About

I am an AI/ML engineer with 10+ years of practical experience, currently working as a Senior AI/ML engineer at MSD Czech Republic. Previously, I have been part of large companies such as Amazon and Seznam.cz, as well as local startups. I also have experience collaborating with universities in Czech Republic and Spain. I have always enjoyed and found fulfillment in knowledge sharing, and I have been teaching Python to beginners for 5+ years. I have also created several lectures and workshops with the goal of passing on my knowledge to others. I believe in a friendly and individual approach that helps students achieve their goals faster and more efficiently.

Mentoring

Over the past few years, I have had the opportunity to work with more than 300 people who wanted to learn Python – from complete beginners to experienced developers who wanted to deepen their knowledge. This has helped me understand what most often slows them down in learning and how to work with it. One thing has shown up again and again: everyone learns differently. Some need more time on the basics, others want to jump straight into more complex projects. And this is exactly what's difficult in group courses – they are not built for individual pace and needs. That's why I offer one-on-one mentoring, where I fully adapt to you. Together we will set goals that make sense, and work on them step by step. I will help you not only with understanding the language and programming thinking, but also with practical things like job interview preparation. Whether you want to just start with Python, or move further in your career, I'm happy to help – in Czech or English.

Mentoring Areas

How can I help you? I specialize in practical programming and modern AI technologies.

šŸ Python with a friendly approach
