Callum is undoubtedly an excellent engineer. He was also a great mentor to me while we worked closely in the same team at Nutmeg. I particularly appreciated his incredible attention to detail and enduring emphasis on quality, well-architected front-end code.
He is also a great communicator, able to explain topics clearly and concisely, as well as being able to debate his viewpoints calmly and objectively. This all made Callum a valuable teammate.
I have learned a great deal from working with him, and much of what I have learned I hope I will continue to apply on a day-to-day basis throughout my career. Thanks, Callum!

I had the pleasure of working with Callum on the Core UI Architecture team at KAYAK.
Callum is a stand-out developer and an all-round pleasure to work with. He has a "can do" attitude, and takes thoughtful, future-focused approaches to architecture and solution implementation with exceptional attention to detail and quality. He is driven and motivated, and possesses exceptional knowledge and interest in internet-related technology used across the stack.
I was delighted to have Callum join the team in the early stages of a high-stakes project to develop a full-stack framework for web resource optimization and management through integrated development processes. Callum's input was integral to the completion and delivery of a high-quality, thoroughly tested enterprise-level framework, which is now used across the board at KAYAK by all frontend engineering teams.
I would highly recommend Callum as not only a solid frontend engineer, but also a highly capable solutions architect.

Hands down I would not be the engineer I am today if it was not for Callum's thoughtful, considered and quite frankly, brilliant mentorship. I worked under Callum for nearly two years at Commusoft as a junior engineer, where Callum's expertise in design, user experience and programming gave me the head-start in software engineering that I needed.
I worked with Callum primarily in the front-end side of a complex web application, however, Callum is an equally talented product designer and full-stack engineer, proven by his amazing work for Commusoft. He fully understands the complexity and trends in front-end software engineering - an example of which is his open-source library immutable-styles which solves one of the very real problems in front-end software engineering right now.
Callum's ability to unpick a particularly difficult problem is unparalleled, and he consistently operates with a user-centric attitude in his solutions and meticulously delivers with a focus on visual and user-experience design.
I cannot thank Callum enough for everything he has taught me, and I wish him all the best in his future endeavors.

Callum is a fantastic designer, he has an incredible eye for even the smallest detail and a great sense of style and design. He has a brilliant understanding of how a user will experience his work, from the simplest button to the most complex animations. He loves what he does and it has been a real pleasure working with him. I'm incredibly excited about the work we're doing together and really pleased he's joined the team.

It has been a pleasure working with Callum over several years. During this time he has worked on a number of projects for me: from micro apps to enterprise applications. The focus and passion Callum has for web development is reflected in his work - someone I'd call a true craftsman. I highly recommend Callum.

I have worked with Callum over the past 2 years in relation to front end development work and have to say it’s been a great experience thus far. From pixel-perfect web development to input on strategic layout and functionality, Callum has always delivered more than what was expected.
Callum's work is second to none. As a designer, knowing that I will receive exactly what I lay out gives me the opportunity to push the envelope in terms of what I can do and makes me a better designer in the end. Highly recommend working with Callum.

Callum has done an excellent job on Meta Trails, his enthusiasm, ideas and delivery have been top notch. He grasped Ruby-on-Rails very quickly and we were very impressed with his abilities to take ideas and deliver a working product.
