Welcome to Enzed Online!
What does a Kyrgyz glacier have to do with an IT consultancy? Not a lot, but it does highlight one of the fundamental keys of engagement in web design: to pique curiosity on landing on your site to encourage reading on, you've generally got a couple of seconds to do that before the visitor's attention span runs out and they move on to the next attention grabber. Mostly though, it's there because Kyrgyzstan has some of the best and most undeveloped hiking I've ever come across. If you have a chance, go!
This website was created using Python, Django, and Wagtail CMS. On the tech blog, I'll be sharing plenty of experiences, pitfalls, and tips for anyone who might find this beneficial.
About me: I have 23 years of experience in IT across a broad range of industries and roles, mostly as a contractor and consultant, ultimately as head of IT for a leading international tourism company in New Zealand. In between, I love to travel, hike and photograph (the three happily go together), as well as experiment with different cuisines from around the world.
These days, you'll find me in the countryside close to Wellington. If you're an employer looking to fill a position in your team that you believe I'd be a good fit for, either on a project basis or on a more permanent basis, please visit my About page or contact me directly here. I have rights to work in New Zealand, the UK, Spain and Australia, and would be happy to consider other locations as well.
Here, I'll be sharing insights from my professional experiences, studies in data science and web development, and explanations of how this site was built for anyone interested in learning.
If technology isn't your thing, check out my other major passions: travel, hiking, photography, and world cuisine. I like to combine as many of these as I can whenever I get the opportunity ...
