I’m a full-stack engineer with 8+ years of production experience building high-scale ad-tech platforms at Expedia. I’ve spanned distributed backend systems and modern React frontends, and I focus on owning features end-to-end—from architecture decisions to delivery.

At Expedia, I designed and implemented the Snapshotter, a Flink application that reduces bidder service boot time by pre-computing and persisting state. I also built an Inventory Forecaster that predicts ad supply volume with high accuracy, segmented by country and time of year, to enable more reliable campaign planning and delivery guarantees.

I led end-to-end delivery of a scheduled email solution by coordinating across backend (Java/Kotlin, AWS SES/Lambda) and frontend (TypeScript/React) teams. On the product side, I improved core funding APIs to reduce processing latency and improved reliability for advertiser billing workflows, and I’ve driven UI development across ad-management tools by owning component architecture with React and MobX.
