20 Minute tour of GPG (2015)

These are a small set of slides for quick workshop that I gave to introduce a group of people at Whitesmith to GPG and some encryption techniques.

If assume that the reader doesn’t know nothing about the subject and needs to protect files or messages (e-mails), either in transit or at rest.


Managing Secrets (2017)

In this presentation was given on the 5ª edition of the Madeira Tech Meetup and is a brief introduction to a real world problem for many companies as they grow, which is to manage a large number of secrets used by many agents.

In the presentation I try to focus on the area of software development and tasks related to the operations teams, so I picked Vault as a possible solution for this problem and made a demo of a real world scenario.


Re-Decentralization (2018)

A very small presentation I gave during a lunch break at work, to introduce a few projects that join federated networks and represent good alternatives to popular centralized services.

On the second part a few suggestions about open decentralized protocols, that developers can use to make their applications part of these networks.


HTTP Security Headers (2020)

This presentation was given on the 19th edition of the Madeira Tech Meetup and is a walk-through the existing and upcoming HTTP headers that can help developers secure their website and their users.
