Rob Waller

I have spent the last 13 years working in the software industry, I've written lots of different code including JavaScript, VB, C#, Bash, SQL and Python. I have spent the majority of my career writing PHP, I'm a massive fan of the community and attend many community events. I am currently a contractor and consultant specialising in PHP, Python and JavaScript. Prior to this I spent two and a half years at Breakthrough Media as Head of Technology where I managed a team of PHP developers working on WordPress and Laravel projects. Before Breakthrough I was a contractor and ran my own business. I had some success, I built an app that got my business mentioned in Mashable and on CNN, I then sold my business, and finally I nearly went bankrupt. It was a crazy, fun and depressing period. I learnt a lot though, for example, make sure you read and understand every line of a contract before you sign it. I'd advise everyone to try and run a business at some stage in their life. Overall I believe I have a great deal of insight and guidance to offer developers and aspiring technical managers. Not just based on my current role but also my previous business experience. I would love the opportunity to share my knowledge and experience with a wider audience. You can find out more about me via the following resources, you'll note I also have a degree in History which I hope shows I'm a well rounded individual.
