Karl Kadalipp

Senior Full-Stack Software Engineer

Available for select work

If you live here,
you have used it.

Ten years building the software people rely on without thinking about it — Estonia's vehicle and driver registry, the 2021 national census platform, nationwide energy metering, cross-government data exchange.

Position

Registries. Censuses. Metering. Connectivity.

Systems that carry real consequence when they fail — and are judged on the decade after launch, not the demo. That is the work, and it is the reason the boring parts get the attention.

What I do

  1. Backend that stays correct

    Spring Boot services, Hibernate/JPA data layers and the Oracle & PostgreSQL schemas beneath them — designed to hold up under load and over years, not just demos.

  2. End-to-end, no handoff

    Angular and React front-ends wired straight to the APIs I write, so a feature ships whole rather than being thrown over a wall halfway through.

  3. Government-grade integration

    X-Road data exchange, SOAP and REST service contracts, and the security and audit trails that public-sector systems are held to.

  4. Releases that stay boring

    Docker and Kubernetes deployments, CI/CD, and the testing and code-quality gates — JUnit, SonarQube, static analysis — that keep shipping uneventful.

Enquiries

Have something serious to build?

If it has to be correct, has to talk to systems older than itself, and has to still be running in ten years — that is the work I take on.
