Hi,
I am a kernel developer specialized in security products. Most of the time I am working for antivirus companies. I made many similar projects like freelancer, like you could check in my work history (In google you could look for OctoAntivirus, a project made to a german company). Looking in my work history probably will surprise you and will open many doors to future projects as soon as you check my work line.
Regards,
SysSoftw
