Common Web Security Issues and Tips on How to Overcome Them

When we are talking about web, security is not for granted. Every day systems and data gets compromised or destroyed both as a result of attacks and negligence. On these slides I cover many overlooked web security issues when designing web applications.

Open source projects I have contributed to

Go socket.io client

Go socket.io client forked from and heavily modified.


pseudoterm is a framework I created for running iterative programs programmatically with Go.
Tip: Google created a similar and better framework a few months after I released pseudoterm: Expect for Go


picel is a light-weight, blazing fast REST-ful micro service for image processing with a lean API. I created it for fun with the ideas of learning the Go language and solving the image processing problem on the web the way I find more appropriate. picel-js is its accompanying JS encoder library.


NodeGH is a GitHub command line tools by Eduardo Lundgren and Zeno Rocha.
I've adopted it by contributing with some nice features, fixing bugs, and so on.
Install it now with npm install gh -g


AlloyUI is a framework built on top of YUI3 (JavaScript).

My old personal projects


Vehikel is a car ad web service.


accidents was a statistics project written in R. I gave to it all the attention a temporary, 1-month classroom project doesn't deserve and it turned out cool (in terms).


Plifk is a file sharing web service which uses several cloud computing technologies.


to-post.it is a minimal posting service Twitter users can use to post things, like a blog or pastebin. The previous Medium!


trazqueeupago.com is a social-based commerce web service that allows Twitter users to quickly tell what they want to buy/sell based on their location / direct connections. It's only available in portuguese.

My other works


Cahier is a B2B SaSS corporate social network. It's built by the startup MGR. I've worked on it as a backend engineer both with PHP and JavaScript (Node.JS). The most interesting thing I've built there was a Facebook-like chat system on top of socket.io.

We should forget about small efficiencies, say about 97% of the time: premature optimization is the root of all evil. Donald Knuth
It seems that perfection is attained not when there is nothing more to add, but when there is nothing more to remove. Antoine de Saint Exupéry
