Position

Registries. Censuses. Metering.

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

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.
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.
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.
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.
