Computer hacker turned entrepreneur. I am a managing partner and one of the co-founders at Blaze Information Security, a provider of cybersecurity assurance, penetration testing and application security to enterprises and startups with strong focus in Europe, United States and Latin America. Contact me to discuss how we can help your organization protect from cyber threats. My background is as a security engineer with particular interest in penetration testing, threat modeling and vulnerability exploitation, with nearly two decades of experience under my belt. In the past I discovered previously unknown security vulnerabilities in several popular software (published CVEs include: CVE-2003-0277, CVE-2004-1390, CVE-2004-1391, CVE-2004-1683, CVE-2004-1682, CVE-2004-1681, CVE-2005-2725, CVE-2006-4907, CVE-2007-5805, CVE-2019-10044, CVE-2019-9970, CVE-2019-15237, CVE-2019-15103, CVE-2020-13431, CVE-2020-14197). Eventually I present at conferences, having participated as a speaker in Chaos Communication Camp, H2HC, Ekoparty, CONFidence, Talk 'N Roll, Nokia Test Dive and others. I was never into certifications as I believe most of them are of low value and nothing but a cash cow for accreditation boards, but some of them are challenging and worth taking; I hold OSCP, CREST and that's pretty much it.
