Site Reliability Engineer · Tampere, Finland

I'm a Site Reliability Engineer from Tampere, Finland. I keep large distributed systems fast, observable and pleasantly boring, so product teams can ship quickly without getting paged at 3 a.m.
Over the past decade I've run on-call for payment platforms and cloud hosting, built SLO programs from scratch, and turned a lot of manual toil into small, well-tested automation.
Reliability is something users feel, not a dashboard colour. I work closely with developers to define what "good" means, measure it honestly, and spend error budgets on purpose.
I write production-grade tooling: operators, CLIs, CI pipelines and the occasional Slack bot — tested, reviewed and documented like any other service.
Replaced 400+ static threshold alerts with multi-window, multi-burn-rate SLO alerts generated from a single YAML spec per service.
Led the move of 120 microservices from self-managed clusters to Amazon EKS with Argo CD, Karpenter and progressive traffic shifting.
Designed a fault-injection programme (zone loss, DNS failure, dependency latency) with scripted scenarios and a scoring rubric for teams.
Rebuilt the observability pipeline around OpenTelemetry Collectors with tail-based sampling and log-level budgets per team.
A small Go service that enriches every alert in Slack with its runbook, recent deploys and a one-click incident channel.
