Hi there 👋
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/3in 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 😉)
- gpx_ex 1, 2
- domainatrex
- geoip
- geo
You can find me on Twitter or on Mastodon.

Dever Elixir Meetup: Fantastic Hacks and Where to Find Them
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.
