About Me

Full-stack developer and solution architect with 7+ years building and operating a production weighing-cloud platform. I work across the stack — TypeScript and Angular on the frontend, Node.js with NestJS and PostgreSQL on the backend, and AWS with Kubernetes for delivery. Comfortable owning features end-to-end: writing RFCs, leading scope, shipping, and operating what I ship.

Work Experience

Software Developer & Solution Architect - Tamtron Precision Oy - mScales (2019 - Present)

mScales is a production weighing cloud-service. Part of the core development team, growing into a solution architect role across frontend, backend, and infrastructure.

  • Lead end-to-end features across TypeScript/Angular, Node.js/NestJS, and PostgreSQL — from RFC to scope to production rollout
  • Drive architecture decisions: authored RFCs and scope plans for service extraction, deployment redesigns, and feature rollouts
  • Operate the production stack on AWS (EKS, S3, CloudFront, SQS, DynamoDB, IoT Core/MQTT) with Helm, Terraform, and Cloudflare
  • Diagnose and fix production reliability issues (memory pressure, OOM crashes, CI flakiness) using Datadog and targeted refactors
  • Build IoT-edge integrations for industrial scales, including legal-compliance features for the German market

Self Employed - Freelancer (2017 - 2019)

I had been setting up websites for myself and friends.

  • Website development
  • Custom pages
  • E-commerce shop development
  • Wordpress themes

What I Do

Full-stack feature delivery

End-to-end ownership of multi-week features: discovery, RFC authoring, scope planning, implementation across a TypeScript/Angular frontend and a Node.js/NestJS + PostgreSQL backend, feature-flagged rollout, and production operation.


Cloud infrastructure & deployment

Designing and operating production stacks on AWS (EKS, S3, CloudFront, ALB, SQS, DynamoDB) with Helm, Terraform, and Cloudflare. Comfortable owning the path from local dev to production rollout.


Production reliability & observability

Diagnosing and fixing reliability issues in Node.js services on Kubernetes — memory pressure, OOMs, resource limits, flaky CI — using Datadog for observability and targeted refactors to remove root causes.


IoT & edge integrations

Building integrations between cloud services and physical industrial devices over MQTT and AWS IoT Core, including legal-compliance features for regulated markets.
