software engineer / backend + distributed systems

Ben Radosevich

Product-focused backend engineer with 13+ years of experience designing, shipping, and operating production software systems.

I build the backend systems that make products work: real-time collaboration, full-text search, and the coordination layers that users might not see but always feel.
