Komplex projects demand a lot of teams. Focus, flexibility, and the ability to incorporate changing demands every day. Not to mention great communication within the team and with other stakeholders.
Kanban is a great tool to lead projects. Teams can work self organised and autonomous to reach the given goals, if they use kanban in the right way and tune their workflow over the course of the project.
I offer to lead your complex projects by leading the project team(s). The goal is to reach the project objectives, but also to establish teams that can use kanban as a basis for their work, along with other agile or lean tools that help their team enivronment.
