I have written more parsers in my life than I had crushes in my High School. In fact the last project I completed here on freelancer is a parser, should reflect in my history by the time you see it.
I have worked on SLR parsers, LL(1) parsers (also called recursive Descent) , LR 1 parsers etc. I have worked with parser generation tools like LEX , YACC (bison) as well.
Point is I can do this, and that too with a hell of an expertise. Let me know how I can help you.
Thanks Man
