Platform Architecture & Stabilisation

I take fragile, business-critical platforms and make them dependable, then design the architecture they need to grow.

• Stabilised cloud infrastructure that enabled a successful acquisition
• Architected core features for SaaS compliance and education products
• Brought native iOS and Android apps to market through the App Store and Google Play
• Brought in Git, CI/CD and modern release processes
• Restructured databases and service estates for scale

Systems Integration

I connect products, CRMs and data sources so that information flows on its own instead of being re-keyed by hand.

• Developed an integrated Sales API linking the CRM to the product
• Built automated customer onboarding processes
• Integrated a school communications platform with a school MIS in 72 hours
• Built HubSpot and Salesforce integrations, including data aggregation and analytics

Cloud & Physical Infrastructure

Hands-on across the full stack, from racks in our own data centre to managed cloud services.

• Ran an in-house physical data centre and VMware clusters
• Migrated estates into AWS and moved payment platforms to Azure
• Hyper-V, VMware, Cloudflare, DNS and networking
• Disaster recovery, telephony and 24/7 on-call operations

Leadership, M&A & Delivery

I have led several teams through mergers, acquisitions, migrations and hard deadlines, and I have owned the budgets behind them.

• Managed multi-million pound technical budgets
• Delivered multiple M&A projects and technical due diligence, both as acquirer and as the company being acquired
• Led high-performing engineering and IT teams for 10+ years
• Delivered time-critical projects, including a 72-hour MIS integration
• Trained non-technical staff to become IT engineers

AI Adoption

I champion AI and know where it adds real value and where it does not. I focus on practical results, not hype.

• Identified and delivered AI integrations that made the business more efficient
• Built AI features into products to improve the user experience
• Assess where AI fits best: automation, support, data and development workflows
• Balance AI adoption with security, GDPR and compliance

Security First

Security is central to how I work. I build it into platforms, infrastructure and processes from day one, in sectors where data protection is non-negotiable.

• ISO 27001, GDPR, CIS and PCI DSS
• GDPR Foundation trained
• Led a PCI DSS compliance upgrade across payment systems
• Set up company-wide IT security processes and training

Turned around unstable platforms

• Stabilised a SaaS platform and its cloud infrastructure, which made a successful acquisition possible
• Introduced Git, CI/CD and a proper release process where there was none
• Led code standards that kept critical bugs out of production

Connected systems end to end

• Developed an integrated Sales API and automated onboarding, linking sales, CRM and product
• Integrated a communications platform with a school MIS in 72 hours
• Built HubSpot and Salesforce integrations, data aggregation, analytics and AI features

Ran infrastructure from rack to cloud

• Managed a physical data centre and VMware clusters alongside AWS and Azure
• Led migrations into the data centre, out to AWS, and payment platforms to Azure
• Improved disaster recovery, telephony, ticketing and asset tracking, while on the 24/7 on-call rota

Led teams, budgets and M&A

• Managed multi-million pound technical budgets
• Delivered multiple M&A projects and technical due diligence from both sides, including a three-way merger
• Led teams for 10+ years and trained non-technical staff to become IT engineers
• Delivered time-critical projects, including moving a 100+ person company to remote working within 4 hours

Put security first

• Led a PCI DSS compliance upgrade across payment systems
• Introduced company-wide security processes and staff security training
• Ran infrastructure and development practices in line with ISO 27001, GDPR and CIS

Saved money and grew revenue

• Created and managed a project that saved £350,000 in licensing costs
• Cut AWS spend by £1,500/month with a serverless rework
• Raised monthly completed sales by more than 70 through CRM optimisation

Architecture reviews & roadmaps

An independent look at your platform today, a practical plan to stabilise it, and a long-term technology roadmap based on what is coming next.

Cloud & infrastructure

AWS, Azure and on-prem strategy, migration planning, disaster recovery and cutting cloud spend.

Systems integration

Connecting your CRM, product and data, including HubSpot, Salesforce, APIs and automated onboarding.

Security & compliance

Security reviews of your platform and infrastructure, plus readiness for ISO 27001, GDPR, CIS and PCI DSS, with processes that fit how your team works.

M&A technical due diligence

I have run technical due diligence on both the buying and the selling side, so I can help you assess a target or prepare your own technology for scrutiny.

Engineering process & leadership

Git, CI/CD and release processes, team structure, and interim technical leadership when you need it.

Professional Race Simulators

I designed and built professional-grade race simulators for clients, specified, built and integrated to order. One was built to a European race team specification and sold to a professional team.

• Bespoke builds to each client specification
• Full rig build, wiring, electronics and software integration
• A European-spec build sold to a professional race team

Arduino Plug-ins & Hardware

Custom Arduino plug-ins and wiring projects. Most started as motorsport and sim-racing ideas and ended as working hardware.

• Custom firmware and plug-ins
• Hardware wiring and prototyping
