Solo founder · builder · maker of too many things
I build apps and businesses, write worlds, run games, and learn hard things in 30-day sprints — and I'm looking for talented, curious people to make the next ones with.
What I'm building
A few things I've shipped or am shipping — the small, well-made kind of software, and the engine behind it. ~160 ideas in the notebook; these are the ones that became real.
The fastest honest path to a new language: one expertly-ordered deck, real native audio, and spaced repetition that does the thinking for you. I taught myself Japanese to A1 in about 20 focused hours with the method — then spent a year building the app that strips out every ounce of the friction that makes people quit. The whole thing is built — backend, payments, the scheduling engine — quietly switched off while I finish my own paperwork.
A minimalist weight-and-habit tracker built so the graph does the nagging. My mom lost 17 lbs with it — the first thing that ever worked for her.
A focus tool I built in ~40 lines one night. A YC-backed founder lost it over the thing live on stream; the tweet did 100k+ views. The small, well-made kind of app I like to ship.
A metronome that actually feels good to use. A tool that finds the exact episode where a show finally gets good. More live at kalden.me.
Apps, games, businesses, books — each ranked, named, and MVP-scoped. Grab one off the shelf and build it with me.
The idea engine →The breadth
The work above is just what's current. This is the fuller map — overlapping sides of one stubbornly curious brain. Each has a deep page that says both what I've done and what I'd love to do next. Pull on whichever thread is also yours.
Writing
Distinct from the work — ideas, not portfolio. Finished from years of drafts.
Someday
Through the lens
Portraits, fits, and the cities I've lived in — a month or two at a time. One camera, a single 23mm prime, natural light, graded by hand.
And some things I do purely for myself — painting like no one will ever see it, building and painting Gundam kits, singing in the mornings, the occasional cosplay. No goal. Just the doing.
Let's build something
Collaborators, co-conspirators, friends. If any of these worlds is also yours — or you just want to scheme — say hi. The best things in my life started as a five-hour first conversation with a stranger.
