How a project runs
From the first message to updates on Google Play, you know what happens at every step.
- 1
Kick-off
I listen to what you want to build, we list the features together and I write down the scope and the timeline.
- 2
Design
I sketch the screens and the user flow, and get your approval before any code is written.
- 3
Development
I build with Kotlin and Compose and upload test builds so you can try them on your own phone.
- 4
Launch
I take the app to Google Play, including the store listing, privacy policy, Data safety form and the review.
- 5
Maintenance
I keep your app up to date with new Android versions, target API requirements and policy warnings.
About me
Hi, I’m Oğuzhan.
I studied Management Information Systems at Anadolu University and trained in web design and programming. I have worked in software, technical support and research roles at several technology companies.
Today I focus on Android: I publish my own products and maintain them, from Play Console policies to new Android versions. I bring the same care to client projects.

Let's talk."}

FAQ
It depends on the scope. A simple single-purpose tool ships quickly; an app with sign-in, payments and notifications takes longer. In our first call we list the features together and I send you a written timeline.
