What I use
Private Internet Access (VPN)
Having a VPN system is important when browsing the internet, it will keep all your credit card and personal data safe and allows you to catch up on your favourite shows while abroad. You can read more on the blog post here
Sublime Text Editor
I previously used PHPStorm but now use Sublime Text when coding websites and email templates. I found it an fantastic lightweight piece of kit that has so many plugins you can add to help you along when coding
Adobe Creative Cloud
Even though it's a little pricey, I still don't think there is much elsewhere available when it comes to photo editing and creating SVG's, print and templates for email and web.
For years I was on the fence about whether to use Litmus or Email on Acid, both are brilliant systems for testing your email templates but with the latest updates, Litmus pipped it!
I have only recently been shown slack but found it really useful app to have when talking to other developers! You can easily create groups and share, images and even code! It also have useful mobile and tablet app so you can chat even when travelling
Airbnb is an fantastic app when travelling, it easily shows you properties available for rent and gives you the option to filter so can get the property right for you
Having coded so many email templates than I can count, I have been fortunate to be able to use the software that sends them out and found that AWeber was the best for easy to use and the wide range of options available
I've spent a lot of time, researching hosting as it's really important being a web developer and found that TSO Host where the best for uptime, easy to reach staff so any problems were dealt with easily!
