I am a Professional Full Stack Developer with over 15 years of hands-on experience in software engineering, system design, and artificial intelligence.
I’ve worked across frontend, backend, DevOps, and AI, building enterprise-grade systems for real-world applications — from large-scale microservices to cognitive AI platforms.

I’m passionate about teaching the real, modern way of coding — combining deep technical foundations with today’s most advanced technologies: Generative AI, Agentic systems, RAG architectures, cloud automation, and intelligent DevOps.

Whether you are a beginner exploring your first “Hello World,” a professional improving your stack, or a researcher/developer exploring AI systems, I can guide you step-by-step — conceptually, practically, and strategically.

Docker is an essential tool for any developer nowadays. It allows flexibility and speeds up development.
Whether you would like to start learning containerization or you would like to take your knowledge to the next level, I can help you. Docker is a great tool to not only deliver software but also to play around with different technologies and test multiple releases without burdening your local environment.

Do you want to learn how to program desktop applications in Java, C language, C ++, CSharp (C #), PSeint, Visual Basic .NET, Macros in Excel?

Do you want to learn how to program mobile applications in App Inventor 2?

My teaching methodology is Project Based Learning (PBL).

In this way, to build an application, I will teach you that the really important thing before sitting down to code (by attempt and error) in front of the computer, is the analysis and design of the algorithm (which constitutes 90% of the success of the program to be implemented. ), for this, with an example from the real world, the construction process will be explained: 1. Example with data from the real world, 2. Collection of information on requirements (input data, calculations, output data), 3. Hierarchy of operators (mathematical formulas versus computational formulas), 4. Desk test on a spreadsheet, 5. Constants, variables and data types to use, 6. Algorithm construction, 7. Flowchart, 8. Desk test on paper, 9. Implementation of the algorithm in the chosen programming language, if it is in console mode, it is implemented directly, if it is in form mode, the user interface is drawn on paper (UX) first.

I've been tutoring for eight years, so I'm convinced that you can learn anything. Often all that is missing is a clear explanation that makes it clear step by step how and why something works.

Also important to me:
- Take away your fear of the subject
- Explain topics in an understandable way, gladly several times and in different ways
- Closing gaps in knowledge
- Create a relaxed learning situation
- Repeat what you have learned
