Senior Product & Delivery Manager
June 2025 – Present
Product and Delivery Lead in a crucial cloud transformation programme focused on modernising and enhancing the infrastructure used by vital law enforcement agencies across the UK.
FinOps
Problem
The platform’s cloud spend was accelerating with minimal visibility, an outdated charging model and no clear ownership of financial decisions across teams. This resulted in poor assessment ratings and a pressing need to regain control, stabilise costs, implement effective governance and embed a FinOps-by-Design operating model.
Outcome
Accelerated the FinOps capabilities within the programme by advancing cost control measures, governance and oversight over cloud spend, leading to progressing the programme from a ‘Pre-crawl’ to a ‘Walk’ maturity during assessments, as well as achieving the best-in-class role model rating for AWS Landing Zones in the public sector.
Achieved Platform savings of £100,000 per month, through the adoption of Instance Scheduling, migrating to Graviton Instances, centralising VPC endpoints and migrating logs from Splunk to Security Lake.
Implemented a usage-based recharging model for tenants, ensuring fairer and transparent cost allocation aligned with actual consumption and subsequently reducing programme costs and achieving a cost-neutral platform.
Observability
Problem
Observability across the platform was fragmented. With no unified solution in place, individual teams were building their own bespoke monitoring and alerting setups instead of adopting a shared, scalable approach. Splunk performance resulted in a mean time to triage of 45 minutes, monitoring-as-code practices weren’t understood or adopted, and there was no obsolescence tracking or resilience checks. The team’s overall scope was too limited to provide meaningful end-to-end visibility or governance.
Outcome
Defined a 12-month roadmap to address the platform’s critical observability and monitoring gaps. Consolidated Operational Monitoring and Protective Monitoring into a single, cohesive team to improve scope, governance and visibility. Led the delivery of the modernised Observability roadmap, including a unified Alert Management solution, platform-wide monitoring (Prometheus & Grafana), obsolescence tracking (AWS Health, Trusted Advisor), and clear visibility through QuickSight dashboards and alerts.
Delivered a shared Alert Manager capability that standardised alert ingestion from Prometheus and CloudWatch and routed them into ServiceNow. This replaced the fragmented, team-built solutions that were unreliable, inconsistent and difficult to scale. By moving to a single platform service, teams and tenants could onboard quickly, reduce operational risk and ensure critical alerts were captured and actioned consistently.
Implemented Security Lake to reduce dependency on Splunk, improving data availability and lowering ingestion costs. This reduced Mean Time to Triage (MTTT) from 45 minutes to eight minutes and reduced the Splunk bill by 40%
