We are excited to host Jason Malcolm to talk at Chicago Crystal about his experiences running Crystal in the real world.

Blitline: Our love of crystal by Jason Malcolm

I work at, an online image processing service, and for years now, we have been using Crystal in production for a number of our microservices which support Blitline. These include logging, caching, and queue platforms custom written in Crystal. In this talk, I’ll outline a bit about our custom Crystal services, and go over a central piece of this infrastructure that it all shares, our tcp_engine.
