Raza A.

7+ years building Flutter apps that ship and stay stable. I was the sole engineer at Zing Data, a $2.4M-funded analytics startup. Owned the entire cross-platform codebase (iOS, Android, Web) serving Fortune 1000 clients across 50+ countries for 3.5 years. Here's what I actually do: Performance work most devs skip Hit 60 FPS on screens rendering live data visualizations by moving heavy computations to background isolates. Built the natural language querying layer that lets non-technical users pull insights from 120+ data sources (Snowflake, BigQuery, Postgres) without writing SQL. Architecture that scales without rewrites Designed Zing Data's codebase around Clean Architecture with Riverpod. Zero architectural rewrites over 3.5 years of continuous feature growth. That's not luck, it's planning. Fast delivery without cutting corners Built a reusable component library that cut feature delivery time by 30%. I write code other developers can actually pick up and maintain. 99%+ crash-free rate across every release. Real production complexity Firebase, Supabase, REST, WebSocket, GraphQL. I've integrated them all in production apps. Currently building a bilingual RTL deals platform for the Saudi market and a Web3 social platform with real-time chat and matchmaking. Earlier work includes analytics (Zing Data), EdTech with Arabic RTL support (Abjadiyat, Arrive), fintech (Orokii), and consumer apps (ListAIse). I work async-first from Karachi (UTC+5, 4hr overlap with US East), communicate clearly, and don't ghost mid-project. If your Flutter app needs to be fast, stable, and built by someone who's done this before, send me your requirements.
