About Theo

Fullstack Developer React / .NET & Three.js Expert

Passionate about software architecture and immersive interfaces, I help companies create custom web applications. My expertise is based on a dual mastery of the React/Angular and .NET/Symfony ecosystems, allowing me to work on the entirety of a project. Rigorous about code quality, I apply best development and testing practices to deliver stable and sustainable solutions.

Also specializing in visual rendering, I create 3D experiences using Three.js and React Three Fiber. I can transform your Figma mockups into interactive, fluid interfaces that are faithful to your visual identity.
