What Others Say
Marc is an incredible visionary who constantly surprises me with his ability to create awesome new things, educate and grow those around him, and bring more to his projects than anyone expects.
Marc's understanding of client-side development runs deep and he was more than happy to share his knowledge with the broader team — we all learned a lot from him.
He's one of the most dedicated, skilled, and inspiring developers I've ever worked with.
