Enabled ~2% increase of completed trips in several markets by architecting, implementing, and iterating on online and offline features related to the Coordinated Structural Pricing (CSP) service written in Go. This service adjusts rider and driver upfront fares in a decoupled fashion based on various Marketplace features and business constraints.Reduced redundant development across teams by designing and implementing performant caching and locking modules used heavily across Rider Incentives services and the CSP service.Improved monitoring, reliability, and developer experience by consolidating all on-call alerts into a config-driven repository. By driving an effort to proactively templatize and standardize these alerts, I reduced time to detection and mitigation for several outages and encouraged peers to fix issues in previously-unmonitored flows.Mentored interns and junior engineers alike by sharing and archiving extensive written and video-recorded documentation and by giving extensive system architecture and code reviews.

Implemented and maintained Upfront Pricing for rides by standing up microservices in NodeJS and Go and integrating them into the trip flow. This work enabled millions of Upfront Pricing rides trips.Facilitated the implementation, integration, rollout, training, and handoff to a dedicated team of the Rider Structural Pricing lever. This pricing lever intelligently applies upfront fare price adjustments to optimize for various criteria.Rolled out and iterated on walking pick-up and drop-off selection by implementing a real-time Elasticsearch-backed microservice and integrating it with the rides dispatching flow.

Employed threat modeling and penetration test techniques to conduct a security review of a monolithic Ruby on Rails application.Detected and mitigated various security vulnerabilities.Retooled and refreshed several genre-specific monthly email newsletter campaigns with hundreds of thousands of subscribers. Established teamwide practice of vetting emails pre-deployment using Litmus.

Evaluated SoCs on prototype boards by designing and running an automated Flash and Webkit benchmarking suite. Ported software to Android by writing shell scripts that utilized Adobe AIR development tools and configured various software settings.

Cultivated a new student community by founding oSTEM, a professional networking LGBT student group at UC Berkeley. Promoted oSTEM events by managing its internal and external mailing lists, by designing print ads in Adobe Photoshop and Illustrator, and by organizing tech info-sessions with recruiters. Redesigned UC Berkeley oSTEM chapter's website (in-progress).
