Sienna is a developer from Vancouver, British Columbia with a passion for creating accessible, beautiful, dynamic products and websites that spark change and empower users, for clients including the Commonwealth of Massachusetts, Warren for President, Warren Democrats, and Wu for Boston. She also holds a B.Sc. in Environmental Science (and M.Sc in Geography) from McGill University in Montreal and is deeply concerned about sustainability — particularly, how every website that’s built contributes to the internet’s total energy consumption (which accounts for more than 2% of global emissions) and what steps designers, developers, and customers of websites and cloud provider services can take to address that.
