I have over twelve (12) years of experience in high-tech, all of which have been spent in computer security and information security, working in several different areas and roles.

Also, I have completed some researching work on:
  • Permutation Oriented Programming – a completely different and powerful approach to research and analyze vulnerabilities and which can be applied to both offensive and defensive approach.
  • SQL Fingerprint powered by ENG++ Technology – a tool designed to perform version fingerprinting for Microsoft SQL Server 2000, 2005, 2008, 2008 R2 and 2012, as well as capable to describe the patch-level for them.
  • T50: an Experimental Mixed Packet Injector – a tool designed to perform stress testing on a variety of infrastructure network devices, covering some regular protocols (ICMP, IGMP, TCP and UDP), some infrastructure specific protocols (GRE, IPSec and  RSVP) and some routing protocols (RIP, EIGRP and OSPF).
  • Inception: Client-side vulnerability under the microscope – a deep dive experience on a reverse engineering for a client-side vulnerability, showing a full process to start a vulnerability dissection, which resulted in a change of CVE-2008-4844.
As a sought-after speaker, I have presented to industry professionals at conferences, such as:
  • IME Cryptology Week (2000/2001)
  • CNASI (2000/2004/2005)
  • Security Week (2002)
  • Gartner (2002)
  • CONIP (2004)
  • SERPRO/TIC (2006)
  • ITA SSI (2006)
  • H2HC (2006/2009/2010/2011/2015)
  • FEBRABAN CIAB Workshop (2009)
  • PH-Neutral (2011)
  • BSidesSaoPaulo (2012)
  • Silver Bullet (2012)
  • YSTS (2013)
  • BSidesLatam (2016)
