Enthusiasm for technology & cybersecurity and passion for creativity

or a passion for creativity

That's probably the shortest definition of me. :-]
Or perhaps my approach is best expressed by my long-standing philosophy, born out of experience:

one way to show respect for people in everyday life is a well done job

use ip_spoofing::{self, RawSocket, ReusablePacketWriter};

fn main() -> ip_spoofing::Result<()> {
    let socket = RawSocket::new()?;
    let mut writer = ReusablePacketWriter::new();

    socket.send_fake_udp_packet(
        &mut writer,
        [8, 8, 8, 8],
        1234,
        [127, 0, 0, 1],
        5678,
        b"hey",
        64,
    )?;

    Ok(())
}

Cyber Security/Cyber Defence

Be safe even from NSA

I have been working in the field of cyber-security & cyber-defence since 2010, when I entered this field with my first clients and expanded my scope to include services in this area. Over time, the portfolio has grown and I am now able to offer a wide range of cyber security/defence services.

  • Risk analysis
  • Penetration testing
  • Crisis scenarios
  • Infrastructure architecture

Software Development

Make your ideas real

I've been developing software for 19 years now, and in that time I've created and delivered many diverse applications for desktop, web and mobile. And have been partly involved in many others.

I've been part of some interesting government contracts. Collaborated on security architecture design for companies like Proton AG (protonmail). And experienced working in a war zone, in extreme conditions and under pressure, where a mistake can cause not only the application to crash, but in the worst case the loss of human life.

private unsafe double CalculateSum(int count)
{
    double sum = 0;
    double* values = stackalloc double[count];
    for (int i = 0; i < count; i++)
    {
        sum += values[i];
    }
    return sum;
}
export const YearsOfExperience = () => {
  const experience = '19 years 5 months'
  return `${experience} of experience.`
}

So I offer all my experience wherever it is needed. Whether you need advice on securing a corporate network or employee communications in a high-risk area, conducting a risk analysis or preparing crisis scenarios, or 'just' develop an application or dream software product, you've come to the right place.

Coz I am your real partner in virtual world.
