Colleagues describe him as "Tim is an absolute professional and supremely talented. I 'inherited' him when I joined the Concept Farm and I knew immediately that he was going to be a key asset for me in further building out the digital capability. Beyond his technical skills and appetite for learning and problem solving, Tim is simply a pleasure to work with. His co-workers say it. His clients say it. I would recommend Tim without hesitation. And I will continue to try to hire him back wherever I go." and "To call Tim a Web Developer is putting him in too general of a category and doing him a disservice. He's a specialist. I had the pleasure of having Tim on my team for two years and I'd like to think we produced some fine work together. He understands frameworks and platforms and what he does not know he quickly learns. He has an even keel personality under all circumstances. Even with a ridiculous timeline he delivers. I look forward to working with him again."
