My experience ranges from building responsive web-sites that works well cross-browser to building services with embeddable JS-scripts and high-loaded backend. I'm flexible with my working hours and am happy to work closely with any existing freelancers you work with. I can: - create a responsive web-site - connect your site with any external API - create your open API for your needs - improve performance for your site or service - any front-end or back-end tasks - document my solution
