Lucas supported us in the implementation of server-side tracking with Addingwell as part of our migration to a Shopify+ site. The project management was smooth and transparent, which allowed us to meet fairly tight deadlines. Lucas fully understood the specifics of this migration compared to our existing setup and brought his expertise to create the most efficient setup possible. The communication was very smooth, and the project went exceptionally well. I wouldn’t hesitate to reach out to Lucas for a future tracking project, and I highly recommend him to my e-commerce colleagues who are considering a transition to server-side tracking.

We worked with Lucas for the setup of GTM server-side and Meta CAPI on our two e-commerce websites. Fast, meticulous, and an expert in his field, we were very satisfied with the execution of the task as well as the clarity of our various exchanges with him on the subject. We will not hesitate to call on Lucas again in the future if we have additional tracking needs.

I had the pleasure of collaborating with Lucas Rollin on a complex project for the Lafreto group, which involved managing the tracking of five websites, including Glisshop. Lucas handled the implementation of server-side tracking via GTM for Google Analytics 4, the migration of third-party services, as well as overcoming the limitations of Safari ITP.

Throughout the project, Lucas demonstrated strong technical expertise, exceptional attention to detail, and an impressive adaptability in addressing technical and structural challenges. His structured and proactive approach ensured the mission's successful completion. The client felt well-supported, and I had complete confidence in his role.
