• Founding engineer for the Optopod (Optimization team) - a team designed to iterate quickly, experiment frequently, and ideate on features that can move metrics. Specifically focusing on ways to engage international.
• Ran CMBs 2021 Summer Internship program. Hired 3 engineers (2 iOS, 1 Android) with a team of 10 engineers. Formulated intern projects, led their induction, assigned them partners, planned final presentations.
• Pitched and managed "Store V2": a multi-cycle project which re-architects the backend store app. Allows CX agents to audit the entire transaction history of the user, grant individual perks (in-app items), and view.
• Often take on bug fixes which would impede an experiment before it's run. For instance, resolved a long-standing (6+ month) bug which affected ~5,000 users per day in their ability to perform actions on their bagels in.

• Worked as part of the Backend Tools team. Here we created user-facing features, addressed QOL improvements + bugs, and created developer tools. Notable projects:
• Drove implementation of bringing trial subscriptions natively onto the app. No longer relying on external services to track subscriptions and giving the team more granular control in altering subscription offerings.
• Technical lead for implementation of the feature "Karma Beans": awards users in-app currency for positive interactions. Encompasses rewards that replenish daily and those which are one-off. Added caching layer to.

• Improved efficiency by scheduling periodic recurring tasks previously done manually daily: automating the daily task of aggregating + analyzing stock trends. Used RabbitMQ and Celery for the producer/consumer setup.
• Spearheaded the effort to automate unit testing as a standard codebase practice. Implemented extensive automated testing suite using pytest.
