Dan Cook

I have a long-standing passion for coding, and have received great feedback as tutor & mentor over 10+ years as a Software Engineer. I have an expert mastery of Javascript, Typescript, C#, GIT, CSS, HTML, and have implemented solutions at all levels of the tech stack. I feel strongly that software is built for people, and not the other way around: I strive to provide solutions that meet people where they are. As a programming language enthusiast, I have explored many languages & paradigms, both in terms of practical use and underlying mechanisms. This has given me a uniquely strong ability to: implement solutions that closely match human mental models; understand solutions apart from their coded form; spot incidental complexity in code; deconstruct and re-implement complex code-bases (e.g. when migrating legacy software). As a tutor and mentor, these experiences enable me explain things in human terms, and empathize with the gap between technology and the human mind. My favorite experience as both a software engineer and mentor, is that spark of discovery or understanding while walking someone (or vice versa) through a problem or explanation. Other interests: Piano, Stargazing, Hiking, Camping, Yoga, Mindfulness, Reading, Origami, Retro gaming, Sci-fi, Horror, Dad jokes, Playing with my kids & my dogs.
