Senior Infrastructure & Systems Engineer
Systems Architecture · Networking · Cybersecurity
I design and build resilient infrastructure, from bare-metal datacenter buildouts and multi-layer network architectures to cloud-native security frameworks and automation tooling. 17+ years of hands-on experience across fintech, quantum computing, and enterprise IT.
About me
I've spent over a decade building and securing the digital infrastructure that businesses depend on. My career spans network engineering, datacenter design, cloud migration, and cybersecurity architecture. I emphasise simplicity, reliability, and automation.
I believe that anyone should be able to manage a well-designed system. Complex topology doesn't signal expertise; an elegant, maintainable infrastructure does.
Currently based in London, I bring deep expertise in both traditional on-premises environments and modern cloud platforms, with a strong focus on security, compliance, and infrastructure-as-code practices.

Work experience
Over 17 years delivering infrastructure solutions across security-critical, high-availability environments.
Quantinuum Ltd
Transitioned into a new role supporting the infrastructure needs of the company. Responsible for the integration of Quantum Computers into customer environments. Supporting migration from legacy systems to new global technology stack.
Quantinuum Ltd
Joined Cambridge Quantum Computing Ltd. (CQCL) as quantum cryptography engineer, then supported the merger with Honeywell Quantum Solutions to form Quantinuum. Promoted to Solutions Architect responsible for designing and integrating cybersecurity solutions for enterprise clients, including post-quantum cryptography implementations, HSM deployments, and cloud security architecture across Azure, AWS, and GCP.
Cashplus Bank (was APS)
Led the technical rebranding of Advanced Payment Solutions to Cashplus across Windows domains, Microsoft 365/Azure, and partner networks. Owned all infrastructure platforms, storage systems, and physical/virtual networking. Championed DevOps practices and automation to support business growth.
Advanced Payment Solutions (APS)
Principal engineer responsible for all technology platforms, third-party relationships, and hosting infrastructure. Led PCI DSS compliance programme and delivered two multi-million pound datacenter buildouts from bare metal — including full-stack deployment of networking, hypervisors, VMs, and databases through to live production rollout.
cloudBuy PLC (was @UK PLC)
Responsible for installing, maintaining and growing the company's infrastructure whilst ensuring PCI DSS Level 1 and ISO 27001 compliance. Performed on-site datacenter work, managed system access for global teams, and authored risk assessment and disaster recovery documentation. Developed automation scripts for backup and recovery systems.
Education & Certifications
Academic grounding in computer science combined with hands-on technical certifications.
Undergraduate Degree
University of Leicester
2009 — 2012
Studied programme design, automata theory, operating systems, networks, distributed systems, algorithms, cryptography, and internet/cyber security.
Professional Certification
VMware (VMWAREICM65)
2017 — 2018
VMware vSphere 6.5: Install, Configure, Manage. Formal certification in enterprise virtualisation platform deployment and administration.
Key achievements
Delivered PCI DSS compliance programmes across two companies, covering both policy architecture and technical implementation of security controls.
Delivered two multi-million pound datacenter projects from physical racking through to full-stack deployment, networking, hypervisors, and live migration.
Led integration of quantum-secure technologies — QRNGs, post-quantum VPNs, and HSMs — into enterprise client infrastructures at Quantinuum.
Publications & Projects
Peer-reviewed research and deployed industry projects at the intersection of quantum security and enterprise infrastructure.
A peer-reviewed paper exploring the vulnerability of blockchain protocols to quantum computing attacks, and proposing post-quantum cryptographic approaches to future-proof distributed networks. Published in Scientific Reports, part of the Nature Portfolio, one of the world's leading multidisciplinary journals.
Named author on the HSBC–Quantinuum whitepaper documenting the first real-world deployment of quantum-secure technology for distributing tokenised physical gold. The project successfully trialled a post-quantum cryptography VPN (PQC VPN) to protect HSBC's distributed ledger technology against future quantum computing threats without requiring re-architecture of existing production DLT infrastructure.
