I have started as a desktop and backend C++/C# developer. While one part of me enjoyed creating programs, my other passion always was finding cracks and breaking things. After some time I’ve moved into the Information Security field where I feel I found a balance: I enjoy writing security tools and performing technical security assessments. In my free time I like researching security of third party products (both closed and open source).
Open source projects I am or was actively involved:
Security Code Scan - Security static code analysis for C# and VB.NET.
