Testimonials and reviews
Mark is a great UX designer, and has three skills, which I believe set him apart from his peers. He is an extremely capable developer (PHP, SQL, HTML5, to name a couple), a very keen practitioner of user-centred (UX) design, and a fantastic people-person. The third skill is important to note, because in addition to developing, and then designing great user-interfaces for commercial applications, he also does a lot of ethnographic work, in order to observe and understand how people currently interact in a given commercial context.
Pete Pavan, UX, UCD, and User Research specialist

#slices4nurses
We hurriedly put together a campaign in 2020 during the start of the Covid-19 pandemic called #slices4nurses. This created an amazing show of support by the Pizza GoGo community. For several days this was an all hands on deck round the clock response for our team at head office to show support for our NHS.
The team worked hard to arrange hundreds of free Pizza deliveries to various locations across England & Wales - from Hospitals with staff on the front line to Ambulance Stations and even Schools that are open with kids of our beloved NHS staff.
Rapidly growing holiday let PropTech business
My Getaways (previously Brighton Getaways) is one of those disruptive PropTech businesses you keep hearing about.
I was responsible for building the web presence and all technology of this online based PropTech business. With a small focused team we built a property management system (PMS) business from the ground up which is now one of the largest in the South East.
I solo designed and developed both the B2C front-end and PMS back-end on a tight budget with UI & UX considerations. This included integration with automation systems into booking channels, digital smart security, guest communication systems, and a whole lot more. I also suggested/influenced the original design style of the physical print media, such as brochures.
