KPMG managed services operated as an external platform provider - ISVs in fraud detection, risk analytics, and compliance tooling partnered with KPMG to run their software as a managed service for banks, financial regulators, and government institutions, with KPMG owning the full platform and operational layer. I owned end-to-end delivery of the platform layer for multiple ISVs - from initial architecture to handoff.

• Built managed deployment platforms per engagement: custom Kubernetes controllers and helm charts, resource governance, multi-tenant isolation, and security policy across client environments
• Designed platforms with least-privilege defaults, audit logging, and compliance controls satisfying FCA and SEC-adjacent requirements without bespoke work per client engagement
• Built customer-facing portals and API surface through which clients monitored deployments, and used the services
• Designed SLO/error budget framework across managed services - providing clients with contractually-backed service commitments and a structured mechanism for reliability trade-offs
• Built observability stack (Prometheus, Grafana, Loki) and incident response automation that classified failure patterns and triggered remediation runbooks - reducing MTTR on recurring failure modes

• Architected high-availability infrastructure achieving 99.9% uptime
• Reduced system latency by 40% through architecture optimisation
• Designed and implemented zero-data-loss disaster recovery systems
• Implemented automated scaling and failover mechanisms

• Built GPU training infrastructure including a job scheduler balancing cluster utilisation against wait time without starving long-running jobs
• Implemented checkpointing for training pipelines enabling mid-run recovery from failure, reducing wasted compute on long-running workloads
• Built CI/CD pipelines with progressive rollouts, metric-gated promotion, and automatic rollback on regression
• Built distributed tracing and monitoring for debugging multi-service distributed workflows
