I have been developing software in different languages for past 15 years. While my strong grip is in web development with PHP, jQuery, Bootstrap and MySql as database, I also like making tools in Excel/Access VBA, Perl, Python and Visual Basic. I have numbers of online and offline tools available for public demo, which can be provided upon request. My recent engagements include Android Development with one App listed in Google Play Store with 20,000+ downloads.
I work alone and always bid on projects that I am confident of delivering after a thorough scanning of project deliverable. Also before final acceptance, I'd prefer to have a detail discussion with the requester to avoid any misunderstanding and clarify all grey areas. And lastly, I never ask for any interim milestone, you'll pay once I deliver full project.
