EXPERIENCE

Staff Software Engineer and Tech Lead | Asana | San Francisco, CA

JULY 2023 - MARCH 2024

As the Tech Lead of the Core Performance team, I rebuilt the team from a full quarter hiatus and set the team back up to speed. I established team processes, built the next year's roadmap and capacity planning, and led the team to ship a few projects in Q4.
Delivered a few projects and initiatives myself such as authoring a new version of the Re-render performance tests and advocating for its adoption, and a new version of the initial Asana loading indicator, which drove engagement under perceived performance improvements towards PLG under the pillar's ARR goal.
Led a cross-team customer escalation for a specific high-profile organization experiencing high user lag, where I primarily contributed with fixes that addressed several render performance issues, significantly enhancing user scrolling and pagination speeds on Portfolios. This work reduced Portfolio Grid's P95 Pagination Wait Time from 7.2s -> 3.2s for all domains, and Portfolio Page's P75 Search Field Opened Time from 1.2s -> 0.1s for this specific organization's domain.
