Sheffield, UK (remote)

Also available: technical leadership CV.

I'm a pragmatic, hands-on leader with a focus on people, shared goals, figuring out what's most important, and making space to achieve it. My background spans operations, engineering and security, which makes a hands-on Chief Information Security Officer (CISO) role exciting.

My experience running JavaScript, Ruby and remote hack events and working with executive leadership in local authorities means I'm well placed to work with everyone from board level to end user, meeting them where they are to foster a collaborative, positive security posture. My time in central and local government has given me a good understanding of vast and aging technology stacks, and experience wrangling them to keep risk acceptable.

I'm an advocate of modern DevSecOps, empowering teams and risk owners to quantify risk and manage it effectively against other priorities, using established frameworks such as the NCSC Cyber Assessment Framework (CAF) and the CIS AWS Cloud Benchmark.

Experience

ISO/IEC 27001 Lead Implementer & Cyber Security Lead

Goodbase Digital Ltd · contract · Remote

Mar 2026 – present

Goodbase build bespoke case management tooling for charities and local authorities. I was brought in to mature their seucrity posture, introduce an Information Security Management System (ISMS) aligned to ISO/IEC 27001, and to lead the infrastructure changes needed to meet the new standards.

  • Shipped the first phase of an ISO/IEC 27001-aligned ISMS, including formal risk management.
  • Introduced infrastructure as code (IaC), retrofitting it across operational systems and adopting it as the default for new deployments.
  • Hardened Google Workspace, AWS, GitHub and Slack against the new ISMS controls.
  • Improved Goodbase's GDPR and data privacy posture through contractual improvements and internal review.
  • Led cyber and information governance responses for sales conversations with prospective clients, including central government bodies.

Interim Head of Cyber Security

London Borough of Hackney · contract · Remote

Apr 2025 – Oct 2025

Role expansion when Hackney's Head of Engineering left and the Council's security function scaled up ahead of a large external audit.

  • Introduced a structured NCSC Cyber Assessment Framework (CAF) to quantify security risk and prioritise improvements.
  • Devised and implemented a 5-year cyber strategy to mature cyber security and risk management within the Council's financial constraints.
  • Led a team of 4 early-career cyber security analysts, providing structured training, mentoring and line management.
  • Introduced Dependabot to quantify software dependency vulnerability risk and auto-update dependencies, training developers and tracking progress through governance sessions.
  • Discovered risk around unmanaged devices, and led work to manage personal device risk and roll out corporate devices for critical systems.

Lead Security Engineer & Technical Architect

London Borough of Hackney · contract · Remote

May 2023 – Apr 2025

Brought in to assess and improve Hackney's security posture for modern engineering projects. Worked closely with engineers and senior stakeholders to identify opportunities for change, getting buy-in from the wider business and enthusiasm from teams.

  • Led an initiative to map Hackney's attack surface and existing systems after discovering ICT wasn't aware of all the services it operated, with many small systems being built by agencies, deployed within AWS, and forgotten. Brokered agreement about ownership and maintenance with the engineering and cloud platform teams.
  • Introduced disaster recovery testing after discovering a lack of backups and testing across the estate. Raised awareness with senior leadership to agree priorities and introduced a way to assess system criticality which was adopted into the wider Council's business impact analysis processes. Tackled slow team response by creating lightweight templates and a runbook, and running in-person sessions covering theory and mob-recovery on problem systems. The work led to improvements in the central backup platform and processes, as well as upgrades to out-of-date systems to enable recovery.
  • Revived Hackney's engineering community of practice. Heavy apprentice/early-career representation and high turnover had left the Slack and CoP languishing. Led by example with talks on security and engineering practices, workshops to build skills, and lightweight decision records as a way to foster discussion. The shift was away from informal decision making to a more collaborative, consensus-driven model — and most engineers became comfortable asking for help.
  • Mentored junior security engineers, introducing learning sessions and pairing/swarming. The team began writing Python scripts to automate laborious manual checks.
  • Ran Community of Practice sessions and workshops with engineers to embed threat modelling, OWASP Top 10, and dependency security.
