The partner
of local projects.
PROJETIZ works with homeowners and professionals across the Ain, the Pays de Gex and the Geneva basin — from the building site to online visibility.
Two trades, one thread
PROJETIZ started in construction brokerage: connecting homeowners with qualified tradespeople, and running their projects end to end. Over time one thing became obvious — those tradespeople, serious and skilled, were often invisible online.
Digital communication grew out of that: bespoke, hand-coded websites that genuinely belong to the people who use them. Two activities, one mission — helping the local economy get its projects built, and get known.
The founder
Who is behind PROJETIZ
My first profession was people and law. I spent several years in property transactions — buildings and business assets, first in agency then in the notarial world — where I learned the rigour of contracts, an eye for detail and the craft of guiding decisions that commit people. I have also managed co-ownership properties and served in the leadership of business-services companies, before founding my own. Always the same thread: understand a need, and answer it properly.
Alongside that, a long-standing passion for information technology. Since the early 2000s I have been coding web projects for people around me — often simply to help — while following how the profession evolved. That practice became a real direction during my nearly seven years living in Geneva, in a demanding international environment.
I trained seriously: the "piscine" at École 42 in Lausanne, close to 400 hours of C in a single month, then a professional programme at Nomades Advanced Technologies in Geneva — frontend with frameworks such as React, then backend in Python, enough to design full-stack. I also worked alongside web3 and decentralised finance, a world where security is never optional. Trained to IPMA standards and used to agile methods, I work lean: straight to the essential, no fat, no needless dependencies. Self-taught at heart, I have never stopped learning.
Today I follow data science, the development of artificial intelligence and the question of digital sovereignty closely. That double culture — law and code, commerce and engineering — is what makes the difference. It led me to a clear choice for PROJETIZ:the security and sovereignty of the projects I take on. That is not a marketing line, it is the defining issue of the coming decade. Your data, your website, your image: all of it should belong to you, and last.

Our area
Rooted in the Ain, the Pays de Gex and the Geneva basin
PROJETIZ works in Valserhône, Gex, Ferney-Voltaire, Divonne-les-Bains, Saint-Genis-Pouilly, Annecy and the surrounding area. That local footing is not a detail: it means we understand your customers, your catchment area and the realities on the ground — so the sites and the projects are built for the people who actually live and work here, on both sides of the French-Swiss border.
