Joshua Willman is a software engineer with more than 12 years of experience developing applications in mainly Python and C++. His career has allowed him to participate in many different fields, from robotics, machine learning, and computer vision, to UI development, game development, and more. His first experience with PyQt was building an interface for simplifying the labeling process of datasets for machine learning. Ever since then, he’s been hooked! In recent years, his passion for programming and all things visual has allowed him to participate in numerous projects. These include designing educational courses for mobile robotics and computer vision using Arduino and Raspberry Pi, building GUI applications, and working as a solo indie game developer. He currently works as a robotics engineer, a technical writer, and a content creator (learning web development in his spare time in order to build his own platform, redhuli.io). When he’s not working, he enjoys tinkering on robotics projects and spending time with his wonderful wife and daughter. He is also the author of two books with Apress: • Beginning PyQt: A Hands-on Approach to GUI Programming (1st Edition) • Modern PyQt: Create GUI Applications for Project Management, Computer Vision, and Data Analysis
