevenLabs or Cartesia for natural-sounding voice synthesis, and Twilio for call routing and phone number management. I have built inbound and outbound AI calling agents, AI receptionist systems, lead qualification agents, and appointment booking flows. Backend orchestration runs on FastAPI or Python, with Firebase or Supabase for logging and GoHighLevel, HubSpot, or Airtable for CRM integration. The client owns every component, every credential, and every line of code. Beyond mobile and voice, I build automation workflows using n8n, Make, and Zapier, and integrate LLM layers using OpenAI GPT-4, Claude, and Gemini for conversational logic, RAG pipelines, document processing, and AI coaching systems. Core skills across both verticals: Flutter, Dart, Swift, Firebase, RevenueCat, Riverpod, BLoC, HealthKit, WidgetKit, App Store Submission, Twilio, Deepgram, ElevenLabs, Cartesia, Python, FastAPI, OpenAI, Gemini, Claude, n8n, REST APIs, WebSockets, RAG, Supabase, Airtable, GoHighLevel. What stays consistent: clean architecture, clear communication, and delivery without hand-holding. I do not disappear mid-project and I do not need the same thing explained twice. If you are building a Flutter app, an AI voice agent, or a system that combines both, send me a message and tell me what you are working on.
