As part of the Rainmaker team, I manage and develop the company's core ad service.

My main product so far was developing a new revenue stream (Tubi Timeout), that was launched in September 2023 and earned $500k revenue in 2023.

Other responsibilities include being oncall and onduty for the services, participation in rearchitecting the system to improve efficiency and robustness and establishing team standards for coding and collaboration.

Worked on the consumer trading and core functionalities of the Gemini crypto exchange:

Improved the Google Assistant Infrastructure by designing and executing how to separate feature code from framework code in on of the Assistant subsystems. Collaborated with several Assistant teams during the process.

Supported project teams to enhance their search capabilities by using the Personal Search Infrastructure project tools.
