I build resilient distributed data, streaming, and customer-facing software for large-scale platforms.

At Snowflake, I design distributed data services and ingestion pipelines for secure analytics and retail-style reporting, improving deployment success by 20% and reducing mean time to recovery by 15%.

I've also built video APIs and dashboards at Mux, large-scale commerce experiences at Facebook, retail platforms at Target, and medical imaging software at Vital Images. I work end-to-end across backend services, data platforms, APIs, React applications, cloud infrastructure, testing, and observability.
