/ Who I am
I am M. Yacine, also known as myby lelouch, a Digital Systems Designer. I design and build the digital systems businesses run on: websites, custom software and SaaS, automation, AI agents and assistants, data and search visibility.
My job is to connect what is usually split between several providers. A website here, a database there, a spreadsheet to tie it all together: I replace that patchwork with one system, designed, built and measured by one single point of contact, who is developer, data engineer, strategist and writer at once.
Every project starts from a precise problem and ends with a measured number, before and after. I work remotely with businesses in France, Belgium, Switzerland, the rest of Europe and beyond, in English and French. The code, the access and the data always remain in your name.
