I have 14 years of IT experience in the entire SDLC. I am a quick bug fixer and quick stand alone module/program/tool developer using PERL/JavaScripts/UnixShell Scriptings etc., on Unix platform having Oracle/MySQL/DB2/Sybase et., as databases.
I have fixed so many similar kind of bugs in PERL and Javascripting environment. I think this work can be done withing 3 to 5 working days.
