> Senior Software Engineer

I build the APIs that background screening runs on.

Every company hires through different software, and all of it eventually has to ask the same question: does this candidate check out? I've spent eight years building the systems that answer it — five on the connections themselves, making a pile of incompatible platforms behave like one. Lately: Java and Spring Boot, Angular on the front end, and the AWS setup it all runs on.
