Chiatiah Rayan Nguea, full stack engineer Rayan Studio
I build web and mobile apps for your business.
Building the future,
one line of code at a time.
I'm a full stack engineer who thinks in systems, builds with intention, and believes that great software is invisible. It just works.
The Story
I didn't plan to become a developer. I was born for it. That first "Hello World" felt like finding a superpower, the ability to build something out of nothing but logic and an idea.
Curiosity turned into obsession. Nights in documentation, mornings chasing errors that made no sense, afternoons where it finally clicked. Those hours taught me how software actually breaks, and no model has been able to hand me that.
Now I build with AI every day, and it changed my job more than it changed my craft. Typing got cheap. Judgment didn't. A model will give me five working answers and no opinion on which one my users need, which one survives the next feature, which one I'll regret in six months. That call is still mine.
So I still think the best code isn't the cleverest, it's the one the next person can maintain. And the best developers were never the ones who knew everything. They're the ones who know how to learn anything, which counts for more now that the answers arrive faster than anyone can check them.

The process behind every line of code
How I write and ship software that stays easy to change as the product grows.
- 1async function checkout(cart) {2 const order = await createOrder(cart)3 await chargeCustomer(order)4 return sendReceipt(order)5}
Clean code
Every function does one job, and complexity stays behind small interfaces. The next developer can read a file top to bottom and know what it does.
- v0.1Ship the first version
- v0.2Watch how people use it
- v0.3Fix what gets in the way
- v1.0Ship again
Ship early, then iterate
I get a working version in front of users quickly, then change it based on what they actually do instead of what we guessed.
Does this change make the product easier to use?

Every architecture decision starts with how it changes the experience for the person using the product.

Fast by default
I measure before optimizing, and I treat slow pages and janky interactions as bugs.
