• Support backend development to accelerate workflows, and mentor team members in doing the same.
• Develop robust experimentation frameworks and conduct analyses to support revenue growth and optimization of advertising product.
• Communicate insights clearly, challenge outdated practices, and lead pragmatic improvements.
