Get in touchWe let our work speak for itself. Here's what colleagues and clients have said about working with us.
Mark is an absolute star — great technically, able to provide thought out solutions, but also a pragmatist, able to adapt solutions to meet organisation requirements. He works great inside a team but is equally adept working on isolated tasks. We leveraged Mark's vast knowledge of Azure within our organisation to great effect. I would 100% recommend Mark and would jump at the chance to work with him again.
Mark has been a pleasure to work with. His technical knowledge in the .NET stack is both broad and deep, and his knowledge around OAuth, security and authentication in general was instrumental in resolving a number of problems. Mark's attitude and approach to the work has been fantastic — he doesn't just attack the task given but thinks outside the problem and suggests alternative, better solutions.
Mark is a pleasure to work with. Not only does he have a high level of skill with C# and a wide variety of .NET technologies, but he also brings an infectious positivity and injects energy into every project. He has a fantastic ability to work to a given specification, but also tries to see the wider picture and always offers options which will improve not only the current project but also the more general development efforts across all teams.
Was a pleasure to work with Mark over a 6 month period. Helped support our development team on a greenfield IoT project in AWS. Always delivered a high standard of work, on time and was easy to communicate with. All work was done remotely, which didn't pose any issues. Would highly recommend Mark and look forward to working with him further in the future.
I've worked with Mark a few times on a performance improvement project using Azure Functions and Microservice architecture. Mark is extremely talented, knowledgeable and very professional. He has extensive technical knowledge and is highly committed towards his work. Mark maintains calm under pressure, is very approachable and always willing to help team members with technical issues. He has an eye for detail and always strives for the best solution rather than a quick fix.
I have worked with Mark for 12 months on multiple high pressure and fast paced Agile projects. Mark is one of the best developers there is — his experience, attitude and knowledge is of the highest standard I have worked with in my career. Mark's ability to work with Product Owners and Business Analysts to ensure he codes to meet business requirements is outstanding. Any team looking to recruit Mark are lucky to have him.
Mark is a strong .NET contractor who can be trusted to deliver quality solutions to complex business requirements. Mark also has a varied technical skill set meaning he can make a big contribution to any size team, working both well on his own and as part of a team. I would have no hesitation in recommending Mark.
Having worked with Mark for a year at Davies, I cannot recommend him enough as a .NET developer. He is one of the best developers I have had the pleasure to work with. His understanding of the technology and how to apply it in the real world is exceptional.
I worked with Mark for a client in Kainos. He is hardworking and dedicated to his work, keeps striving for excellence and motivates and helps others to do the same. His willingness to go the extra mile was always appreciated. He has great technical skills, an eye for detail, and a great sense of humour. He is a good team player and a strong contributor — a good professional to work with and highly recommended.
I worked with Mark on a client delivery for over 6 months. His excellent communication skills meant the team were always informed as to the status of Mark's work. Mark worked both independently on development tasks, as well as pairing with team members — in both situations the work produced was of consistently high quality. Mark's experience and pragmatic approach meant he was a very valuable member of the team. I highly recommend him.
