Acerca de William
I have been a Product Manager for three years, specialising in the management and delivery of digital products (mobile, web, back-end) in complex environments: multi-team projects, international projects and migrations.
I support my clients in scoping, prioritising and delivering digital products on time using a Lean approach (focus on user value, short iterations, continuous improvement), on highly complex and large-scale projects (10 million+ users for EURO 2024, migration of 1 million+ files, post-acquisition integration).
