Denis Panjuta. Born in Russia and raised in Germany, Denis Panjuta's journey is a testament to the power of perseverance and the pursuit of passion. The youngest of three siblings, Denis was introduced to the world of computers at the tender age of 11. This early encounter sparked a fascination that would shape the course of his life. Despite the initial struggle to learn Java at 17, Denis was not deterred. He recognized that the outdated resources he was using were a barrier to his progress. It wasn't until he was 23, armed with a fresh mindset, up-to-date books, and the vast resources of YouTube, that he finally broke through the barriers and became a software developer. Denis pursued his higher education at the University of Applied Sciences in Konstanz, Germany. It was here that he began to merge his passion for coding with a newfound interest: teaching. His bachelor's thesis, a series of coding tutorials, not only won him the award for the best thesis of the semester but also paved the way for his career as a coding instructor. Today, Denis is a respected instructor in Android App Development and .NET Programming. His love for teaching is evident in his approach. He believes that "sharing knowledge multiplies the knowledge," a philosophy that has guided his career and his life. Outside of his professional pursuits, Denis is an avid gamer, skater, and hiker. His love for these activities is a reflection of his adventurous spirit and his constant pursuit of new challenges. (edited) Denis's journey took a new turn when he decided to write a book. With a large audience of subscribers on YouTube and Udemy, he saw this as the next natural step in sharing his knowledge and passion for coding. His vision is ambitious yet inspiring: to teach coding to 10 million people and to improve the world through the software developed by his students. This vision, coupled with his dedication and passion, makes Denis Panjuta a beacon of inspiration in the world of coding education.
