Software studioTaking on new projects
Software built bythe peopleyou talk to.
Codion is a two-person studio. We build web and mobile products for clients, and ship our own.
(01)Why Codion
We are two frontend engineers who spent years shipping interfaces for banks, architects, coffee chains and startups. Codion is where we do that work under our own name, and where we build the products we wanted to exist.
(02)What we do
Four things, done properly.
We keep the list short on purpose. These are the things we have done for years and do well.
02
Mobile apps
Cross-platform apps with React Native, from the first prototype to release on the App Store and Google Play.
- React Native
- iOS & Android
- Store release
03
Design systems
Tokens, components and documentation that keep design and code in step, so teams ship consistent interfaces faster.
- Design tokens
- Component libraries
- Figma-to-code parity
- Documentation
04
Interface motion
Scroll choreography, transitions and micro-interactions that make a product feel alive without slowing it down.
- GSAP
- Motion
- WebGL & shaders
- Reduced-motion support
(03)Before Codion
Work we shipped before this studio had a name.
Codion is new. The two of us are not. These are projects we built in earlier roles; the recognition belongs to the projects and the teams behind them.

(04)Our products
We build our own, too.
Running products of our own keeps us honest about what it takes to launch, support and improve one.
All products
(05)How we work
A short path from idea to release.
01
Listen
We start with the problem, the people who will use the product and what done looks like. You talk to the two of us from the first call.
02
Shape
We agree on scope, architecture and a plan in plain language, then show early prototypes instead of long documents.
03
Build
We work in short cycles with a preview link you can open at any time. The people who planned it are the people writing it.
04
Ship
We launch, measure and tidy up. After release we stay around for the next round of work.
(06)The studio
Two people. That's the whole team.
No account managers, no hand-offs. You talk to the people who plan it, write it and ship it.
