BUILDINGTHINGSTHATMATTER.

I'm Kristoffer — a developer and founder pushing the limits of what software can do. From AI-driven lighting ecosystems to embedded systems and PCB design. Started coding at 13. Haven't stopped since.

Who I Am

FROM PLUGINS
TO PRODUCTS.

Started building Minecraft plugins in Java at 13 — learned everything the hard way through trial, error, and too many Stack Overflow tabs. Now I build real products that run in real venues.

My flagship is Y-Link: an AI-driven DMX lighting ecosystem that turns music into professional light shows in real time. Beat detection, scene evaluation, moving head choreography — all autonomous.

Alongside that I do IT and hardware work at Axentra, and I'm deepening expertise in embedded firmware, PCB design, and ML systems. Currently preparing for a 5-year university program in maths, algorithms, and physics.

“Strong in Rust & JavaScript. Expanding into embedded, AI/ML, and beyond.”

WHAT I'VE
BUILT.

01
RustAI / MLDMXESP32-S3PCBEmbedded

Y-Link

AI-driven DMX lighting ecosystem for the AV and entertainment market. Autonomously generates professional light shows in real time — beat detection, scene selection, moving head choreography. Powered by ALPINE, a deterministic Rust execution engine with real-time beat analysis via CMSIS-DSP and a custom ESP32-S3 PCB with MAX3485 line driver. Priced at 5,000 NOK vs competitors at ~12,000 NOK.

02
TauriNext.jsThree.jsTypeScript

Y-Link Studio

Desktop control application for Y-Link. 3D fixture placement editor, 2D fixture painter, real-time DMX patch grid, AI Show Conductor interface, and Music-To-Motion track resolution via SMTC/MPRIS and MusicBrainz.

03
Next.jsNestJsTypeScriptStripeMariaDB

Flittig UB

Full-stack marketplace app built for a Norwegian youth enterprise (ungdomsbedrift). Adults post local jobs — lawn mowing, house painting, odd tasks — and youth users claim and complete them. Integrated Stripe for in-app payments. Built solo end-to-end.

THINGS I
WRITE ABOUT.

Vibecoding, AI, and the Difference Between Shipping and Understanding

Vibecoding started as an honest term for shipping fast with AI. It has since become a broader identity. The real question is not whether AI writes code, but whether you still understand what you are building.

My First PCB: Lessons from the Y1-Proto-Rev_A

What I learned designing and manufacturing a custom ESP32-S3 + MAX3485 DMX controller board through JLCPCB — from KiCad footprints to a working prototype unit.

Why I Chose Tauri Over Electron for Y-Link Studio

Memory footprint, startup time, and the Rust backend story. A practical comparison after actually shipping both approaches.
