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.
Focus
Platform + DevOps
Based in
Stockholm
Currently
Open to collabs
What I build
Glass-clear platforms.
Infrastructure foundations
Multi-account AWS, security guardrails, and IaC that scales without drama.
Delivery pipelines
CI/CD, GitOps, and automation that keep releases steady and predictable.
Observability + cost
Signals that matter, dashboards that reduce noise, spend that stays in range.
Selected work
Portfolio highlights.
Multi-account AWS Landing Zone
Built a governed multi-account baseline with Control Tower and SSO, cutting provisioning time by 40% and standardizing guardrails for 20+ teams.
GitLab CI for regulated fintech
Designed multi-tenant CI/CD with dynamic environments and shift-left security, improving lead time to production by 45% while meeting audit controls.
Event streaming observability
Launched a Kafka-to-OpenSearch pipeline with Prometheus/Grafana, reducing alert noise by 60% and bringing MTTR under 15 minutes.
Serverless cost & reliability uplift
Re-architected a Lambda + API Gateway stack with async patterns and canary deploys, cutting costs by 32% and eliminating cold start incidents.
Toolbox
Skills I use every week.

Availability
Useful ways to work together.
I am most useful when a team needs practical help turning cloud complexity into systems they can ship and operate with confidence.
Platform review
Architecture and reliability checks
A focused review of AWS foundations, deployment flow, observability, cost signals, and operational risk.
Delivery systems
CI/CD and GitOps buildouts
Secure pipelines, reusable templates, promotion workflows, and release guardrails for product teams.
Cloud foundations
AWS landing zones and automation
Account structure, identity, network baselines, IaC modules, and controls teams can safely self-serve.
Get in touch
Want to build something steady?
I collaborate with product teams and fellow engineers on cloud foundations, CI/CD pipelines, and observability systems. Happy to chat about your next build.
What I can help with
Architecture and reliability checkups, cost audits, and platform clarity sessions.
Landing zones, GitOps pipelines, and monitoring stacks that ship safely.
Playbooks, runbooks, and training so teams can operate confidently after handover.
