nowby.co →I'm Berkay Doğan, a published writer and developer. I design and build iOS apps, websites and live data products, from the first sketch to the App Store, and I write every word on the screen as carefully as a line in a book.
Available for remote projects in the Netherlands, the UK and across Europe.
Have a project in mind?What I build
Native SwiftUI apps with maps, audio, location and live updates, designed for the latest iOS and shipped to the App Store.
Fast, accessible sites and web apps in Next.js: portfolios, product pages, bilingual sites, dashboards.
Postgres and Supabase backends, realtime updates, scheduled jobs and APIs that stay quick under load.
Interfaces translated and checked in up to 30 languages, with copy that reads naturally in each.

About writtenby. →How we work
You tell me what you need; I ask the questions that shape the scope.
A written scope with what will be built, what won't, and a fixed price.
A working build to try every week, so nothing surprises you at the end.
Store submission, launch, and fixes after release.
Principles
No dark patterns. No manipulative design, no endless feeds by default. My own apps run without ads or likes.
Words matter. Every button, empty state and error message is written, not filled in.
Small and direct. You work with the person who designs and builds your product.
Write a few lines about what you'd like to build. I reply personally.
