Enterprise Technology Operations
It fails when dependencies are missed, assumptions go unchallenged and the right conversations happen too late.
That’s where I come in — making enterprise technology change operationally ready, from dependencies to production cutover.
The person behind the questions
Enterprise Technology Operations Manager
I help organisations navigate complex technology change by making dependencies, governance and operational readiness visible before they become delivery risks.
The role complements project delivery: it helps ensure the technology is ready to be delivered.
How I think
Each example began with a different technical challenge. The work was to make the broader operational picture clear early enough for the right people to act.

E2openEmployerEnterprise experience
Experience matters most when it shows how technical, operational and organisational dependencies were handled together.
Migrating more than 80 enterprise applications from colocation into Oracle Cloud Infrastructure.
The objective
Move a SaaS application estate serving more than 3,000 global organisations from Equinix colocation into Oracle Cloud Infrastructure.
The dependencies
More than 80 applications brought infrastructure, networking, database and integration dependencies together, with no scope for extended downtime. Disaster-recovery planning and recovery testing were part of the readiness picture.
The contribution
Worked across infrastructure, networking, database, DevOps and application teams to establish readiness, surface dependencies and challenge assumptions before cutover — contributing to roughly £0.5m in annual operating-cost savings.
A business-critical SAP transition with operational continuity in view from the start.
The objective
Support a business-critical SAP ERP transition while maintaining operational continuity.
The dependencies
Networking, infrastructure, databases and application teams all had to be aligned. VPN readiness, firewall changes, monitoring and end-to-end integration testing were part of the production picture.
My thinking
Validate technical readiness early, bring customer specialists, Solution Architects and multidisciplinary engineering teams into the same conversation, and make assumptions visible before switchover.
The contribution
Facilitated technical workshops across multiple organisations and validated the readiness work needed to reduce implementation risk and strengthen operational readiness.
What it reinforced
Business continuity is not an end-stage check. It is the result of the right technical conversations happening early enough.
Modernising more than 3,000 customer integrations from legacy HTTP and FTP to HTTPS and SFTP.
The objective
Retire unencrypted production exchanges and improve the security of a large customer-integration estate.
The dependencies
Customer firewall rules, source IP validation, connectivity testing and customer change windows all needed to align before legacy services could be withdrawn.
The contribution
Connected network, application and customer engineering teams to validate each migration path, reducing technical debt while keeping disruption to a minimum.
Secure connectivity and production readiness for a new cloud-hosted enterprise platform.
The objective
Establish secure production connectivity between Heineken UK’s head office and a new cloud-hosted enterprise platform.
The dependencies
Customer infrastructure teams, internal networking specialists, VPN implementation, production connectivity and end-to-end data exchange all had to be coordinated.
The contribution
Coordinated readiness and validation activities so monitoring and operational acceptance were complete before service transition, with post-go-live hypercare to safeguard the new connection through its first weekend in production.
Seven years leading 24/7 Priority 1 technical incident response for Tier 1 enterprise platforms worldwide.
The objective
Restore critical services and give enterprise customers clear, technically informed updates while incidents were still unfolding.
The dependencies
Each incident could require the right specialists across infrastructure, networking, databases, applications and development to work as one response team.
The contribution
Led technical investigation under pressure, tested assumptions quickly and brought the right experts into the response to accelerate root-cause identification.
The next conversation
If you value someone who sees dependencies, operational readiness and cross-functional technology alignment early, I’d be glad to talk.
