Thomas has a lot of programming experience with different technologies and has talent to explain it to others. I started to learn NodeJS with a basic knowledge of JavaScript. Thomas helped me with explaining difficult concepts on simple examples, so it is easier to understand, especially when you are a beginer. He can answer almost all questions. We also try to answer questions together, so I can learn faster. I'm really happy to find such a great teacher! I learn a lot from Thomas and I can see my progress. Thank you so much for your explanations and sharing your experience with others! The lessons help me to understand new technology and improve my knowledge.
