Summary


I'm a full-stack web developers with many years of experience working with different teams and technologies. Through years I had to wear many different hats - from frontend developer to Linux server sysadmin.

I've been working remotely for more than 6 years and I know the power of good communication.

I'm not afraid of working on the legacy code, I still maintain an old platform written in PHP5. So if you want to free up your development team from legacy burden I'm the person you want to hire.
