(External) Evan Czaplicki: Making Web Apps can be Fun!

Dear members of HaskellerZ

I am pleased to invite you to the following guest lecture from the creator of the Elm programming language, Evan Czaplicki. Please note that it is at the OST campus in Rapperswil.

Title:
Making Web Apps can be Fun!
How to use Functional Languages at Work.

Speaker: Evan Czaplicki

Date & Time: 03.06.2026 17h15-19h00
Place: OST Campus at Rapperswil | Lecture Hall 5.002

Abstract:
Typed functional languages have had success in some surprising places. From high frequency trading at Jane Street, teaching physics and engineering at Brilliant, and plenty of businesses in between. We will go through some case studies to build an intuition for why a functional language is likely (or unlikely) to succeed in a given business scenario. From there we will dive into Elm (https://elm-lang.org), a simple functional language that runs in browsers. If we have time, we will build a little website together. You should come away from this talk with (1) the core knowledge needed to build your own functional front-end and (2) an intuition for when it is a good business idea to do so. You do not need to know functional programming to enjoy this talk.

Speaker Bio: Evan is the author of the Elm (https://elm-lang.org <https://elm-lang.org/>) and Acadia (https://acadia.engineering <https://acadia.engineering/>) programming languages. He has been developing compilers and servers in Haskell for nearly 15 years, and has significant expertise in using low-level techniques to get the best possible performance out of Haskell programs.

I look forward to seeing you there!

Best regards,
Farhad Mehta
