Web developer Web integrator UX designer UI designer Amateur writter


Currently based in Paris, I'm passionate about CSS animations, UX , and design. Designing allows me to explore and express my creativity and inner world, and if it's through my work, that's a great fulfillment. I've worked as a web developer and integrator for 12 years.

Lover of the planet, nature, animals, and people; I add passion and respect to everything I do. I spend most of my spare time reading and writing, from personal reflections to UX case studies or piano music.

I believe what brings expertise and mastery is not your skills but your hard work and passion.

A little bit more background

I started my professional career in 2007 in London as a Ruby on Rails developer. I explored areas like frontend, backend, JS, agile (SCRUM), hosting, or web design.

I lean towards the visual and artistic. I've been focusing on responsive web design, HTML5, CSS3, mobile-first development, css3 web animations, user interactions, and cross-browser compatibility for some years.

I love looking from the user's eyes, deepening, empathizing with them, and challenging myself to develop creative solutions. Indeed that's why I fell in love with Design Thinking, which seeks to understand the user, challenges all assumptions, and aims to find answers that seemed invisible at first glance.

I manage an Ubuntu server at home, which I use as a learning playground, and host personal projects.

Last but not least, I'm available for hire on freelance projects.

Project 1: Mes Amis ["my friends"] Mobile App, UX and Design oriented to kids.

Save animals while learning a language!

The project went from a blank paper to the high fidelity design prototype of a mobile app for kids. The goal of the app is to help children to learn a new language while having fun. It must resemble a summer camp experience, but it needed to happen online and bring both learning and fun.

How to translate all those personal interactions and experiences from a summer camp into a mobile app?

Personal Writing

Writing is the fuel for my happiness and life's awareness, and it also nourishes my creativity. I write about my own experiences, those around me, and anything I have seen or heard that led me to reflection.
For more stories, I host all of them under my Medium profile, where I write regularly.
