My track record of developing and delivering high-quality solutions within tight time frames is a result of my strong communication skills and ability to quickly build professional relationships across all levels.

I am passionate about using Project Management principles and Agile practices for continuous improvement and driving business outcomes. My background includes roles such as Scrum Master, Quality Assurance Lead, and Senior Customer Relationship Management Consultant, giving me a broad understanding of the various aspects of technology projects. Additionally, my experience in facilitating solution compliance to security, privacy, and regulatory needs, overseeing technical debt and technology obsolescence, and advocating for the adoption of new technologies into solutions is invaluable in my current role.
