Description

Do you have a mobile app to launch, scale, or rescue?

I'm Sabri, a senior React Native developer with 8 years of experience and over 17 large-scale professional projects — from MVPs going live to architectures that handle load.

What sets me apart: I don't just deliver screens. I understand your business constraints, I integrate quickly into your stack (NestJS, Kafka, Redis, Socket.io), and I manage the full cycle — from the first commit to App Store / Google Play deployment.

I've worked on banking applications with over 300,000 users, e-commerce platforms with over 200,000 active users, real-time chat systems, payment integrations (Stripe, Apple Pay), advanced geolocation modules, and DRM management for protected video and audio content.

You're looking for someone who delivers, not someone who explains why it takes time — we'll get along well.
