- Co-authored the Devin blog post 'How Devin rebuilt its renderer' (Aug 25, 2026) with Jorge Zreik, covering virtualized rendering for sessions with hundreds of thousands of events; said on X: "@ZreikJorge and I used Devin to rebuild it's own chat renderer over the last couple of weeks we wrote about why chat rendering is a hard problem, and what we learned about collaborating with agents to build great frontends"Aug 25, 2026How Devin rebuilt its renderer, by Darragh Burke and Jorge Zreik (Devin blog).
- Joined Cognition in June 2026 as Member of Technical Staff (New York) to build Devin; announced on X: "Joined @cognition last month to build Devin! Cloud agents are a huge change to the way software gets built. They're incredibly powerful already, but they need to be simpler to use and more fun to work with. We're making it so :) If you're a Devin user, I'd love your feedback!"Jul 20, 2026Joined @cognition last month to build Devin! Cloud agents are a huge change to the way software gets built.

- X bio frames his Cognition remit as "building agent interfaces @cognition".Nov 2026
- Promoted Devin stacked PRs: "megalithic PRs are hard to review and difficult to revert if something goes wrong. With agents writing thousands of lines of code in minutes, PRs can easily grow out of hand. stacked PRs fix this completely. They're the biggest thing I was missing in Devin; now they just work!"Jul 30, 2026megalithic PRs are hard to review and difficult to revert if something goes wrong. With agents writing thousands of lines of code in minutes, PRs can easily grow out of hand. stacked PRs fix this completely. They’re the biggest thing I was missing in Devin; now they just work! @DevinAI will now automatically stack your changes in an intelligent way, or you can prompt it to organize them however you like

How Devin rebuilt its renderer, by Darragh Burke and Jorge Zreik (Devin blog).
so much thought went into getting all the little details right in the new version of our desktop app if you typically use Devin on the web, definitely give Desktop a try! I think you'll enjoy it your cloud sessions and preferences carry over, so you can jump in & keep building
We're spending all our time chatting with agents and managing our sessions in a sidebar. We need these interfaces to get out of our way so we can get things done. So we rebuilt the chat and sidebar in the @DevinAI app to be faster, cleaner and more functional
@ZreikJorge and I used Devin to rebuild it's own chat renderer over the last couple of weeks we wrote about why chat rendering is a hard problem, and what we learned about collaborating with agents to build great frontends

correct observation, and also: how incredible to living in a time where this is true! software engineering has been flipped on it's head in the last year
