Recommendations

Justin is a wonderful web developer, and more importantly, a flexible one. As with lots of the best agencies, we need to continually shift and adapt with technology and the changing face of client needs. Justin has continually been a valued member of the team and his ability to shift with those requirements, be they industry, or client based, is testament to his ability and passion for producing great work.

Highly recommended.

We employed Justin's highly accomplished Drupal skills for a few initiatives during 2014 and 2015. He is highly-professional at handling issues and developing websites in tandem with our in-house design and development teams. What really stood out was his conscientiousness and eye for detail, I can strongly recommend him.

What more can I say apart from Justin is the best in the business, bar none. Having worked with a number of web developers in my time, it's the attention to detail that sets him apart from all others.
His approach is both clinical and creative. He will listen to all requests, make suggestions where relevant, and - more importantly - never shy away from a challenge when others would. From the over-coded mess that was to be our new website, Justin helped us unravel and develop an ecommerce store that was ready for launch in less than half the time we’d already accrued with our previous developer.
Put simply, to choose anyone else over Justin would be a bad business move. I cannot recommend him highly enough.

There are few better web developers or IT problem solvers than Justin, he is also a skilled creative designer. He took a failing project over and turned it into a successful one within three months. The previous developers had taken six months to create a poorly developed mess. Justin had to unravel it all and find fixes for so many things. He has good knowledge of business and will provide you with a solution that fits your needs. Once he knows where you want to go and what you want to achieve he will find you the best path forward.
