Tech lead for the Fleet Services team, responsible for orchestrating Zipline's fleet of Platfrom 2 drones.
- Architected Zipline's "Platform 2" (P2) fleet management strategy at a business/concept level. Worked cross-functionally to define fleet scheduling primitives, drone-dock relationships, core mission structure, and other fundemental concepts.
- Organized critical projects spanning the software organization, including the first end-to-end integration effort connecting a customer order to drone takeoff software.
- Directly implemented multiple systems critical to Zipline's P2 operations: Fleet state tracking in the cloud; an integration testing platform for testing business-level scenarios across company-wide cloud services and drone hardware; tooling to deeply examine the execution status of all fleet cloud software.
- Mentored numerous software engineers across the Zipline organization.
Early and long-term member of GRAIL's engineering staff.
- Core Team Lead for the commercialization effort of GRAIL's GALLERI multi-cancer screening test: Receive a test order, verify patient details, manage the test lifecycle, produce the test report, and deliver the report to physicians and patients. Designed the high-level architecture, prototyped early versions, organized a team of 20+ engineers, implemented key platform components, reported progress to leadership.
- Directly managed a team of eight engineers, forming the core of the GALLERI commercialization effort.
- Tech lead for lab automation team. Designed and led the implementation of the lab workflow management system, which scheduled work across automated lab instruments and human operators to execute GRAIL's core assays. "An operating system for the lab"
- Transformed GRAIL's engineering interviewing practices to ensure a strong, consistent interview signal while simultaneously delivering a positive candidate experience.
- Delivered fun tech talks: "Baking at GRAIL" (What is software engineering?) for the non-engineering contingent at GRAIL; a satirical "Blockchain for GRAIL Storage Infrastructure."; a biographical "The Making of a Treaster".
Member of the Devtools/Build Infrastructure team, responsible for maintaining a continuous integration system used by all of Dropbox engineering.
Built a web-based service to help realtors manage and organize transaction documents.
Designed, implemented, deployed, documented, maintained, and supported a variety of mission-critical productivity tools and services, used by engineers across Google.
- Deleted Internets - Built a service for monitoring data on a distributed filesystem and deleting files at appropriate times using a policy specification language. Used by teams ranging from Search, Ads, GMail, Maps, and YouTube, deleting petabytes of data per day with hundreds of service instances company-wide. In 2021, was invited back to give a talk at Google to discuss how it's been such an enduring service. (Still in use last I heard, well over 1000+ instances company-wide)
