About me

I’m Louis Jackman, a technology architect in London. See my CV, my LinkedIn, my talks, my articles, and my projects and open-source contributions. Find out how to contact me.

Aside from the usual technology architecture, engineering management, and InfoSec efforts, I have personal interest in AI agent- and customer-authored code-sandboxing, LangSec, capability-based-security, declarative computing, concurrency, functional programming, compile-time metaprogramming, and programming language theory (PLT).

I’ve personally created technological solutions for companies’ messy, real-world production problems in server-side Java and Go, front-end TypeScript/JavaScript, Python for light scripting, and Rust when lower-level control was needed - all atop server-side Linux, Kubernetes, AWS, and various serverless technologies like Lambda and edge workers in CDNs.

In recent years, I have been increasingly assisted by Claude Code and OpenAI Codex at work, and have experimented with local, open-weight models like Qwen and GPT-OSS inside OpenCode.

Some other technologies also show up in personal projects and open-source contributions: client-side Linux, C, Odin, Nix, embedded Scheme variants, and Emacs Lisp.
