Personal portfolio

Hi, I'm Rumesh. I design calm, reliable cloud systems.

DevOps and platform engineer focused on AWS, automation, and observability. I build clean pipelines, resilient infrastructure, and dashboards teams trust.

20+ years across fintech, education, and SaaS. I care about stability, clarity, and shaping systems that are easy to run.

See my work Say hello

Focus

Platform + DevOps

Based in

Stockholm

Currently

Open to collabs

What I build

Glass-clear platforms.

01

Infrastructure foundations

Multi-account AWS, security guardrails, and IaC that scales without drama.

02

Delivery pipelines

CI/CD, GitOps, and automation that keep releases steady and predictable.

03

Observability + cost

Signals that matter, dashboards that reduce noise, spend that stays in range.

Always up for thoughtful engineering chats.
