About Me

I'm a Senior Full-Stack Engineer with over a decade of building revenue-critical systems in Ad Tech, Digital Media and Observability. At Datadog, I work on Flex Logs—a multi-tenant, multi-datacenter log storage that keeps petabyte-scale data queryable on demand.

Before that I spent ten years at Yandex, where I owned the video advertising player behind all Yandex services and authored the video creative standard still used company-wide, then built a new international advertising network from scratch—defining its architecture and growing the team that delivered it.
