About

Hi there!

My passion is helping people through books and online courses. So far, I’ve inspired over 100,000 students worldwide.

My name is Károly Nyisztor. I’m a software engineer, online instructor, and author. You can find my courses and books on all major platforms, including Udemy, LinkedIn Learning, Lynda, and Pluralsight.

I’ve worked with companies like Apple, Siemens, SAP, and Zen Studios. As a software architect, I’ve designed and built several enterprise frameworks. I currently hold twelve patents related to inventions in the field of mobile computing.

After 18 years, I left the corporate world to start my own business. Since 2016, I have been fully committed to teaching.

I have worked with various technologies and programming languages, including x86 Assembly, C, C++, Java, Objective-C, Swift, Python, and Tcl. I have built several successful iOS apps and games that Apple has featured as “New and Noteworthy,” “App of the Month,” and “Best Travel Apps.”

I teach Software Architecture, Object-Oriented Programming and Design, Software Security, iOS Programming, Machine Learning, Swift and Python Programming, and UML.

As an instructor, I aim to share my more than 25 years of software development expertise to help change the lives of students throughout the world. I’m passionate about helping people uncover their hidden talents and guiding them into the world of startups and programming.

It Started With A ZX-Spectrum

Several decades ago, I got my first computer, a ZX-Spektrum. This is how it started, and programming computers became integral to my life.

As I got my hands on my very first computer, I knew programming would play an essential role in my life.
Fresh out of university, I started working at a big software company. Although I worked on great projects, I’ve never felt accomplished by doing the usual 9-to-5 work.

My side projects were the ones that made me feel alive; these hobby projects probably saved me from the burn-out most fellow software developers encountered during their careers.

I wrote three books, the first on the practical aspects of programming in C++. The second and the third book was about DirectX programming and shaders.

I started developing a 3D space adventure game called “The Gamma Project.” After a few months, the game looked promising, good enough to send out the demo to a couple of publishers.

It was 2005, and there was no AppStore back then. Only a handful of small publishers would consider publishing an indie game. Eventually, I realized that I wouldn’t get anywhere with my game. Those were tough times for indie developers.

In 2007 Steve Jobs announced the first iPhone, which had brought significant changes. The iPhone App Store opened on July 10, 2008, and changed the lives of many aspiring app developers, including mine.
I published my very first iOS game in September 2009. Since then, I’ve developed many apps and games, some of which (my Travel Assistant, GiftShopper, iSyslog) were featured by Apple and mentioned by prominent media outlets.

I started creating online courses in March 2016. I’ve published courses on UdemyPluralsight, and LinkedIn Learning. Teaching has always been my passion, and I’m happy to reach such a broad audience.

In December 2016, I quit the corporate world. I can now fully dedicate myself to creating courses and working on projects I’m passionate about.
