Flutter App Developer | iOS & Android | APIs & Hardware Integrations

I’m a Flutter Mobile App Developer building production-ready apps for iOS and Android, especially products where the difficult part is more than just the UI — API integrations, GPS and live tracking, OBD/hardware connectivity, video calling, payments, subscriptions, AI features, localization, and custom backend systems. I work on both new Flutter app development and existing applications that need bug fixing, refactoring, performance improvements, new features, or production support. My focus is on building apps that remain reliable once real users, real devices, and real-world edge cases are involved. Projects delivered by our team include: Mastertronic — an automotive mobile app that connects with OBD hardware for vehicle diagnostics and performance measurement, including vehicle-data processing and hardware-to-app communication. Konsilmed — a telemedicine mobile app with doctor-patient workflows, video consultations, and multilingual/localized user experiences. EduSafeGo — a location-based application involving GPS, maps, live location tracking, and role-based workflows. SamaritanCalls — a production calling and communication app where reliable call flows and mobile behavior are an important part of the product. Carzify — a marketplace platform involving search, location-based functionality, APIs, multiple user roles, and centralized administration. EasyPlan — a workforce and production-management system built around planning, operational workflows, users, and centralized business processes. This experience means I’m comfortable with mobile apps that need to communicate with more than a simple backend. That may be an external hardware device, a real-time service, maps and location APIs, payment providers, AI services, or a custom backend. I can help with: - Flutter & Dart development for iOS and Android - Existing Flutter app debugging, refactoring, and optimization - REST API and third-party API integration - OBD and hardware integrations - GPS, Google Maps, navigation, and live tracking - Video calling and real-time communication - Firebase, authentication, push notifications, and cloud services - Payments, subscriptions, and in-app access - Python / FastAPI backend development - AI / LLM integrations for mobile applications - Multilingual apps and localization - App Store and Google Play deployment - QA, production support, and ongoing mobile app development For larger projects, I work with my development team across mobile, backend, QA, and deployment, while I stay directly involved in the architecture, technical decisions, client communication, reviews, and delivery. You still have one point of contact throughout the project. I also pay attention to what happens after launch: maintainable code, reliable integrations, clear error handling, production debugging, and a codebase that can grow without becoming difficult to manage. If you already have a Figma design, product specification, API documentation, existing Flutter codebase, or a live mobile app that needs work, send it over. I can review the technical side first and give you a practical development approach before we start.
