Description

Mobile Developer | React Native | Expo | TypeScript ✨

Did your mobile app, initially built quickly as an MVP, low-code, or no-code solution, now reach its limits in terms of performance, stability, user experience, or maintainability?

I step in to take over an existing application or develop a robust mobile product with a modern stack based on React Native, Expo, and TypeScript.

My goal: transform your application into a reliable, scalable product ready for growth, both technically and product-wise.

With 4 years of experience as a developer, I have worked in various contexts:

Startups
Agencies
SMEs
Products undergoing significant evolution

This diversity allows me to quickly adapt to your working methods, understand your business challenges, and deliver concrete, user-oriented solutions.

I have contributed to the development of various mobile projects in React Native:

iOS & Android mobile applications
Mobile SaaS applications
Dashboards and business tools
Applications connected to complex APIs
Redesign and optimization of existing applications
Publication on the App Store and Play Store

My approach is turnkey:

a professional, stable, documented, and scalable product, without technical debt that forces you to fix the same problems with each iteration.

Technical Stack:

React Native, Expo, TypeScript, JavaScript, React Query, Zustand, Redux, NativeWind / Tailwind, Shadcn, Material UI, REST / GraphQL API, Supabase, Firebase, Prisma, Stripe, Mobile CI/CD…

Are you looking to launch a mobile application, redesign an existing MVP, or strengthen your mobile team with an experienced React Native developer?
