Profile
I started developer career in the end of 2013. I successfully fixing bugs without recurrence, write the code clearly,
if possible - without unexpected turns, and practice careful refactoring. Personally familiar with the debugger. I like
accuracy in the entity with behaviors, and always avoid data processing into implicit places (view, getter, etc.). I
notice when the code asks for a builder connection, a bridge split, or an entity factory to be created. I also have
experience developing a state machine that decorates the behavior of an object based on the selected
strategy and state. I know how to implement a little more patterns, and for everything else there is Google. I
sacredly honor and observe the principles of DRY and YAGNI, remember KISS and I try to do everything
SOLID. Also, I always document with auto-markup.
