Backend engineer at Rebtel — .NET, federated GraphQL and Kubernetes — and lately, rethinking how engineering teams work with AI.

I'm a backend engineer with five years in .NET, based in Stockholm since 2024. At Rebtel I work on the platform behind international calling, mobile top-ups and money transfer — a system serving millions of users, running as a fleet of microservices on Kubernetes. I like owning things end to end: design, code, pipelines, deployment, and the on-call phone. And I care about how teams build — lately, that means defining how AI fits into the everyday engineering workflow.
When Rebtel needed to replace its legacy accounting system, I designed and built the successor: a double-entry ledger service that now handles every charge, reservation, refund and VAT calculation on the platform. Then came the harder part — migrating a decade of accounting behaviour onto it, service by service, without breaking the money.
I founded and drive the cross-team AI engineering initiative at Rebtel. The centrepiece is a skills platform for Claude Code — thirty-plus skills that encode our architecture patterns and development workflows, with telemetry to see what actually helps. The goal isn't autocomplete: it's making agent-driven development shared, reviewable and consistent, from ticket intake to opened pull request.
Rebtel's client APIs run on federated GraphQL — a HotChocolate Fusion gateway composing domain subgraphs. I drove key parts of that architecture: the implementation-first type system, real-time subscriptions over Redis, and the cross-service rewrite that standardized how the platform's services expose their schemas.
The French state publishes a remarkable amount about who it appoints — nobody had joined it up. Le Cercle turns four million Journal officiel appointments and a dozen open datasets into an explorable map of who staffs the top of the French state, and who they are tied to.
A free SpeedCoach for Android, made for my rowing club: stroke rate, split and distance from the phone's GPS and accelerometer, pieces and workouts, a heart-rate strap, and a Concept2 PM5 over Bluetooth for erg sessions and races. No account, no ads, GPL-3.0.
I run with this crew, so I rebuilt their site: plain HTML, no framework, no build step — with a live countdown to the next run, calendar invites that survive daylight saving, and a weather forecast drawn in hand-made SVG icons.
I row competitively, and from 2024 to 2026 I served on the board of Akademiska Roddföreningen in Stockholm — responsible for the club's boats and equipment, and stepping in as interim coach for the competitive team. Rowing at six in the morning teaches you things standups can't.
Swedish winters converted me: long-distance skating on natural ice, cross-country skiing when the snow is right, alpine when it isn't. The season the water freezes is the season I look forward to most.
I travel slow when I can — long trips with a backpack rather than a checklist. It started with an Erasmus winter in Linköping that eventually turned into a life in Sweden.
