Jon is a world class technical architect in his field and I would strongly recommend him for anything he wishes to apply himself to.

Simon Forster – Consulting Infrastructure Engineer

Jon is one of the most talented administrators I have worked with. He’s technically very strong and combined with his attention to detail, professional attitude and personal qualities, he’s somebody I’m looking forward to working with in the future should the possibility arise.

Over the years in my role as a consulting engineer working in the same company as Jon, I’ve been very fortunate to have released a lot of infrastructure into production status in collaboration with him. Jon has been able to adapt well to operating many different systems effectively, and has regularly contributed operations experience into project design and execution phases.

Specifically, in recent years, Jon has been primarily responsible for running VMware infrastructure in a demanding London-based banking environment, including additional responsibilities in some international trading locations. Jon has been instrumental in driving the use of virtualisation technology forward, in parallel gaining recognition and accreditation in the vendor marketplace as a VMware vExpert.

In order to be successful in his role, Jon had to work at a very technical level on associated topics like storage and networking, where attention to detail is paramount. One of the most rewarding aspects about working with Jon is that he is quick to learn, and immediately engages critically with the topic at hand. He questions appropriately, and demonstrates an ability to evaluate whether a specific technology will introduce additional complexity or refine a solution. This ability is vital when dealing with complex systems. Indeed, because of the transparent and thoughtful manner in which Jon works, he has taken more and more responsibility for engineering topics, freeing up valuable engineering time for his colleagues.

On a more personal note, Jon has a great attitude to work and is passionate about the job he does. He is willing to help others and will be an asset to any team. He can be relied on implicitly to step up and do what is required to ensure production service is maintained. It’s a pleasure to recommend Jon and I’m looking forward to working with him again in future should the opportunity arise.

Jon was very knowledgeable of the VMWare environment and extremely thorough with test results providing strong arguments for why we should and shouldn’t adopt certain technologies.

During the migrations Jon was always available per schedule and went over and beyond what was required of the team to get the VMWare environment on to the new technology ASAP.

Away from the above projects, Jon provided excellent support for any issues and tasks that were required as part of the day to day running of VMWare and many Windows tasks and I found him to be an excellent colleague within the team to work with. I would definitely like to work with Jon again and can only imagine that he would make any IT team that much better and stronger.
