Architecture Before Packages
I define strict state ownership, domain boundaries, failure handling, and backend contracts before choosing packages.
Senior Flutter & Mobile Backend Engineer
I am Syed Waleed Nawaz, a Senior Flutter Developer and Mobile Backend Engineer based in Pakistan, architecting cross-platform applications across Android, iOS, Web, and Desktop for clients worldwide.
6+ years designing, architecting, and deploying high-performance cross-platform applications — backed by scalable cloud infrastructures.
I specialize in Flutter, Dart, Firebase, Supabase, Node.js, REST APIs, WebSockets, and PostgreSQL. In my projects, engineering does not end at the UI layer: database security policies (PostgreSQL RLS), payment gateway integrations (Stripe, PayPal), real-time streaming, offline-first caching (Hive, SQLite), and store releases are all owned end-to-end.
My background includes leadership roles where I have implemented Clean Architecture standards, managed CI/CD release pipelines via GitHub Actions, and overseen app store approval processes. I have collaborated remotely with cross-functional product and engineering teams in the UK, UAE, and Pakistan.
The systems I build include enterprise healthcare platforms, multi-tenant SaaS tools, food delivery ecosystems, crypto trading interfaces, and AI content assistants.
How I Approach Development
Production States Are Product States
Loading, offline caching, retry with backoff, permissions, expired JWTs, and provider errors are treated as first-class product states.
Intentional Cross-Platform Composition
Shared business and state logic is maximized, while navigation, layout, input modes, and platform APIs receive dedicated platform polish.
Release Is Part of Engineering
CI/CD automation, Google Play Console tracks, and Apple App Store Connect provisioning are integral parts of the delivery lifecycle.
