Recent Experience
Recent systems I was trusted to own
Work from teams where releases, access, cost, and availability had direct business consequences.
DevOps Engineer
London Stock Exchange Group Finland
2023–2025
Owned cloud infrastructure, reliability, and delivery systems for regulated financial platforms across trading and surveillance domains.
Impact
- Reduced cloud costs by 35% (~$75K/year) by introducing governance models and usage controls across multi-account environments.
- Led migration of regulated workloads from on-prem to cloud, redesigning architecture around isolation, security boundaries, and future growth.
- Introduced controlled failure testing to expose weak points earlier and cut downtime by 20%.
- Owned end-to-end delivery systems (infrastructure + CI/CD), reducing deployment time by 40% and errors by 35%.
- Defined Kubernetes RBAC and network segmentation so multiple teams could share platforms without broad access by default.
