Jon has been an integral member of the team and has proven himself time and again to be indispensable. His professional approach and his work ethic are exemplary. Like most of the management team I have come to rely on his expertise and knowledge on a daily basis, and Jon’s desk is usually the first place to go when there is a problem that needs fixing! His ability to provide a technical solution to a business problem without losing sight of the business requirements sets him apart from many of his peers. I would choose to have Jon on my team for any and all future projects where possible.

I have had the pleasure of working with Jon now on two occasions. Jon is a very well respected technical architect who can apply his in depth technical knowledge to minor technical issues right through to detailed technical design. Whilst at the top of his profession technically, Jon has the ability to step out from technology and understand the MI requirements of senior stakeholders. Jon is a world class technical architect in his field and I would strongly recommend him for anything he wishes to apply himself to.

Jon is one of the hardest working individuals I have met. He has a fantastic depth of technical knowledge, giving him an enviable ability to troubleshoot and resolve issues. He does this with a thoroughness and attention to detail that has earned him the respect of many people in the company.

Jon recently has been primarily responsible for VMware in London and has been instrumental in driving this virtualization technology forward in Commerzbank. He has a great attitude to work and is passionate about the job he does.

Jon is always willing to help others and would be an asset to any team. He can be relied on implicitly in the tough times to always step up and give 110%. I don’t hesitate in recommending him and hope we get the chance to work together again.

I worked with Jon during an ambitious storage tech refresh project with very aggressive timescales, and found him to be a consummate professional. Not only does Jon possess an unparalleled depth of technical knowledge in his own specialist area, he also has an outstanding working knowledge of the breadth of the IT infrastructure environment as well as an incredible ability to understand new technologies in a very short space of time.

Jon is also one of the most amiable and easy to-get-on with individuals I have had the pleasure of working with, and would be an exceptional asset to any organization.

Simon Forster – Consulting Infrastructure Engineer
August 30, 2014, Simon worked with Jon at Commerzbank

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 is one of the rare professionals combining excellent technical knowledge with highly developed social competence. He is able to quickly understand new topics and stays focused on the targets to be achieved. Having discussions with Jon is a pleasure as he is able to listen and to explain his point of view in a logical manner. Jon’s mind is free for different opinions and suggestions he makes often broaden the partners view on topics. If you need somebody with his technical expertise you can totally rely on, he definitely is one of the best colleagues I’ve ever worked with in more than 16 years now.

I have worked on several projects with Jon. Some of these include:

VMWare migration: HDS to EMC VMAX.
VMWare migration: HDS to NetApp Metrocluster.
Testing VMWare on Violin flash storage
Testing VMWare on EMC XtremIO storage

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.
