I had the pleasure of working alongside John Kavanagh on a project focusing around building static webpages for a client, as well as improving their current webpages. John was an absolute pleasure to work with, he knows how to benefit the project and is able to get his point across without being offensive, this really helped him share his vast knowledge of JavaScript, Gatsby and Contentful.
I can see John fitting into most environments as he has a great sense of humour, can read the room and has very advanced soft skills."

I had the pleasure of working with John Kavanagh during his time as a contractor on our Web Experience team at Nando’s. He made significant contributions to our technical SEO capabilities, delivering excellent structured data work across our recipes, blog content, and product pages. His implementation of JSON schema markup notably improved our search indexability and how our content appears in search results. He was also instrumental on updating the VI of the restaurant pages and completed that on his own.
Beyond his technical expertise, John brings a wealth of experience from his impressive career background and fits seamlessly into team culture. He's genuinely enjoyable to work with ‑ down to earth, approachable, and someone you can rely on to get the job done. His positive energy and collaborative nature made him a valued member of the team, and I wouldn't hesitate to work with him again. We will miss him at Web Ex."

John is never fazed by project management/requirement issues as are common in these environments, instead, he always finds a way to deliver value to both the end consumer and the business. It's not always easy to remain level‑headed and calm on high‑pressure projects but John's good nature and professionalism invariably remain infallible. It's an absolute pleasure working with him."

"
John Kavanagh is an 'above and beyond' front‑end developer. By that, a task could be assigned to John and he would complete it effectively, but more than that, if involved at the beginning of the process, he would add so much more value to the project in way of ideas, solutions, process, search optimisation, user experience and so forth."
