React Native, TypeScript Developer for Task Management MVP App (iOS & Android)
Faraz is probably the best communicator we've ever worked with in terms of inviting a third party contractor into our workflow, which we've done many times. His fluency in English is great. He's extremely reliable for daily and also throughout the day updates on movement which helps create a very collaborative workflow therefore getting the tasks done faster with everyone in the loop. He's also extremely optimistic which our startup environment loves. He has a "anything that can be done will be done" attitude even if he doesn't know the exact path at that moment. In essence he's extremely resourceful even when thrown in the deep end and takes on any challenge.
Would highly recommend to any company looking for a spirited talented developer.

Are you tired of slow apps, poor UI, crashes, or developers who don’t understand your vision?

Whether you need a new app, want to fix bugs, improve performance, or add features like push notifications, deep linking, or live updates — I provide complete end-to-end solutions.
I focus on clean architecture (MVVM), strong state management, optimized performance, and powerful backend integration (Firebase, Node.js, REST APIs, WebSockets) so your app delivers real value and scales easily.
