Hi, I’m Dan. I’m a senior engineer and a problem-solver by nature, and I enjoy making tech more efficient and streamlining it for both developers and users. I analyze systems the way I would at work—always looking for ways to optimize them. I’ve given talks on 3D printing and stay active in developer communities online and in person. I’m passionate about electronics, robotics, 3D printing, and trying new hobbies. Recent interests include making bean-to-bar chocolate and handcrafting chain mail. In my free time I love hands-on personal projects and learning new skills.…Hi, I’m Dan.
