Testimonials
Don’t just take my word for it – here’s what past clients and colleagues have to say:
★★★★★
I worked with David at a digital agency between 2018 and 2020, and all you need to know about David is that at our annual awards at said agency, there was the David Allsop Award which went to the person who had logged the most billable hours for clients, it was never even remotely close! Fun to work with, a hard worker (the hardest some would say), and all round great guy to have in your team. Can offer a wholehearted recommendation for David
Lorcan F

David was a coding machine in the time I worked with him. There was no problem too complex or solution too obscure that he couldn’t figure out. fuelled by tea and cuppa-soups he would make any solution work and computers and code bend to his whim. One of the best developers I have ever had the pleasure of working with and could always teach me something new, even if I thought I knew it all already. I aspire to be as skilled and knowledgeable as David in any area of work I come across. He would work tirelessly to complete any challenge put to him and would get it done in record time and then act as if the solution was as simple as 1 + 1.

I had the pleasure of working with David for – I think – for the best part of 3 years at Boom. Not only is he one of the most conscientious and gifted devs I know he’s also the only person I know who let a joke linger for 2 years before delivering the punchline on his last day. His problem-solving skills are second to none and he brings a huge amount of knowledge to every project he works on. And we worked on many. I would never have any reservations in recommending David to any of my clients – present or future.

I worked alongside David for several months in 2017 on an ecommerce project. David is a knowledgeable and reliable developer who takes pride in his work. David has a deep understanding of the web development domain and was always happy to assist me in learning when I was new. An example of this was teaching me about WordPress plugin development and how different hooks can be utilised. I thoroughly enjoyed working with David and would recommend him as a great addition to any development team.

I highly recommend David for his strong attention to detail. His meticulous approach to tasks and projects ensured timely, accurate and high-quality results each and every time. Not only was David a pleasure to work with, he also brought lots of great ideas and a fresh approach at difficult times, nothing was too big or small and internal barriers, new systems never fazed David.

★★★★★
David was my line manager at arco for around 1 year. Even in that short space of time he provided me training in all aspects of digital, such as Web development and design, digital marketing, content management, SAP Hybris, copywriting for Ecommerce and Adobe CC Suite. David was always somebody who lead change from the front, backed up by his technical expertise. He was an individual who could navigate uncertainty, inspire innovation, and adapt to change. It was a pleasure working with him and I would do so again in the future.
