Yuki Tanabe

Yuki is a senior web performance consultant based in Berlin with 13 years in the trade. She did five years at Akamai as a solutions architect for European media customers, tuning CDN configs and edge cache rules for newspapers handling 8-figure daily pageviews, then moved to Zalando as a staff engineer on the Mobile Web Performance squad. There she ran the project that cut JavaScript shipped to product detail pages by 41% without losing any tracking signals the marketing org cared about. She holds the Google Mobile Web Specialist cert (back when it existed) and contributes occasionally to the web-vitals npm package. Her writing tends to focus on perf budgets that actually survive contact with a product roadmap, image pipeline strategy beyond just slapping on AVIF, and the unglamorous work of getting RUM into a CI pipeline that PMs will read.
