Dan Smith is a Outside Consulting Engineer and Expert Witness at Barr Group - Software Expert Witness. Colleagues describe him as "I cannot recommend Dan highly enough if you need an expert in his field. I worked with Dan on his first assignment as a testifying expert, and he was already incredibly polished. Dan is first, and foremost, and expert in software engineering, and he truly knows his subject matter from years of having worked and taught in the field. But equally important, he is the rare expert who can explain his technical expertise and opinions clearly, and in an engaging and personable manner. Dan can completely dismantle an opposing expert's opinion while being entirely congenial. Dan is also an extremely hard worker, who cares deeply about doing his job well and reaching defensible opinions that he can support with evidence. He will not offer an opinion that he cannot back up, and works very well a a member of a team with attorneys and other experts. I truly enjoyed working with him, and I would not hesitate even a second to hire him again if I have a need for an expert in his field." and "I have had the pleasure of working with Dan for several years on multiple projects that included firmware development, embedded systems training course content, and embedded system security. His attention to detail and innate ability to understand client requirements is consistently at the top of the embedded software consulting field. In addition, Dan is an exceptional instructor/speaker with a unique gift to capture and maintain the interest of clients, students, and trade show attendees. His software development work is always exceptional in terms of analysis, design, implementation, and documentation. I would highly recommend Dan to any firm that is looking for a seasoned embedded software engineer with top notch skills in system architecture, real-time operating systems, coding standards, security, training, expert witness, and communications."
