Skadi Oy · Helsinki · 2026

What I've been up to lately

Three product surfaces, two consulting tracks, and a lot of walking.

What I do

Three things, on purpose.

  1. Products

    Apps and webapps under the Skadi roof.

    Linden · ChordFrog · StrollCraft · either.fm · CardCard.

  2. Packaged consulting

    Fixed scope. One-time fee. No retainer.

    lastupdate.site · nano-cto · kebehut.com (soon).

  3. Freelance, hourly

    Customer-named work, billed by the hour.

    Quiet. Steady. Boring on purpose.

StrollCraft · strollcraft.app

Stroll around where you already are.

Tell StrollCraft how long you have. It draws a walking loop through nearby sights — monuments, viewpoints, historic buildings, parks, public art — that ends back where you started.

Not a fitness tracker. Not a travel guide. A way to turn idle time into a walk worth taking.

either/fm

I'm a very specific kind of nerd.

I wanted to ELO-rank Taylor Swift's catalog. So I built the thing that does it.

either.fm shows two songs at a time. You pick the one you'd play again. The duels add up to a personal top 10. Currently a closed beta with 1,000 seats.

Two songs. One choice. No follower counts. No algorithm trying to be your friend.

CardCard · cardcard.me

A business card, but it's a link.

One permanent URL. One Apple Wallet pass. Contact details that travel anywhere a phone can scan.

Anchored to a real identity, so the person on the other end of the link isn't a guess.

In flight · two iOS apps

Two iOS apps in flight.

ChordFrog — ear training app screen.

ChordFrog

Train your ear. Master chords.

An ear-training app that grows with the player. MIDI keyboard for real-time chord recognition, or quiz modes anywhere. Five progressive levels — triads up to the full chord vocabulary.
