Paulino Calderón Pale (@calderpwn) lives on a Caribbean island in Mexico called Cozumel. He is the cofounder of Websec, a company offering information security consulting services in Mexico and Canada. He learned how to program and administer IT infrastructures early in his life, and these skills came in handy when he joined the information security industry. Today, he loves learning about new technologies and penetration testing, conducting data gathering experiments, and developing software. He also loves to attend technology events and has given speeches and held workshops at over a dozen of them in Canada, the United States, Mexico, and Colombia.

In the summer of 2011, Paulino joined Google's Summer of Code event to work on the Nmap project as an NSE developer. He focused on improving the web scanning capabilities of Nmap and has kept on contributing to the project since then.
