Hi there My name is Rafał, I have five years of corporate career as FullStack software developer .Net and Angular. I'm very ambitious person that’s why in three years I was able to jump up four times from intern to a "senior" position. 

I feel I have reasonable knowledge about what I'm doing. I have delivered many complicated (not to say hard) tasks during my career. I have completed many training, read many books watched hours of videos. Having this experience and knowledge i have decided to start teaching others. 

Teaching force me to dig even deeper into the field and stay up to date. I have started with internal trainings on site and online, all went very well and was scored above 4 on 5. 

Now I'm going further and make the workshops commercially. I'm looking to gain recognition in the community, money plays only second role. I can make training in Polish and English. My main points of interest are Angular, .NET CORE C#, Clean Code and soft topics like productivity.
