For over 20 years, I have been helping
many of the world’s largest organizations to
release the value of their data, enabling
business leaders to make strategic
executive decisions. I have a natural ability
to use divers and complex data sets to
solve real-world business issues. I have
built award-winning teams of experts that
tackle complex data problems using the
latest and greatest in data services.
I manage teams of talented data and
strategy experts as they engage with our
stakeholders in every stage of their data
journey. From data strategists who
conceptualize the flow and use of data, to
data engineers who build diverse platform
solutions to data scientists who perform
robust analytics and extract insights.
My in-depth expertise with platform
agnostic data strategy and business
intelligence design & development coupled
with my business and program
management acumen have consistently
allowed me to deliver industry-leading
solutions. Beyond these core expertise, I
enjoy looking for creative solutions to push
the boundaries of what’s possible.
