Haskell In Production: CentralApp


Tell us about your company, your team and your own role there.

  • Backend programming and architecture
  • Ops
Ashesh Ambasta
  • Haskell and some Scala (legacy)
  • JS on the frontend (maintained by a separate team)
  • MySQL + PostgreSQL
  • Redis
  • AWS
  • S3
  • Docker + Stack for tooling (we’d like to move to Nix completely)
  • Emacs + Dante for editing
  • Tooling
  • Editor integration: the tools available are buggy or need a lot of manual configuration.
  • Documentation
  • Haskell is amazing for large systems.
  • Haskell is very much ready for production and being applied in the industry.
  • We’re a web company, we’re not doing anything super-academic with Haskell, as per its reputation goes. And Haskell is helping us run a profitable business with a backend team as small as 2 people working on what could almost be a 200k LOC codebase.
  • Haskell’s tooling, given your ability to invest in it, needs some work. But it isn’t as bad as the buzz suggests. The existence of things like Nix etc. helps this further.
