Design. Deliver. Nurture.

Tesrex was founded with two core fundamentals; provide exceptional customer service and to deliver the best possible solution for our clients.

In order to accomplish these goals, we think of ourselves as an extension of your team. We’ll take the time to truly dissect your business needs and utilise our vast industry experience to explore all of the available options.

The most exciting parts of consulting are education and exploration. Whether it’s walking into a completely new environment or nurturing the growth of our existing customers, the satisfaction is derived from an insatiable hunger for knowledge.

We hope our passion is readily apparent when you interact with anyone at our company and we look forward to having you meet our team!

  • Robert Walia, Founder

    I have been working in the technology industry since before even leaving High School. I’ve always had an insatiable thirst for knowledge. I ventured into the consulting side of business before taking a CTO position at a large, nationwide North American company. However, the consulting element of providing solutions that were well above expectations to client after client kept drawing me back in.

    Now my goal is simple: Assemble the best team to deliver the solutions to our clients that I would be happy with, if roles were reversed. For hobbies, I enjoy keeping up to date on all tech happenings, tracking cars, watching Formula 1 and GP bikes along with family time.

  • Leanne Mayall, Director of Operations

    I was born and raised in the UK and completed my BA and MA here before moving to the California Bay Area for seven years. Having had the opportunity to work in the Silicon Valley, I'm excited to bring the work ethic and high level of customer service I experienced there to the UK, as well as innovative new technologies.

    My background has focused on internal process audits, workflow and budget optimisation as well as recruiting and employee management. I'm thrilled to be coming on board at Tesrex as Director of Operations and look forward to working with our clients to ensure our promise of nurturing relationships is always fulfilled. I am particularly drawn to the straightforward and transparent nature of the company and believe both our internal team and clients will appreciate this.

    In my spare time I enjoy travelling, cooking and socialising with friends and family.

  • Adam Mountstephens, Account Manager

    As a keen student of technology and with a fondness for creativity I was always set to work in or around technology. I started out as a Network Engineer / Administrator based at a fast growing London based company. Eventually my natural creativity saw me move into Graphic Design and Marketing.

    I very much enjoy collaborating with others towards a common goal or solving a problem. As a result of this I’ve always found myself working in client facing roles. I understand the importance that a good working relationship brings to the table when working on large projects.

    In my spare time I enjoy listening to and playing music (guitar / piano), cooking, technology and spending time with friends.

  • Ruben Cocheno, Principal Architect

    I grew up with a voracious appetite for computing, following a Master’s Degree in Information Technology a few years later, I've now been in the Networking & Security Industry since 2004.

    My growing passion for IT lead me to be CCIE certified and gave me the thirst of doing better and achieving more. I work primarily with large, high-performance Enterprise Network Architectures, designs and systems. My experience allows me to provide many design, implementation and support solutions within many diverse network technologies becoming more agnostic driven.

    I run a personal blog (Cocheno.com), where I share my experiences and own opinions in diverse technologies among different vendors. In my spare time I enjoy spending time with family (including friends and pets), reading, watching movies, listening to music and outdoor sports.

  • Dylan James, Senior Collaboration Architect

    I regard myself as a technology evangelist and have always had a fascination with IT Systems particularly in telecommunications and networking. As such, my aim has always been to help people and companies flourish in their chosen workspace. My IT career spanning over 11 years has led me to disentangle and solve complex enterprise network issues both in the datacenter through to wide area networking, with a focus on Collaboration, Mobility and Remote Access.

    I hold a CCIE in Collaboration, MCSE and I am a key contributor on numerous Cisco Community support forums.
