Chief Technology Officer @ Edition (formerly Ejlskov.design) — Denmark

Engineering leader building custom systems, apps, and integrations for ambitious clients.

I lead engineering at Edition, a Danish digital agency. We have deep roots in Shopify, but just as much of our work is custom — building bespoke apps, internal systems, headless CMS platforms, and the integrations that connect everything in between.

My path here:

• Started out customizing WordPress / PHP for friends, family, and small clients (~2-3 years)
• Joined Edition as a Frontend Developer (2 years)
• Moved into Backend / Full-stack (2 years)
• Stepped into CTO (1 year and counting)

I care about pragmatic architecture, clean DX, and shipping things that don't break at 2 AM.

Edition ‑ Expansion Store Sync — Shopify App Store (launched Jan 2026)

A multi-store product sync app letting merchants manage product, variant, inventory, and pricing data across multiple Shopify stores from a single source — with individual sync rules per connected shop. Built to handle the messy reality of running international expansion stores at scale.

5.0 ★ on the Shopify App Store · Solo developer — architecture, backend, frontend, and Shopify integration end-to-end.

Internal Shopify App Template

Built our internal boilerplate for shipping production-grade Shopify apps fast. Next.js + TanStack on the frontend, Redis + BullMQ for background jobs and scheduling, and an event-driven app bus tying it all together. Typed end-to-end in TypeScript, with built-in webhook handling and retries, structured logging, CI/CD pipelines, and a testing setup ready out of the box.

Built solo. Now the foundation behind every new Shopify app we ship — turning repeated production pain into a one-command starting point and standardizing the team's stack and patterns.

• Custom apps & systems — building bespoke applications when off-the-shelf doesn't cut it, from internal tooling to client-facing platforms
• Integrations — APIs, queues, and the glue that connects business-critical platforms across the stack
• Engineering leadership — building processes, choosing the right stack for the job, and making sure the team can ship without burning out

Full-time at Edition, but always open to sparring, advisory, or lending a hand on interesting problems.
