Sailing, Food, Programming, Technology, and other things
I am Will Jessop, CTO of Impactive and a Ruby on Rails and Postgres upgrade and performance consultant. I run Own&Ship, an app for tracking Ruby and Rails deprecations and helping manage upgrades.
I blog sporadically about my sailing adventures over at the Silver Girl website.
