Paulino Calderón Pale (@calderpwn) is a very passionate software developer and penetration tester from a Caribbean island near México called Cozumel. He learned how to write code and administer IT infrastructures early in his life, skills that came in handy when he joined the information security industry. Today, he loves learning about new technologies, pen-testing, conducting data gathering experiments, developing software, contributing to the open source community, and speaking and giving workshops at IT security conferences.
In the summer of 2011, Paulino joined Google's Summer of Code program to work on the Nmap project as an NSE (Nmap Scripting Engine) developer. He focused on improving the web scanning capabilities of Nmap, and since then has produced over 30 scripts for gathering information and detecting and exploiting security vulnerabilities.
Paulino is the co-founder of Websec, an information security company focused on web security operating in México (http://websec.mx) and Canada (http://websec.ca), where they help companies in different industries secure their IT infrastructures.
