Background

About me

I'm an Azure Engineer and Security Consultant with a background spanning penetration testing, large-scale cloud automation, and enterprise systems administration. Most recently at In.security Ltd, I was the sole engineer responsible for building and operating Azure-based infrastructure platforms used to deliver hands-on security training at major international security conferences.

My main project is a 12,000+ line Terraform codebase that fully automates the provisioning of per-student Azure lab environments — replacing fixed on-premises infrastructure with a scalable, on-demand architecture that can be deployed globally, at any scale, in minutes.

Prior to that, I spent three years in penetration testing and enterprise systems administration — delivering vulnerability assessments, leading infrastructure migrations to hybrid Azure architectures, and building internal tooling that dramatically reduced operational overhead.

I'm now targeting Azure Engineer and Infrastructure Engineer roles, bringing deep hands-on cloud infrastructure experience with a security-first mindset developed through years of offensive security work.

Security Consultant & Azure Infrastructure Engineer

In.security Ltd

Dual role combining offensive security consulting with sole responsibility for the organisation's entire Azure cloud infrastructure. I design, build, and operate the platforms that deliver hands-on cybersecurity training to professional audiences at some of the world's largest security conferences.

On the infrastructure side, I own everything from Azure tenant and subscription architecture through to per-student lab provisioning, VPN onboarding, and live monitoring during events. On the security side, I deliver penetration testing engagements across infrastructure, applications, and networks for enterprise clients.

  • Designed and built a fully automated Azure training platform defined in 12,000+ lines of Terraform IaC, migrating the organisation from fixed on-premises lab infrastructure to a scalable, on-demand Azure architecture
  • Implemented parameterised Terraform deployments enabling per-student lab environments, eliminating manual provisioning and enabling consistent deployment across varying course sizes and global locations
  • Architected multi-domain Active Directory environments in Azure, enabling realistic enterprise attack scenarios while significantly reducing operational overhead
  • Implemented a secure OpenVPN platform with automated client configuration generation, streamlining onboarding for training participants
  • Deployed and operated a Linux services platform in Azure supporting PostgreSQL, SMTP/Dovecot, GoPhish, and CTFd for training environments and security simulations
  • Successfully delivered Azure-hosted training environments at Black Hat USA, Black Hat Europe, Security Fest (2025), SEC-T (2024), and TROOPERS (2025)
