Welcome to Large Code-Run Collider (LCRC), my lab notebook for learning by building.

I publish small, testable artifacts around software engineering: backend, reliability, data, boundaries, and failure modes.

Each Fill is one focused experiment: a tiny repo, a short write-up, and (when useful) a few notes about pitfalls and invariants.

If the collider doesn’t create a black hole, but instead helps me understand one concrete thing better, the experiment is still a success.

Runs

Series of Fills.

Fills

One concept, one artifact.
