Photo I’m a developer and software architect with more than 25 years of experience in the business. My first computer was the Atari 800XL, where I have collected my first programming skills in the assembler language because all other languages have been unusable for large projects on this platform.

After that I have moved on the PC platform, where I have experience with Windows and Linux system administration and programming.

In the last decade I’m focusing on network security, Windows networking system and Windows Network Drivers development.

In the past I worked for the AVG, well known antivirus company, where I led design and development of the AVG Firewall component.

At present I live in Brno, Czech Republic, where I work for the AVAST Software – company which develop popular AVAST! antivirus solution. Here I’m responsible for the network traffic WFP based driver filtering solution.
