Building infra
engineers trust.

With over 10 years of hands-on DevOps and SRE experience, I work with European B2B tech companies to build infrastructure that is secure, observable, and built to scale. From zero to production — I design and operate cloud environments, CI/CD pipelines, and Kubernetes platforms that give development teams the speed and confidence they need. Based in Finland, available for consulting engagements across the EU.

Cloud-native, AWS-first Hands-on with AWS services, multi-account architectures, and infrastructure-as-code at scale.
Kubernetes at depth From cluster bootstrap to production-grade multi-cluster operations with GitOps workflows.
Observability & reliability Full-stack monitoring, SLO design, and incident frameworks that reduce MTTR dramatically.
Security-conscious Hardened baselines, least-privilege IAM, secrets management, and compliance-ready environments.

What I do

End-to-end infrastructure and platform engineering, from architecture to day-two operations.

Cloud & Infrastructure

AWS-first infrastructure design, IaC with Terraform & Terragrunt, cost optimisation, multi-account strategies.

CI/CD & Automation

GitLab CI, GitHub Actions, ArgoCD pipelines — from commit to production in minutes, not hours.

Kubernetes & Containers

Cluster design, Helm chart authoring, multi-cluster operations, autoscaling and workload optimisation.

Monitoring & Observability

Prometheus, Grafana, Loki, ELK stack — full-stack observability so you know before your users do.

Security & Resilience

Hardened baselines, secrets management, disaster recovery, SLOs, and on-call runbook design.

Consulting & Support

Architecture reviews, team enablement, incident post-mortems, and ongoing SRE advisory retainers.
