Fionn Kernan

I build websites and software in Bangor, Northern Ireland.

Mostly for local businesses and clubs. Right now that includes RefYou, a replay system I started for grassroots football and have taken from an idea to real matches this season.

Work

RefYou

2026

Instant replay for grassroots football. Four phones round the pitch and a tablet on the sideline, and the referee can watch any moment back from every angle while the match is still going. I design it, write it and run it at the matches myself: the app, the server that connects the phones, and the footage afterwards.

The same second of a football match seen from four phones, one at each corner of the pitch
One second of Bryansburn 2nds v Ballykeel, from the four phones.

Nextfield

A recruitment and training platform for agricultural businesses across Northern Ireland, with a custom enquiry and application flow, built to grow with the business.

Concept sites

Two sites I designed to show how a local business can be presented clearly: Northshore Electrical, for an electrician serving homes and commercial clients, and Oak & Iron Café, a welcoming site for a neighbourhood café.

About

I'm from Bangor. I like building things from start to finish: the design, the code, and turning up on the day to make sure it works. That is how RefYou went from a few phones on tripods to being used at Bryansburn Rangers matches, where its footage has already been used in a formal appeal.

When I build a website for a business I plan it around what the business needs the site to do, keep it simple, and hand it over so you can update it yourself without needing me.
