About Me

I have been enthusiastic about computers and networks from a young age. I am experienced in developing software and web applications in a variety of languages, though the languages I reach to the most for various purposes are C++, Python and PHP.

I have a strong interest in sound and music production, spending time refining a particular sound. I concentrate on making psytrance because I enjoy, not just the music, but also the precision in making that music at all stages allowing a deep technical exploration into the sound and flow that makes up the tracks.

Experience

I have spent over four years in penetration testing which gave me a broad view of IT networks, infrastructure and web applications covering councils, public sector, banking, charity, SME, MNC and an airport. During that time I developed custom software based on the process of network testing; integrating industry standard tooling into a broader software framework for testing and striking the balance between manual and automated. This improved the speed of my testing, managing large corporate networks and the huge amount of information coming in from the hosts and services.

The experience of delivery project after project has helped me understand the setup and expectations of varied corporate networks and web applications across different sectors and that Windows is the go-to ecosystem for business of all sizes.

  • Over four years penetration testing experience across diverse sectors (e.g., public sector, banking, charities, SMEs, and airports).
  • Developed custom software integrating industry-standard tools into a broader testing framework.
  • Optimized the balance between manual and automated testing to enhance efficiency.
  • Improved testing speed and scalability for large corporate networks and high volumes of data.
