ABOUT ME
Experienced Blazor, .NET Core developer (5+ years) and coding teacher
Experienced Blazor, .NET Core developer (5+ years) and coding teacher
I'm a NET Core developer to the bones. My co-workers always describe me as a having integrity, reliable person and I am able to create a trustful environment where candid feedback can flow freely.
I took the biggest step from the last job, where I was hired to review and audit the code and the technical solution of the product under development. My contribution to this project was pushing the product from an intentional state into something that created pleasure and happiness for nearly every stakeholder.
In addition, In my free time, I'm engaged in an open-source community. My contribution ranges from explaining, PR reviews, fixing bugs, and creating new features with the result of creating one of the most loved solutions in that space (or niche).

Do you know the difference between int and Int32? I've asked myself this and many more questions during my work with C#. Answering these questions and thousands of hours working with it to create software, have led to a deep understanding of it. what is possible, what is sometimes a bit more complicated and how it can be used to write efficient source code.

Blazor is awesome. NET devs, do not need to leave their comfort zone and stepping into the JS zone to deliver interactive web experiences to customers. We can do it with the known great and efficient tools we know, the libraries we love, and with the right component library, we can create awesome applications without a deep understanding of HTML, CSS, or JS. What could be more promising :)
I've worked with Blazor since the earlier preview version and haven't stopped since then. I'm a contributor to MudBlazor (https://mudblazor.com/) to help create more and more components to simplify the life of other Blazor developers.

I've worked on some greenfield deployment to start new systems with enough complexity that DDD pattern and practice have been a good fit.
These projects include working CQRS and Event Sourcing. As Event Sourcing Database, I've worked with Azure Cosmos DB and Event Store.
I love DDD. I regret not being exposed earlier in my career, and I'm proud to develop a DHCP Server that uses DDD. It was so much easier than the first CRUD version I had built.

Like many developers, I started my career and was just happy that when things worked. "Worked" means I've tested it manually and hoped that further changes wouldn't break something. This approach reaches its limits very fast, and I've spent more time on fixing than developing.
After learning the concepts behind TDD and applying them to my daily coding routine, I've become a much better developer. TDD done right leads to so much more resilient architecture. A huge benefit is that I can sleep without the fear that any application will break, and I've to fix it in the middle of the night.

To cross the distance from pushing changes into a repo and having a running system, all it takes is just a pipeline, right? Well, that is the promise and it's partly true, but it takes so much more knowledge around the involved technology to do it with confidence. I've worked on some projects to building such pipelines and the infrastructure behind them.
It was not easy for me to learn these things, but having such a working, automated system, create so much more confidence in running and developing the system, that it was worth it.
