Hi, I'm Jon Openshaw...

...an experienced full stack web developer. I still do some strategic SEO consulting on the side. I've worked at CARFAX, Pager, MikMak, Walmart Global Tech/Store No. 8 (RIP) and Uptime.com.

Comfortable in React, Vue (frontend) and Node/Express, Python/Django (backend). Mongo and PostgreSQL. Experience with React Native, Nest.js and Ruby/Rails.

I love analytics, A/B testing and measuring performance. Recently experimenting with Elixir & Phoenix Liveview and Rust.

I'm currently looking for a position as a frontend-leaning fullstack developer, so please connect with me on LinkedIn ! I'd love to meet you.
