Cloud infrastructure and platforms, engineered to be boring — in the best way.

K. Väyrynen Ltd is an independent consultancy that helps engineering teams design, build, and operate reliable systems on Amazon Web Services. We work hands-on across architecture, automation, and application development — so your platform stays predictable, secure, and cost-efficient as you grow.

Services

Senior, hands-on help across the cloud lifecycle

Engagements are scoped to your needs — from a focused architecture review to embedded, ongoing delivery alongside your own engineers.

AWS Cloud Consulting

Architecture and migration for AWS. We design landing zones, multi-account structures, and networking that scale, then run Well-Architected reviews to find risk and waste before it reaches production.

  • Solution & landing-zone architecture
  • Migration and modernisation planning
  • Security, IAM & account governance
  • Cost analysis & optimisation

DevOps & Platform Engineering

We build the paved road your teams deploy on: infrastructure as code, automated pipelines, and self-service internal platforms that make the right thing the easy thing.

  • Terraform & AWS CDK
  • CI/CD pipelines & GitOps
  • Kubernetes (EKS) & ECS
  • Observability & incident readiness

Application Development

Cloud-native application delivery, end to end. We build backends, APIs, and serverless workloads that fit the platform they run on and are straightforward to operate.

  • APIs & backend services
  • Serverless (Lambda, API Gateway, EventBridge)
  • Data & integration workflows
  • Automated testing & delivery

Approach

How we work

01

Understand first

We start with your goals, constraints, and existing systems — not a template. Good architecture is contextual.

02

Automate everything

Infrastructure and delivery live in code and pipelines. Reproducible environments beat heroics and tribal knowledge.

03

Design for operations

Security, observability, and cost are built in from the start, so systems stay calm and affordable in production.

04

Leave you stronger

We work alongside your team and hand over documented, maintainable systems. No lock-in to us.

About

An independent consultancy built on senior engineering

K. Väyrynen Ltd is a Finland-based consultancy founded by Kimmo Väyrynen. We partner with startups and established engineering teams across Europe that want experienced, hands-on help with their cloud infrastructure and platforms — without the overhead of a large agency.

Our focus is deliberately narrow: Amazon Web Services, DevOps and platform engineering, and the application development that ties it together. That focus is what lets us move quickly and get the details right.
