I've used the following technologies in a professional environment: HTML, CSS, SASS, JS (ES6), React, Redux, Mocha, Webpack.


Although I'm focusing on Frontend development, I can also maintain and improve an architecture using PHP, NodeJS and MySQL.


I also created a desktop app that relies on Electron JS and animated most of this website thanks to GSAP.



Being a member of the UX team at GuesttoGuest, I've been able to take part of the creation of the design system (with Storybook) and challenge designers and product owners on subjects like ergonomics and usability.


In order to create cross-device, impactful, cohesive interfaces, I use Responsive design and SVG animations as well as design frameworks (such as Material design).

Soft skills


Having worked in different types of companies, I believe that being meticulous, reliable and hard-working helped me complete the challenges I've been given. I'm always trying to satisfy my curiosity by reading about new technologies and how to improve myself.


I'm very keen on sharing with my team mates in order to help each other grow. As a team player, I always try to help my colleagues when I can and learn from them when possible. I'm compassionate and try to see the problems for their perspective. I also take part in the organisation of fun events like team buildings.
