Become a sponsor to Daniel Spiewak

I'm the creator and current BDFL of the Cats Effect project, long-time speaker, and member of the Typelevel Steering Committee. I primarily work to facilitate and encourage the growth of strongly typed, purely-functional, asynchronous, industrial software development within Scala. This mission has a lot of multi-faceted manifestations, but almost every task I undertake in the public domain traces back to it, including my involvement with Typelevel, my involvement in the Scala language, and the existence of Cats Effect in the first place.

I work for the furtherance of these goals specifically because I (currently!) believe they represent the most effective way to build software sustainably and scalably, now and into the future. I find it very rewarding to help influence and empower the industry to grow these techniques and employ them writ large.

I also sometimes fall down very researchy rabbit holes, as you can see if you peruse my profile at sufficient depth. I still hold a special place in my heart for parser theory and algorithms, and I'm certainly not immune to a good nerd snipe when trying to get the Scala language to learn new tricks.

If you would like to sponsor my work, you can do so here! My employer is very supportive of my work in the open source ecosystem, and so I certainly do not need financial assistance in order to make this work sustainable (though I could use a time turner if you have one), but I'm more than happy to buy a pizza and dedicate to you. 🙂 As a practical matter, if this sponsorship fund grows sufficiently, it could make it possible for me to speak at more conferences and meetups around the world, with the goal of finding, inspiring, and mentoring a broader and more diverse set of people who could come to shape the future of our industry.

This would cover my coffee budget for the month! Or maybe it just allows me to drink twice as much…
