I’m Tyler. I like Elixir, functional programming, distributed systems, and soft-real time systems.

I’m building a new take on website monitoring called SleepEasy. I blog about the behind-the-scenes stuff (tech choices, marketing, customer development, and more) at tylerayoung.com.

In the past, I created CBTea, a tiny, privacy-focused cognitive behavioral therapy app.

As part of my work at Felt, I maintain the geo and geo_postgis Elixir libraries.

Here are some of the open source contributions I’m most proud of:

• Enum.slide/3 in Elixir 1.13
• PR to double the performance of simplifying large geometries in simplify_ex
• genserver_architecture, the code that accompanied my ElixirConf 2021 talk
• elixir-raknet, the core of the Elixir-based massive multiplayer server I built for X-Plane
• ultimate-elixir-ci, the distillation of a lot of experience running Elixir in GitHub Actions CI
• Unbound, a Mac photo browser I took over at the start of the pandemic.

Other miscellaneous open source PRs I’ve contributed:

• Phoenix LiveView 1, 2
• Fix for a memory leak in the Bloom filter used in DuckDuckGo’s iOS app (proof that I know what a pointer is 😉)
• whois.ex
• gpx_ex 1, 2
• domainatrex
• geoip
• geo
• open-api-generator

You can find me on Twitter or on Mastodon.

An attendee described this talk as “juggling chainsaws for fun.” It’s about a bunch of very nerdy CPU performance hacks available on the BEAM (the Erlang & Elixir virtual machine). Not many of which are recommended for normal use, but many find one or two use cases across a big enough codebase.
