Hello, I've read your project description and I understand that you're looking for someone to build a website to compile LESS, SASS, Jade, YAML, etc. For this job, I'd suggest to use NodeJS with ExpressJS.
My name is Duc Nguyen, and I'm a Web Developer with more than 6 years experience working with NodeJS,YAML, Twitter Bootstrap, etc. Also, I'm a fulltime freelancer so I can start the job right away, and right now I'm having 100% completion rate because I'm committed 100% to a single project at a time.
Hope to hear from you soon.
Best regards.
