The largest UK owned pizza chain

Pizzas. Lots of pizzas. I designed, developed, and maintain the Pizza GOGO website and in-store EPOS that powers 120+ stores nationwide.

Working closely with management and being directly involved with almost all aspects of the digital side of the business for both B2C and B2B operations has helped both the business and myself to grow.

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.

Brighton property

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.
