Web & Mobile Developer React.js/Node.js, Next.js, React Native, Three.js and AI
Looking for a performant, stable, and future-proof web or mobile application?
Does your product lack visual impact, animations, or a truly engaging user experience?
Or do you want to integrate AI functionalities?
Responsive, available, and efficient, I prioritize ownership and shipping without compromising quality.
For 5 years, I've been working with SMEs, agencies, startups, and brands to create, take over, or refactor your products:
React.js, Next.js, React Native, Three.js, Node.js, TypeScript, AI,
for a robust, optimized, and scalable application.
I have developed my own SaaS products and mobile applications, and I know that great code alone is not enough. I can therefore assist you with monetization, tracking, and marketing strategies, putting code at the service of the business for:
• Your mobile application, React, Node.js, **React Native**.
• If you're building a complete SaaS with **Next.js**, Stripe, AI, and a dashboard.
• If you desire a high-endWebGL/Three.jsexperience.
• If you're integrating anAIcomponent into an existing product.
Some results:
- Conversion increase of +25% through a React-Native mobile app onboarding redesign.
- FWA Awards for The Hana Sachiko Company. x8 average traffic.
- Reduction in application weight through dataset hosting and caching. (Bundle size reduction by 3)
