The world's most vibrant Haskell conference is back — in-person and online.

Connect with hundreds of like-minded Haskell enthusiasts as we explore what's new and what's next in Haskell.

Join us in London, where you'll meet fellow Haskellers face-to-face, discuss new technologies, and learn new skills through practical, coding-based sessions.

Or, if you can't make it to London, join the conference remotely via our virtual conference platform where you'll find the global Haskell community.

Back for a second great year, our popular Novice Track day will offer a bonus day of beginner-friendly talks exclusively for online attendees.

This Year's Speakers Include

Over 3 days, you'll hear the latest from Haskell thought leaders, experts and developers from around the globe.

Novice Track Day

7 December 2022

If you've heard of Haskell, but aren't sure where to begin, join us online 7 December for a day of free talks exploring the fundamentals of functional programming, the basics of Haskell, and answers to why teams use this increasingly popular language!

Whether you're new to Haskell yourself, or know someone who is — the Haskell eXchange Novice Track is the perfect place to start with one of the world's most exciting programming languages.

Who should attend?
At Skills Matter, we are strong believers in the power of Functional Programming and Haskell in particular. We truly believe that a wider adoption of these tools can not only change the software industry, but also the world.

But we also know that it can be daunting — that there's a lot to learn, and sometimes when you try to learn these things online you can get lost in the noise of people pitting one programming language against another.

Through a series of beginner-friendly, progressive talks, the Haskell eXchange: Novice Track aims to clear up a few myths, and give you the basic information so you can make an informed choice of whether Haskell is right for your use case.

If you've ever been curious about Haskell or functional programming, why not check out this free day of sessions?

What it's all about?

Haskell is an advanced, purely functional programming language.
What began as a research language has evolved into a unique, cutting edge language that is used in industries as diverse as Aerospace, Automotive, Healthcare, Finance, Education, Retail, Logistics, SaaS, Online Retail, TV and Music.

Haskell eXchange is a community-focused conference for Haskell enthusiasts. At Haskell eXchange all of the content is selected by developers for developers.

Past keynotes have included Simon Peyton Jones, Gabriele Keller, Niki Vazou, Stephanie Weirich, Sukant Hajra, Simon Marlow, and Gabriella Gonzalez


Program Committee

All of the talks at the Haskell eXchange are selected by our volunteer Program Committee which evaluates and selects which speakers and topics will be included in the conference program. This committee includes developers, practitioners and enthusiasts of all levels.

This year's Program Committee includes:
Haskell Consultant,
