Hi, I'm Jon Openshaw...

...an experienced full stack web developer and former technical and strategic SEO (I still do consulting work!). I've worked at CARFAX, Pager, MikMak and Store No. 8.

I'm comfortable in React and Vue on the frontend and Node/Express on the backend. I have experience with React Native, Nest.js and Ruby/Rails.

I love analytics, A/B testing and measuring performance. Really love learning new things. Recently experimenting with Elixir and Rust.

Connect with me on LinkedIn for more info (and please introduce yourself if you do).
