I'm the founder of WebShopApps and ShipperHQ. I am from the UK but now live in Dublin, Ohio.
We specialise in shipping extensions for Magento. My husband was an ecommerce merchant up until 2013 when we moved to the states and he was one of the first sites in the UK on Magento. WebShopApps was born out of my experience in setting up his shipping!!
I pretty much live/breathe shipping, so if you have any questions feel free to get in touch. Unfortunately I don't get much/any free time, so not interested in getting involved with side projects, etc.
WebShopApps/ShipperHQ are Gold Technology Partners with Magento.
