At Channable, we have had a great experience introducing Haskell for our infrastructure projects. We have written a few blog posts about this which you can find on our tech blog[1].

- Jobmachine, an advanced job-scheduling system with dynamic dependency resolution[2]

- Vaultenv, a small open-source tool to get secrets from Hashicorp vault[3][4]

- alfred-margaret, a blazingly-fast Aho-Corasick implementation written in Haskell[5][6]

- Sharkmachine, our in-house replacement for Apache Spark[7]
