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.

Today, we bring a very special guest, one whose face you might recognise, one that appears on your homepages with a sporadic video and seemingly disappears. His name is Benjamin Burke, or simply Ben, he’s the co-creator of KRAZAM, a channel that consists of sketches that combine grotesque and absurdist humor with technological anxiety, satirizing the tech industry and the modern alienation of the corporate life in general.

In this episode, which admittedly is a bit different from the usual, we’ll focus on KRAZAM and its origins, creative process, and what future plans and ambitions the duo has. Both Ben and Shiva started in software engineering, met in college and started doing sketches just for fun, not expecting this project to explode in popularity in the way it did. Ben will also share their unique approach to content and why KRAZAM prioritizes loyal viewers over virality, comedic inspirations. Stay tuned!
