Previously, she worked as a Category Manager, Supplier Risk Analyst, and Procurement Systems Analyst, where she developed category/portfolio strategies, managed costs and budgets, redesigned contract architectures, introduced third-party risk methodologies, and improved procurement systems (e.g., SAP).

Tamara's project management (and business analysis) experience spans regulatory and compliance initiatives, post-merger integrations, end-to-end process transformations, and organizational changes across both traditional and Agile environments.

She joined PMI to deepen her understanding of project management best practices, learn from experienced professionals, and connect with a community that values continuous improvement. Tamara is also currently preparing for the PMP exam, which she expects to complete by the end of this year.

Outside of work, Tamara enjoys running, hiking, pilates, horse riding, traveling, and visiting art exhibitions.
