Vasile C.

Ruairi was a great dev to work with. His attention to detail and focus on quality were pivotal to his day-to-day work. His technical background and experience contributed substantially to the stability and quality of the mobile app we worked on. Could always rely on Ruairi to deliver on time and with professionalism. Defo recommending - I'd work again given the opportunity.

Steve McGregor

Ruairi is a very likeable character and blends well into the team very quickly, adding value from the start.
