Source 2 moves its offsets every patch, so a hardcoded SDK is stale within a week of shipping. This one reads the schema out of the running process instead, which is the only version that stays correct. Published as dezlock-dump.

The 5-minute version, from meRecorded for founders sizing up a first or a founding engineer. What I build, who I've built it for, and who I'm looking to work with.

Hey, I'm Doug.

I've built products for Framer, Contra, Groupon, The Motley Fool and Sky. I'm a subject contributor on MIT's Generative AI and LLM course, and I've founded and sold three products of my own.

British software engineer and founder, twelve years in. I'll work out what to build, design it, write it, and then do the work that gets people using it. Most of what I ship now has an LLM somewhere in it, and I write nearly all of it with agents.

Some shape on the timeline: WithSeismic is the consultancy I've run since 2016, so most of the client work sits under that, and the founder entries are products I built and sold alongside it. hogsend.com is the current one.

Both are libraries I run in production, so the contributions come out of bugs and gaps I hit in real work rather than from going looking for something to fix.

Lead Product Engineer / Creator — hogsend.com

A code-first lifecycle platform: durable event-driven journeys, real-time segmentation, first-party identity and revenue attribution, all in one system.

  • I built it because I had hand-rolled the same lifecycle and attribution stack for client after client, and I wanted a version you can test like code.
  • I designed the multi-package SDK, the typed providers and a deterministic harness, so you can assert a journey in CI instead of clicking through a canvas.

  • Shipped a mobile app on both the iOS App Store and Google Play, built with Expo, alongside the web product.
