As a traveling software developer, mentor, and author, my career has led me to nearly 20 countries across four continents and a variety of cultures.
I have extensive experiences in planning and delivering trainings, workshops, speeches and keynote speeches on a wide array of software topics, ranging from programming languages to teamwork organization.
I’m one of the highest-rated instructors on Pluralsight, one of the foremost international providers of video trainings. Some of my courses garnered hundreds of thousands of paying viewers, and my course ”How Git Works” stands out as the most commented- upon training on the platform.
I authored three critically acclaimed and commercially successful books. Both editions of "Metaprogramming Ruby" are widely recognized as indispensable resources for Ruby developers. "Programming Machine Learning" was lauded by a reviewer as a "Dragon Book for data scientists". I also contributed to the field through numerous magazine articles, including a popular monthly column.
I have decades of hands-on software development experience, spread across domains such as enterprise software, open source libraries, automotive, healthcare, large-scale web applications, and computer games. Notably, I contributed a key element of Hibernate, arguably the most popular Object-Relational Mapper in existence.
Much of my career has been devoted to educating others through training, mentoring, and coaching. I have guided teams and entire companies toward adopting modern development practices. Being an early advocate and adopter of Agile methodologies, I have actively participated in related conferences since 2003.
