Profile: https://flows.cv/christopherbradshaw

Senior Software Engineer at Spotify with experience building large-scale advertiser-facing platforms across reporting, measurement, and campaign tooling. I’ve led high-impact initiatives including the Spotify Brand Lift (SBL) survey booking flow, Pixel & Measurement launches, micro-frontend migrations, and a GraphQL/TanStack Query reporting platform — driving measurable revenue impact, improving system reliability, and accelerating engineering velocity.

I specialize in owning complex product surfaces end-to-end, collaborating closely with backend, data, and product partners, and shipping systems that balance correctness, performance, and developer ergonomics.
