Оксана Костенко

I have 7 years of experience in commercial web development with different technologies on different projects, with various frameworks such as React.js and Angular, I have mastered many technologies including 3D and webRTC. Also in the distant past, I worked full-stack developer, so I have a clear understanding of how the backend works and how it relates to the front end, so everything is possible for me.
