Curriculum Vitae / Resume

Adrian ColegateProfile

I am an adaptable and pragmatic IT professional with broad and deep technical skills. I draw from my experience which began with 6502 assembly and moved to 4GLs, networking, operations through to full-stack internet application development, cyber security, leadership and everything in between.

My mantra is “Simple above Easy” and the systems I’ve built reflect my values. They are robust, modular and most importantly: maintainable. I gain personal satisfaction from designing and building solutions from their inception to their final delivery and beyond.

I am a skilled software, systems and security engineer, architect, technical evangelist and effective communicator at all levels.

My skills cover the full technology stack and include

  • UI and UX design
  • Workflows and threat modelling
  • Data and architectural design, optimisation and security
  • Business layers and services
  • Application security, design, build and test
  • Penetration testing
  • Solution delivery
  • Solution support and maintenance

Employment History

Senior Software Security Engineer at Just Eat. Farringdon, London.

Just Eat has over 24 million active customers across 13 countries worldwide and over 80,000 restaurant partners in the UK alone.

I was brought into a new InfoSec team based on my development and hands-on security skills. As a member of our Security Team, it’s our responsibility to ensure our Customer and Restaurant Partner data along with our infrastructure and IP is always protected and securely handled.

I’m involved with education, security workshops and presentations and provide provide architectural and data handling direction to project teams. I also run threat modelling sessions and work with our engineers to resolve code vulnerabilities. I run our vendor and product security reviews and help with our PCI compliance and regular penetration testing.

I’m subject-matter-expert on our edge protection and took ownership of our DDoS mitigation and CDN WAF to maximise use of the service. I have good technical relationships with our security vendors and actively contribute to their service road-maps. I started Just Eat’s “Shifting Security to the Left” initiative and rolled-out Static Application Security Testing (SAST), Software Composition Analysis (SCA) and Package Firewall to our CI/CD pipeline.

I’ve brought the concept of Agile to InfoSec. I acted as Agile Coach and Scrum Master and used my many years of Agile working to educate, reassure and guide all InfoSec team members. I’ve written documentation explaining Agile and how we will adopt it, ran ceremonies and maintained strict order. I capture retrospectives and coordinate backlog refinement and sprint planning. We are now Agile and have whole-team buy-in.

I’m involved in the OWASP London Chapter, contribute to security forums, attend conferences and collaborate with external security teams to share knowledge and experience.

I understand and empathise with engineers help them understand the value of security. I also appreciate the values of senior managers and our exec and their need for perceived value. I work at all these levels with passion, authority and the pragmatism that years of varied hands-on experience provides.
