Products & Services
I build and ship my own software, and offer a small set of productized services. The products have real users; the services come with fixed scope and fixed pricing. Both pay the bills — and keep me sharp.
Products
Apps to use.
ChordFrog
Ear training for musicians
An iOS app that helps musicians develop their ability to identify chords by ear. Multiple practice modes, progressive difficulty, and optional MIDI keyboard support. Built for the daily practice habit.

Self-awareness, visualised
An emotion tracking app that helps you name what you feel with nuance — 82 emotions, three input modes, and eight visual themes. Build a beautiful map of your emotional life, private by design.
getlindenapp.com →StrollCraft
Scenic walking loops, built in seconds
Pick a duration, share your location, and StrollCraft draws a sightseeing route through monuments, viewpoints, and public art — then hands you off to Google Maps to start walking. No accounts, no tracking, no ads. Available in 25 European cities.

Two things, one choice. No friction, no filler.
Pairwise music ranking. Two songs at a time, you pick one — duels add up to a top 10 you didn't know you had. Free without sign-in, capped at 10,000 seats. Live leagues include Taylor Swift, ABBA, and Strolls of Europe sponsored by StrollCraft.
either.fm →CardCard
Digital calling card with a Wallet pass
A permanent contact link plus an Apple Wallet pass for fast, credible introductions — a professional handle anchored to a real identity, not another social profile.
cardcard.me →Numlore
Numbers to words. Words to numbers.
A bidirectional dictionary that maps numbers to words and back — cultural references, Major System mnemonics, T9 keypad letters, leet readings. Built for memorisation, trivia hunting, and Major System learners. Aggregate analytics only; no individual choices recorded.

Productized engagements with fixed scope.
nano-cto
A real human in your pocket
A slice of a senior engineer dropped into a founder's or small team's coding journey. Fractional engagement, sized to fit — for when you need engineering judgment more often than a full hire but more often than a one-off review.
nano-cto.com →lastupdate.site
Get off WordPress. Pay once.
A productized migration off aging WordPress, Drupal, and similar CMSes. One-time fee, static output, no monthly hosting, no renewal — the site keeps running without the maintenance treadmill.
lastupdate.site →nanshe.studio
iOS to Android. Android to iOS.
Cross-platform app porting on a fixed 14-day timeline and flat fee. Native translation, store metadata, and submission included; then a clean handoff to your repo and developer accounts. Optional monthly upkeep keeps the ported build alive in stores.
nanshe.studio →Kebehut
Keep React and Next.js apps alive
Monthly maintenance for React and Next.js apps in production. Fixed pricing replaces yearly spikes and emergency rescues; each engagement also produces a written specification so the next rebuild can be scoped from evidence rather than memory. Currently in pilot.
