Jamie is an absolute Rockstar. Within a week of him working with us, he had already identified five different areas for improvement, given two inspiring talks, and created a handful of engaging demos, all leading to almost immediate ROI.

We engaged Jamie to augment our existing team to overcome some real challenges faced when we inherited a failing product from a different supplier. Jamie worked diligently and meticulously, making a real difference in our plight to overcome these challenges and rescue something that now provides significant benefits for our customers

Without Jamie my podcast wouldn’t be running at all, that’s the simple truth of the matter. The amount of work he takes on for the production of my podcast makes him a no brainer choice and I’m positive the success of my podcast is in no small part due to fantastic quality of his work. Not only that Jamie is friendly and helpful always taking the time to explain to me the choices available in any given situation allowing me to make timely and informed decisions that have improved the quality of the outcomes of my work. Don’t sleep on the opportunity to work with Jamie!

Working with Mark and Jamie has been brilliant. They make everything straightforward, and in our meetings they have always been knowledgeable and prepared for any eventuality. I felt like they cared about the unique perspective of my podcast, as well as my time."

Andy Norton

Andy Norton

Software Development Manager at FootAsylum

Jamie came in as a software consultant, working alongside our Platform team to coach them on .NET best practices and get them working properly in pairs and following SOLID and DRY etc. During his time he helped with our microservices architecture in Azure, working out some of the high-level flows and then working to improve unit test coverage and integrations with 3rd parties. He has tons of knowledge and is a real asset as a consultant, and would sit with different devs helping to un-block them. I’d have no problems recommending him for work in the .NET/Azure space.

Over the years of producing my podcast the editing of each episode was the most time consuming. I’m not a sound engineer and its not skill that’s easy to pick up, but Jamie was able to provide the skill set for me. He took the pain out of producing consistently high quality audio, giving me more time to focus on talking to my guests and making my shows.
