Summary

As a freelance expert in product strategy and digital transformation, and an experienced Interim Product Manager for Digital Products, I bring nearly 14 years of hands-on expertise in the agile development and validation of digital products (web portals, apps) using the Lean approach.

My proactive, hands-on mindset is reflected in the design and implementation of innovative solutions, where transparency and close collaboration with all stakeholders are key to success.
