Lately, he has delved into alternative programming languages (Kotlin, Lua, and Nim) and marketing.
Zacharias the writer
Zacharias is big on writing and blogging. For the past few years he has been authoring technical books in Technics Publications, with “The Data Path Less Traveled” being his most recent one. Most of his books, including this one, are accompanied by code and hands-on examples to make the topics covered more practical. Parallel to this, he has also self-published a sci-fi novel, “I, AGI: The Adventures of an Advanced Artificial Intelligence” which is available on Amazon/Kindle. Beyond book-writing, Zacharias maintains a data science and cybersecurity blog, Foxy Data Science, and he has been a guest blogger in various relevant blogs. Most notably, he has contributed to the AIgents data science blog, an educational site for data science and AI professionals. Recently, he has also become a moderator of the community aspect of that platform (aka, Data Champs).
Zacharias the podcaster and videographer
Since early 2022, Zacharias has experimented with podcasting too, to educate others on the ways of privacy and analytics. Without getting too technical, he explains key concepts for privacy-related topics, analytics, and the intersection of these two fields. The podcast consists of interviews and solo talks and has something to offer to professionals of all levels. Some episodes focus more on the business side of things, while others on more technical aspects. All of them, however, provide actionable information that can help you develop a privacy-oriented mindset that you can apply to your everyday life. Check it out on Utreon. Parallel to the podcast, Zacharias has delved into the creation of video material. This includes educational videos available on this site, all the video material of an AI course for the Beyond the Horizon International Strategic Studies Group, as well as a few promotional clips. The latter involves promos for his various works as well as various other things, such as some companies and the AIgents platform.
