Posted on (0 Comments)

Have you ever received a marketing email that you were excited to open, but once you clicked through to read the content it just fell flat? The copy didn’t register or the images felt out of place? I know I have. When I find an intriguing site and opt-in to receive their email newsletters, I expect the email experience to be similar to their site and when it doesn’t, it’s disappointing!

Conference/Event Speaking as a Developer

Posted on (0 Comments)

An Introduction to the Elixir Programming Language (And Why I Love It)   I wrote an article a few months ago introducing you to Golang, and why I loved it so much. While I do indeed still love it, lately I’ve been playing around with a new language; Elixir. I bought the book Programming Elixir and have been following it through. I’ve already come to love Elixir and hope to show you why in this article. Whilst I worked for Couchbase a couple of years back, I took a great interest in Erlang, and distributed systems. To me, Erlang is
