Web Application Security for the Everyday Software Engineer
Gain insights into enforcing web app security best practices, such as HTTPS, defending against XSS and clickjacking, managing HTTP cookies, and warding off DDoS attacks.
Alessandro Nadalin (who likes to go by "Alex"), is a seasoned technical leader who pays a lot of attention to enterprise patterns, methodologies, communities and (everyone’s) personal development: with 10 years of experience on his back, he heavily focused his attention towards agile practices, patterns of enterprise application architecture, leading mid-sized development teams and managing complexity in distributed systems. A forward-thinker by nature, he still loves to get his hands dirty with code, or testing new platforms: he's quite active on github and, from time to time, blogs in his own little place on the internet. He's been involved in projects for governments, mainstream companies such as Samsung or Nissan and pioneered the technology scene of e-commerce platforms in the Middle East: when not working, you can find him speaking at some conference, blogging or grabbing a bite in the old side of Dubai.
