Fourteen years between gym floors and online coaching — teaching people how discipline actually compounds. Turned out building software works the same way. Started writing code in 2017 — and if an idea surfaces, it tends to get built.
Building Qodin Studio · Folio A unified ecosystem of synced builds Qodin is a studio architecture binding independent products under one identity layer — shared SSO, linked protocols, and a common design substrate. Each build can stand alone, yet together they speak the same language. ✦ Qodin SSO — one identity across every synced protocol. ✦ Linked Protocols — Glaze, Cess & Facet wired to the same spine. ✦ Standalone Folios — Bookaboo & Milo, independent but of the same hand. Open the Build Registry → — a small studio of interconnected products that share one identity layer. Fewer logins, one design language, products that speak to each other.
Solar-aware React widgets that follow the real position of the sun. Computes the sun's elevation from location and time, then transitions the UI through 9 phases — dawn through midnight — with 10 skins, optional live weather, and animated blends.

Lunar-aware React widgets that follow the real phase of the moon. Computes phase, illumination, and arc position from location and time, then moves the UI through 8 lunar phases with arc-tracking orbs and 10 designed skins.

Transforming source code into high-fidelity marketing artifacts. The design bottleneck, cut out entirely.
Breaking down tax complexity into clear obligations. Automated tracking, threshold monitoring, and filing-ready reports — so you can focus on growing your business, not managing spreadsheets.
A third protocol binding to the Qodin spine. Architecture is set — announcement follows the first two builds.
Every child's bookshelf has the same fifteen books. Bookaboo fixes that. Type in a name, a few favourite things, and the platform writes and illustrates a story that belongs to that child specifically — one nobody else will ever read.
After 14 years coaching people in and out of gyms, one thing became clear — most people don't need a harder programme, they need a smarter one. Milo is that system: an AI companion that adapts to who you actually are, not who the plan assumes you are.
No-code platforms loaded — Groove & Webflow. Freelance tech support. First interface between human intent and digital output.
Core language layer installed — React, JavaScript, TypeScript. First steps into writing real code.
Framework library expanded — Svelte, Next.js, SolidJS. Testing emerging runtimes and component models.
Server-first paradigm adopted — Deno runtime, Fresh framework. Zero-JS-by-default exploration.
Modern framework evaluation cycle. Database migration path — Pocketbase, SurrealDB, Gel Data, Convex explored.
Full-stack architecture engaged — Blade.im & TanStack Start for web. LynxJS for native mobile. Hive by Ronin for storage. Bun & Deno dual-runtime.
Building the Qodin Studio ecosystem — unified SSO, linked protocols, and standalone builds in active development.
Transitioned to Kamal + Docker on Hetzner for full-stack orchestration. Cloudflare edge routing.
If you're stuck on something — a bug that shouldn't exist, an architecture decision that keeps cycling, code that works but feels wrong — reach out. I've been that person staring at a problem for three hours. Sometimes a second pair of eyes is all it takes.
Still active in fitness — not coaching directly anymore, but if you're in Denmark and looking for the right personal trainer or online coach, reach out. Finding a good fit matters more than most people realise, and after fourteen years in the field I know the landscape well enough to point you somewhere worthwhile.
