Guillaume Hammadi

Senior Software Developer

Originally a mechanical engineer, Guillaume quickly figured out that computers were at least as fun as giant telescopes. Guillaume has sixteen years of experience in software engineering around the world. His tenacity when chasing elusive bugs is only matched by how clearly he can explain the ins and outs of a system to non-technical stakeholders.
He is an avid traveler and digital nomadism is more than a label to him. He’s delivered successful projects from America, Oceania and Europe with teams all over the time zones. When Guillaume is not typing away on a clicky mechanical keyboard, he can be found on a local mountain or in a remote part of the world. Usually on a mountain bike, with a kite attached to his waist or a snowboard under his feet.

Our team has decades of experience in green building innovation, software development, and business development.

With executive and management level experience in policy-making, real estate development, property management, architecture, energy modelling, product management, and business management, we have a holistic understanding of the building sector and the leverage points to create positive change.
