Привет!
I've taken a look at your site and offer you the following changes:

I'm an independent front-end developer from Minsk, Belarus. I have 3+ years of experience with AngularJS and different (you might want to choose a different word than "different." "other" seems better) front-end tools.

I like to work in the team on teams of professionals developing large and valuable product[s] withusing modern technologies and effective development methodologies.

More info is in the (or you could say "my") CV
Remote front-end development on in AngularJS. You can hire either me personally me or a top quality front-end team managed by me myself.
Secondary Tools I've Worked With
It's best to write all titles in normal casing. I notice you have the first letter capitalized. This looks unprofessional, so consider it a suggestion. On a side note, I'm a front-end web developer myself. :P

Write Contact me for any questions, offers, etc.
Fyodor Khruschov was working has worked with me and my team on the Instituto Sawabona project from April to November 2014. He worked as a front­-end developer using AngularJS as the main framework of our application.

Fyodor is an outstanding AngularJS developer, always delivering quality code, well documented, and tested with super­fast speed (Consider rewriting this line unless it's a direct quote, in which case there's not much you can do... but it'd be a shame). His capacity to understand the requirements and implement them with alacrity made him my first option to resolve the biggest problems in with my projects.

Fyodor is also an easy­going person, always with having a good mood. His personality is calm and focused on results.

I strongly recommend him as an AngularJS developer for any kind of web application.

It's not bad overall, but it needs some work. Most edits are grammatical, but some are changed to sound more natural. I can see that you have trouble with particles. "a"," an", and "the" are very important.
