Ask Daniel Brain

ChatGPT plugin

Research Daniel Brain's work

View in ChatGPT directory

Research Daniel Brain's engineering work with answers cited from his own sources: his resume, 20 posts, 7 conference talks, 2 patents, press coverage, Hacker News discussions and 23 open-source READMEs. Useful when you are hiring, investing, interviewing or writing about him, or learning from his work on cross-domain JavaScript, payments and agent checkout.

Ask a question and ChatGPT answers from those sources and links each one. Open the library to search and read everything, including the original pages, and watch his talks with a transcript that follows the video. Prepare a one-page briefing for a recruiter, engineer, investor or journalist. Read his latest updates, or ask to be notified when he posts a new one. Send him a message; only the message is required, and he can reply if you add your email.

Daniel is co-founder and CTO of OneText and was Principal Staff Engineer on PayPal Checkout, where he created the zoid and post-robot open-source libraries. The plugin needs no account and is read-only apart from sending him a message, which ChatGPT asks your permission for first.
