Hi! I have 15 years of experience and I'm specialized in backend implementation (business and data layers), APIs (WSDL and REST), file parsing (CSV, XML, Excel, etc), regular expression, among others. In terms of web user interface, I have good knowledge of javascript and jquery (including ajax/rest calls). I'm also familiar with HTML and CSS, but I'm not a designer.
If you need someone with strong knowledge of backend implementation, I'm your guy.
Should you have any questions, please contact me.
Regards,
Daniel
