I'm security researcher acknowledged by U.S Department of Defense for disclosing number of vulnerabilities on DoDs systems via Hackerone platform. Curently working as private contractor @ I've had pleasure of auditing security of Nebraska School Activities Association(NSAA), Iowa Highschool Athletic Association(IAHSAA), Native Roots from Colorado, Enovos Luxmeburg, Tracorp, Browzzer , Liontrust, Czarnikow , Publitas & many more. My core competency lies in performing black and gray box testing, on the live web applications/networks or in lab environments.I am familiar with all common attack vectors and mitigation techniques, aswell as finding unknown to public exploits known as 0days in web applications. Eventhough most of my work is confidential I can share vulnerability assessment sample.

Penetration tester

Nov 2015 - Nov 2015 (1 month)

I've been contracted to conduct penetration test on (setup in lab environment before being launched). Website was based on SugarCRM, and was mainly used by employees. Thus security was a main concern. I've found 2 XSS(Cross-Site Scripting) vulnerabilities (1 stored and 1 reflected) wich would lead to privilages escalation in the system by malicious user/employee. I have also done re-test on a live version of a website ().
