Syed Waleed Nawaz
Senior Mobile & Backend Lead
Background & Philosophy
I design, architect, and ship high-performance cross-platform applications — taking full ownership of state boundaries, cloud backend contracts, CI/CD pipelines, and app store releases.
With over 5+ years of specialized experience, I build cross-platform products that deliver native 60 FPS performance without cutting corners on architectural integrity or testability.
My core engineering stack combines Flutter and Dart with scalable cloud backends powered by Node.js, Firebase, Supabase, and PostgreSQL. I emphasize Clean Architecture (BLoC, GetX, Riverpod), secure database Row-Level Security (RLS), real-time WebSockets, and resilient offline synchronization.
Currently serving as Senior Flutter Developer at Health Automated LLC (UK), and formerly with ROXO (UAE) and Alright Tech, I have led engineering teams of 6+ developers and shipped 8+ production apps to the Google Play Store and Apple App Store Connect.
As a specialized Flutter Supabase developer and Flutter Agora WebRTC developer, I engineer real-time voice, video, and collaborative platforms alongside hardware-connected Flutter BLE Bluetooth integration. I also build intelligent, modern mobile experiences with OpenAI and Gemini API Flutter integration — working with clients across the US, UK, Australia, Canada, UAE and beyond to deliver scalable, enterprise-grade applications.

Technical Writing
First-hand architectural guides derived directly from designing, scaling, and deploying production mobile applications and cloud backends.
A practical guide to structuring enterprise Flutter applications using Clean Architecture and BLoC. Learn how to define explicit state boundaries, enforce repository contracts, and handle failure states gracefully.
How to design multi-tenant mobile applications in Flutter using Supabase and PostgreSQL Row-Level Security (RLS). A guide to policy modeling, tenant token claims, and repository integration.
Architectural strategies for implementing smooth, battery-efficient real-time location telemetry in Flutter using Google Maps Platform, Kalman filtering, and WebSocket streaming.
A battle-tested engineering blueprint for offline-first Flutter applications. Learn how to combine Drift SQLite, client-generated UUIDs, transactional outbox queues, and resilient cursor-based delta sync to survive flaky mobile networks.
A production-hardened engineering guide to architecting mobile subscriptions in Flutter. Learn how to combine package:in_app_purchase, Apple StoreKit 2 JWS transactions, Google Play Developer API v3, and idempotent webhook listeners into a server-authoritative entitlement engine.
A practical engineering guide to building a production-grade CI/CD pipeline for Flutter using GitHub Actions. Learn how to sign Android AABs, configure iOS code signing, manage build flavors with dart-define, automate version codes, enforce quality gates, and deliver to Firebase App Distribution and the Play Store.
An engineering blueprint for running on-device AI in Flutter. Learn how to combine Google LiteRT-LM, Gemma 2, and ONNX Runtime with INT4 quantization, manage iOS Jetsam and Android LMK memory budgets, and stream local tokens at 60 FPS without UI thread jank.
