Designed and implemented an innovative data structure for managing product attributes and their relationships in an expressive and extendable manner. This initiative involved interdepartmental collaboration and a carefully planned migration from a legacy system with extensive dependencies. While the project involved some collaborative aspects, such as code reviews, the vast majority of the design, implementation, and migration planning was personally undertaken. The new structure has streamlined operations for our internal listing team and enabled a variety of high-value customer-facing features, all executed without causing any downtime.

Worked on the high traffic B2C and B2B2C stock/crypto trading APIs written in Go. Integrated a new payment rail with a teammate to support international users. My focus was on the integration side, I designed and implemented an event-driven solution for processing the complex pipelines of international transfers.Significantly decreased CI runtimes by carefully orchestrating the use of external compute resources.Implemented a code coverage reporting tool for our CI pipeline.
