Backend
Kotlin and Spring Boot in production since 2019, TDD since 2001. Event-driven integrations on Kafka and Azure Service Bus, operated on Kubernetes and OpenShift. New code is verified against what it replaces, in production.

Backend and architecture in Kotlin/Spring Boot, for systems where mistakes are costly.
25 years in the field, the last three at the Norwegian Public Service Pension Fund (SPK). Pensions, banking and insurance, public sector. Close to the domain experts until the rules are right, TDD since 2001, and AI tooling in everyday development work.
Available for a new engagement from January 2027 · Previously security cleared, can be cleared again
25 years solution architect and senior backend developer
Kotlin · Spring Boot in production at SPK, Mestergruppen, Eika and Telenor
Pensions · banking · insurance · public sector systems where the rules are complex
Available from January 2027 independent consultant through my own company
Three areas, one thread
From the domain rules to code in production: backend, architecture and AI.
Architecture
Domain model and solution architecture built together with the domain experts, until the rules live in the code. From monolith to services in step with the team's regular deliveries, no big bang.
Read more →AI
AI tooling in everyday development work, not as a side pilot. Context engineering, agent workflows and my own tooling that keeps sensitive data away from the agent. I write about it on finnrobert.no.
Read more →How I work
A short path from the domain rules to code that runs.
- 01
Understand
Learn the domain together with the experts, until the rules and the edge cases are clear.
- 02
Architect
Design the domain model and service boundaries, and choose a path that tolerates the rules changing.
- 03
Deliver
Build it test-driven in Kotlin/Spring Boot, verify it against what exists, and put it in production.
Selected work
Three engagements that show how I work.
Payments on My Page, Norwegian Public Service Pension Fund (SPK)
A Java monolith that loaded slowly and produced errors because the domain rules were missing from the code. Rewrote the logic in Kotlin/Spring Boot with the settlement experts, and verified it against the old code in production until every discrepancy was explained.
Response time four times faster
New pension calculator, Norwegian Public Service Pension Fund (SPK)
Architect and backend developer for the calculator members use to plan their retirement, and the internal variant for case workers. Kotlin/Spring Boot on Kubernetes, built on SPK's domain services.
First release planned before the end of 2026
Order integration Norway–Sweden, Mestergruppen
Event-driven integrations on Kafka in Kotlin/Spring Boot between the order systems in two countries. Requirements worked out continuously with the business, acceptance tests in Cucumber.
In production 2023

Behind Intello is Finn-Robert Kristensen.
On finnrobert.no I write about AI and context engineering in practice — real setups, no hype. What I explore and share there is the same craft I bring into client work here.

Kontekst som overlever økta
Alt du forklarer i en prompt er borte når økta er over. Det som avgjør om arbeidet kan fortsettes neste uke, er hva som ligger i filer verktøyet leser neste gang: beslutningene, og dokumentasjonen av hva som er bygd og hvorfor.

Context-filen: struktur, språk og rekkefølge
Alle skriver at du bør ha en instruksfil til KI-verktøyet ditt. Få skriver hvordan innholdet faktisk bør se ut. Her er rekkefølgen jeg lander på, hvordan reglene bør formuleres — og hva filen heter i de ulike verktøyene per august 2026.

KI i en norsk bedrift: hvor du faktisk bør begynne
Du trenger ikke en KI-strategi for å komme i gang. Du trenger én kjedelig oppgave, én nysgjerrig person, to uker — og et ærlig svar på om det virket.
