Bottega IT Minds | Circle K

Well... somehow my story reached up to this point! I'm the trainer in the best training company in Poland - Bottega IT Minds, and active developer and architect in Circle K, working with modern and valuable solutions.
For some time I was coding without understanding how complex activity it is, now I'm modelling the solutions and implementing it, being fully aware of how frequent changes are and how simple they should be. I observe how cute, and secure the software can be, when designed, tested and implemented pragmatically.
I'm asking lots of questions to distil what is crucial, filter out the noise and build backend, frontend, architecture and... teams.
That way led me to Bottega IT Minds, where I can teach others, being among top mentors. Ones who taught me a lot before. Incredible, huh? :)
