Hi there,
First of all, I apologize for bidding as you prefer someone from North America but we don't have much time difference and I'm almost always online/in front of the computer.
I'm a full-stack developer and my main focus is Meteor for the last two years. Besides that, I've been studying and working on user interface and especially user experience design.
For front-end, I can say I'm extremely good with HTML, HTML5, CSS, CSS3, LESS, Bootstrap 3, jQuery, jQuery-ui. I'd suggest designing the UX individually for mobile, tablet & PC though...
Anyway, kindly check me and my team's reviews here and let me know if you have any questions. I can show you better examples of my work if you get back to me as I don't like publishing everything to our portfolio here.
Best regards,
Luna
