The brief

A social network built for one of the world's largest creative organizations

Publicis Groupe set out to connect its global workforce with Marcel — an internal, AI-powered platform that helps people discover the right colleagues, spin up the right meetings, and keep work moving across a company of 80,000+. Think of it as a professional network tuned for a single enterprise: profiles, matching, messaging, scheduling and deliverable tracking, all in one place.

The mobile experience needed to feel as polished and trustworthy as any consumer social app, while carrying the weight of enterprise data and AI-driven recommendations.

My role

Shipping the first release

As a badged Microsoft contractor working on the Microsoft campus, I helped build the initial release of Marcel — partnering with Publicis.Sapient to bring the first version of the cross-platform app to life on Xamarin.Forms.

What Marcel does

Three ways it brings people together

AI sits underneath all of it — quietly matching the right people, moments and work.

🤝

Find collaborators

AI matching surfaces the right colleagues and expertise across the entire organization, wherever they sit.

📅

Schedule meetings

Turn a match into a conversation — coordinate and book the right meetings without the back-and-forth.

Track deliverables

Keep work visible and moving, so teams always know what's next and nothing slips through the cracks.
