Freelance programmer and web developper

I have been programming in PHP for over 10 years, lately also in javascript/jQuery. I worked with MySQL most of the time, but also with PostgreSQL, including stored procedures, views and optimizing indexes. I know a lot about HTML/CSS. I can integrate anything with anything else, as long as there's some documentation for it :-) - numerous payment gateways (PayPal, Moneris, RBS WorldPay, Beanstream, InternetSecure, Global Payments, Braintree) - Kraken API - Google Maps API - OAuth / Google Calendar API - NGN (Golf Canada) I've written / modified plug-ins for Drupal, Joomla/Mambo, WikiMedia, ExpressionEngine although I've always preferred custom applications over CMS. Over the last two years I've been using framework Nette which totally beats CakePHP or Smarty with custom MVC that I'd been using before. I'm willing to be paid in bitcoins. Web security is my hobby (injection exploits, XSS...).
