Her work spans modernizing technology landscapes, building digital platforms, redesigning end-to-end processes and customer journeys, and reshaping the operating models needed to sustain change.

  • developing and rolling out AI use cases for a public-sector organization, including defining the functional target picture and secure technical architecture, as well as driving organization-wide training and adoption
  • leading a large-scale omnichannel transformation, from defining business requirements and the technology-integration road map to redesigning end-to-end customer journeys and reshaping the customer-service organization
  • establishing a new digital business unit for a health insurer, defining its strategic ambition and road map, and building the organizational and governance structures required to deliver on it
  • reshaping IT organizations, including redesigning organizational structures, optimizing service portfolios and delivery models, and modernizing legacy technology to improve operational and financial performance
