About Stanislas

For almost 12 years now, I have been developing native iOS and Android mobile applications as well as the backend supporting them in Rails.

Throughout this journey, I have had the opportunity to work on a wide variety of projects, ranging from applications created by passionate individuals in their field such as PUSH Artst, Team for the Planet, Edencast or Odysound, to improving white-label streaming solutions, and quality audits at the M6 group or Société Générale.

From 2019 to 2022, I had the chance to work with the studio LostMechanics and hone my skills in Ruby on Rails and Docker, by implementing a robust and resilient hosting solution for our clients, as well as a reusable multi-tenant platform for various mini-games developed for clients such as Ubisoft, MSI, and Wimbledon.

Today, I want to focus my energy on human-scale projects, projects that drive you, and enable you to achieve them smoothly and precisely. Beyond development, my role is also to guide you in designing a solid, accessible solution that is a pleasure to use for both you and your users.

So if you also prioritize quality, if you no longer want to sacrifice accessibility, and if you understand the need to take the time to do things right, in short, if you are looking for a locally sourced, organically grown developer, contact me!

Do you have a larger-scale project and also need a competent designer and a quality full-stack Ruby on Rails developer? Don't worry, I'm used to working with two trusted individuals!

Stan is very professional and pedagogical. His technical explanations are clear and accessible to the layman, even on complex subjects. We had to make several changes, improvements, and constructions on our site developed in Ruby on Rails, and everything went perfectly well. I highly recommend him!

The mission involved taking over and evolving a mobile application, and it's clear that Stanislas handled these tasks brilliantly, while respecting the initial deadline. A big thank you to Stanislas for his responsiveness, his thoughtfulness, and his ability to take initiative to best meet our expectations. :)
