+ Oversee quality assurance and validation processes to confirm that modernized systems meet performance, reliability, and functional requirements.

People & Practice Development

+ Lead, mentor, and develop a team of modernization professionals, fostering a culture of continuous learning, accountability, and innovation.

+ Define talent and capability development priorities for the practice, identifying skill gaps and sponsoring targeted growth initiatives.

+ Communicate complex technical and program status to both technical and non-technical audiences with clarity and confidence.
