👋Hi, I'mKatia Wheeler!

I'm a Senior Developer with 10+ years of experience building awesome things.

Picture of Katia Wheeler

Nice to meet you!

I'm currently building cool things at Shopify (like the Shop app), utilizing my expertise in frontend technologies, such as React and React Native. I've worked full-stack across multiple languages over the years, so I'm comfortable jumping into pretty much anything.

I'm really passionate about mentoring developers and finding ways to make teams move faster. Lately that's looked like building an AI workflow to crush flaky tests and gamifying bug bashes with a leaderboard. I've also taught JavaScript and React at a community college and given a few talks (including one on Atomic Design).

Outside of work, I'm either spending time with my wife and kids, making music, or drinking coffee.
