Hi, I'm Lucas B

Senior Software Engineer

Building reliable systems and considered interfaces.

I design and build software that is reliable under load, pleasant to use, and easy to evolve.

Selected work

A few projects I'm proud of.

Sub-second analytics for an event-heavy product, ingesting 100k events per second with interactive queries under 200ms.

A reliable task orchestration platform with retries, scheduling, and observability, running tens of millions of tasks per day.

A GitHub App that gives PR authors fast, focused, line-level reviews from a fine-tuned LLM, integrated with existing CI tooling.

Notes on engineering and craft.

A step-by-step guide to migrating a Hugo site from Tailwind CSS v3 to v4 with the new CSS-first configuration.

Speed up the pacman package manager with parallel downloads, nearest mirrorlists, and faster AUR compilation.
