Hi! I'm Mark

I am an experienced penetration tester with a focus on application security in the following areas:

  • Web applications
  • Mobile applications
  • Desktop applications
  • APIs, SDKs, and Web Services
  • Cloud applications
  • Microservices and containerized applications
  • Serverless applications

Over the years, I have developed extensive experience in orchestrating comprehensive security assessments for a diverse range of applications and cultivated expertise in:

  • Strategic Leadership: Defining methodologies, innovating toolsets, and setting best practices that steer effective and efficient penetration testing.
  • Consulting: Serving as a principal application security consultant specializing in web, mobile (Android & iOS), automotive, desktop, and API testing.
  • Mentorship: Empowering the next generation of security experts through training, guidance, and thought leadership.
  • Collaboration: Bridging gaps between security teams, fostering a collaborative environment to collectively drive application resilience.
  • Remediation: Identifying and developing remediation strategies for security findings and bug bounty reports, collaborating with development teams to ensure effective implementation.
  • Comprehensive Security Assessments: Executing a wide range of penetration tests including external, internal, and application testing for global clients in various sectors, leading projects from scoping to detailed reporting and remediation.

I am passionate about strengthening the security posture of applications, constantly evolving my techniques to stay ahead of emerging threats, and ensuring the highest standards of application security.
