Experience

RIPE Rainbow

https://github.com/ripe-tech/ripe-rainbow/
RIPE Rainbow is an automated testing tool for web and mobile applications that can be used by people with no programming experience, making it possible for functional testers to translate their scripts into automated code.

Feedzai Pulse

Feedzai Pulse is a platform that helps users to easily deploy data science models into production through an extensible distributed system. This system is capable of processing data in real-time and is primarily used for fraud detection in electronic payments.

RIPE Components | Vue.js

https://github.com/ripe-tech/ripe-components-vue
I built a UI kit that was designed to be used in Platforme's back-office applications, maintaining a coherent design system. It's the equivalent to well-known tools such as Twitter's Bootstrap and was built for framework-like extensibility and screen size responsiveness.
