Backend Banter

Today we welcome YK Sugi—engineer, educator, and the mind behind CSS Dojo—for the final episode of season two.

We talk about his journey from YouTube dev tutorials to building one of Sourcegraph’s most-used AI tools, and how the role of DevRel has changed (and in some cases, disappeared). YK also breaks down how senior engineers are actually using AI, why fundamentals still matter, and how Agent Chat was born during a company hackathon.

If you’re curious about AI devtools, the future of DevRel, or just want to hear how a former YouTuber accidentally shipped a flagship feature—this one's for you.
