Project Manager
Meet Marianna Marszałkowska, our Project Manager, specialising in delivering large-scale Workday programmes from initial planning and global HCM implementations to complex finance and payroll integrations. Marianna is known for transforming intricate technical requirements into clear, actionable roadmaps that help organisations unlock the full value of their Workday environment.
As a Project Manager at Coreteam, Marianna acts as the vital bridge between partners and clients, ensuring Workday projects are delivered smoothly, on time, and within budget. Beyond the technical rollout, she places strong emphasis on change management, supporting teams through clear communication and effective training so new systems are not just implemented, but truly adopted.
Based between Poland and the Netherlands, Marianna enjoys gaming, baking, cooking, and exploring astrophysics in her downtime, balancing curiosity, creativity, and a love for learning, both in and out of work.
Colleagues know Marianna for her ability to always see the light at the end of the tunnel, her thoughtful questions that get to the heart of complex challenges, and a touch of dark humour that keeps even the toughest moments grounded. Dependable, supportive, and endlessly organised, she’s the kind of teammate who can feed a whole crew, build the perfect vacation Excel, and keep everyone on budget, while making sure no one feels alone along the way.
