Project history
Infrastructure, cost and security work for a regulated fintech startup running on AWS (ECS).
- Cut the main production AWS account from $2,000 to $1,370 per month (-31%) in three months
- Cut staging costs by ~$400/month (-40%) by right-sizing and removing unused environments
- Moved part of the workloads to Spot instances, saving ~$220/month
- Hardened AWS security: removed stale accounts and legacy resources from the organisation
- Built an internal status page to track uptime across all applications
- Delivered an expedited demo environment for an enterprise banking prospect
- Stack: AWS (ECS, EC2, Spot, IAM, Organizations), Terraform, Datadog, CI/CD
Formed part of the Platform leadership team, architecting and coding core provisioning services using Pulumi to automate the lifecycle management of 100,000+ workloads across 100+ Kubernetes clusters. Operated high-scale distributed vector database instances managing 30TiB+ of memory. Integrated end-to-end observability architectures and mentored mid-level engineers into advanced technical leadership roles.
Scaled and maintained the Temporal service supporting 50+ engineering teams processing 300M+ concurrent workflows per month. Formulated platform SLOs and advanced monitoring, organized Gamedays for resilience culture, implemented onboarding tooling enabling 10x platform growth in 12 months, and contributed to the open-source Temporal project.
