Who I am
Arbab Naseer is a software engineer and mobile app developer who specialises in cross-platform development with React Native (Expo) and Flutter. Since 2022 he has built iOS and Android apps for agencies, startups and product companies, and he currently works remotely as the React Native developer on Stadioss, a sports social network on the App Store.
His work covers the full front of a product (interface, custom components, API integration, state management, performance and store releases) and extends to full-stack web development with React, Next.js, Firebase and Node.js when a product also needs a website or admin panel.
What I can do for you

Mobile app development
Cross-platform iOS and Android apps in React Native or Flutter, from Figma to a published App Store and Google Play listing.

How I work
- step_1
Understand
We agree on the problem, the users and what done looks like before anyone writes code.
- step_2
Plan
I break the work into small, shippable milestones so you see progress every week.
- step_3
Build
Clean, typed, reusable code with as few third-party packages as the job allows.
- step_4
Ship & support
Store submission, release notes and fixes after launch. I don't disappear on release day.
