Bio: 

Merlin A. Rutz is head of HOOK_DEV_ALTER, a consultancy that hooks in when things get dicey. Coder, architect, agency lead and owner of a SaaS product.

For ten years he has asked code and data the same question: what do you depend on?

Current work: Drupal on persistent PHP workers, and what it takes:
- structured concurrency for PHP
- state that stays inside its request
- upstream fixes for the bugs found on the way
