Hi,
I am very interested in your project.
Let me quickly introduce myself: I am a Senior Programmer Analyst with over 15 years of experience. I worked on large projects for different governments (Togo, Jamaica, Haiti ...), for International Organizations, banks and public administration.
I am currently a consultant for the World Bank.
I am convinced that I am the freelancer that you need because I am very comfortable with pure javascript, jQuery, CSS3 and HTML5 and I did several work like this before for different clients and even on Freelancer (you can check the comments for similar projects on my profile page). I even can go under the hood (server side) to propose the best solution.
While waiting to work with you, I wish you a good day.
Thank you.
