Description

100% satisfied clients, and that's my pride.

Do you have a mobile app idea to launch? I'll help you turn it into a reliable, clear, and scalable product.

I'm Mennel, a developer specializing in mobile development with React Native and Expo. For 5 years, I've been assisting startups and SMEs in designing and developing custom mobile applications for iOS and Android, as well as SaaS products.

I get involved from idea to launch:

• MVP scoping and feature prioritization;

• user journey and experience design;

• React Native / Expo development for iOS and Android;

• integration of APIs, authentication, payments, and notifications;

• connection to Supabase and your business tools;

• publication on the App Store and Google Play;

• maintenance, bug fixes, and post-launch evolutions.

I can also conduct technical audits of existing mobile applications: React Native architecture, performance, technical debt, PWA, Supabase, and data security.

My goal: to help you launch a well-thought-out mobile application faster, without sacrificing technical quality. Whether you're starting with an idea, a prototype, or an already-in-production application, I bring a structured, transparent, and results-oriented approach.

5 years of mobile development, over 20 applications delivered.
