Good morning, I'm a frontend expert and I've worked with responsive frameworks before, like bootstrap, flatlab, wrapstrap, etc. I'm also a web designer so you won't have issues by working with me.
As long as I've more than 10 years of experience, I'm able to finish this project quickly. I'm also available 24/7 for suggestions or comments about the project.
Thanks in advance for taking me in consideration.
Regards
Xavier
