Yanis Schweizer
I build apps, automations and AI tools.
Three main quests. A handful of side quests. One rule: I decide, AI types.
Vaultt
Where young talent gets hired on proof, not a CV. Built from zero with founder Liam Jeffery.
YouCook
Tell it what's in your fridge. Get dinner, a weekly plan and the shopping list.
Side quests.
Client builds, design systems and my own apps. Shipped, shipping or in the forge right now.
Endless Pursuit
A mobile app where ambitious people track their progress with a small circle that holds them accountable.
HandoverOutreach & CRM System
Replaced a spreadsheet outreach process with one app: find leads, email them from real mailboxes and catch every reply.
DeliveredPlayivity
One design system and a cast of animated characters for a kids’ activity platform used in schools.
In buildSequenced
Designs Instagram story sequences in a studio’s house style, then exports them as editable layers for Canva.
LaunchingFallow
A native iOS app blocker. Everything outside your daily free window stays locked, and you can’t talk your way out of it.
LiveNoteless
An AI notes app that grew from a smart notepad into an assistant that brainstorms with you and writes the notes itself.
ΦKleus
Turns the videos, books and podcasts you keep saving into 15-minute lessons, then checks in until you actually finish.

The decisions are mine. The typing isn't.
You bring the problem
A process that eats your week, an app idea, a tool your team keeps asking for.
I make every call
Scope, architecture, design, and what not to build. The decisions stay human.
AI does the typing
I steer Claude Code through the build. Fast, but never unsupervised.
You own all of it
The code, the accounts, the IP. No black boxes and no lock-in.
Fixed price · You own the code · No black boxes
