React.js/Node.js | React Native | Three.js & AI Web & Mobile Developer
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 are you looking to integrate AI functionalities?
Responsive, available, and efficient, I prioritize ownership and shipping without compromising quality.
For the past 5 years, I've been working with SMEs, agencies, startups, and brands to create, take over, or refactor your products using:
React.js, Next.js, React Native, Three.js, Node.js, TypeScript, AI,
to build robust, optimized, and scalable applications.
I've developed my own SaaS products and mobile apps, and I know that great code alone isn't enough. I can also assist you with monetization, tracking, and marketing strategies to align code with business objectives for:
• Your mobile application using 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:
- Increased conversion by +25% through a redesign of the onboarding process for a React-Native mobile app.
- FWA Awards for The Hana Sachiko Company. 8x increase in average traffic.
- Reduced application weight through dataset hosting and caching. (3x reduction in bundle size)
