Mobile apps
iOS and Android apps from a single codebase with Expo and React Native, taken all the way to the App Store and Google Play.
I design, build and publish my own apps — iOS, Android, macOS and web.
After 13 years of shipping web and mobile software for others, I now build my own products: designed, coded and published end to end, on infrastructure I run myself.
Small, focused apps that solve one real problem well.
Release notes and build logs from my apps: what changed, and how it was built.

Fast, search-friendly web apps and product sites with Astro and Next.js, bilingual from day one.
From product idea to technical roadmap: codebase audits, architecture and technology choices, AI-assisted development workflows.
Self-hosted Appwrite on Hetzner behind Cloudflare: high availability, backups and the deploy tooling my own apps run on.
I am Yunus Senem, an independent app developer in Antalya. For 13 years I built web and mobile software for clients and teams; today my time goes to my own products.
I design, code and publish them myself: Expo and React Native on mobile, Astro and Next.js on the web, and a self-hosted Appwrite backend on Hetzner and Cloudflare that every app shares.
Each app solves one small, real problem: a business card that remembers who you met, groceries that don’t expire in the fridge, servers in the menu bar. I write about how they are built on the blog.
Feedback on an app, a collaboration idea or a technical question: e-mail is the fastest way to reach me.
