I turn ideas into shipped products.

I have been building products for iOS, Android and the web since 2018. I handle development, app store releases and search visibility end to end.

Shipped product experience
I have published 11 apps on the App Store and Google Play. I learned the store review process by living through it.
End-to-end ownership
From the interface to the backend (Firebase, Supabase), from design to release, I have worked at every stage of a product.
Technical and marketing
I know SEO and ASO; right now I run the SEO work for 2 brands. A product should not just work, it should be found.
I learn fast
Python → Java → Swift → Kotlin → Flutter. I shipped a published product with each one.

My own product

Mobile app · iOS & Android

Vakti Geçmeden

An app that cuts food waste by letting businesses sell their end-of-day surplus at half price. Beyond the development, the brand identity, website and marketing are mine as well.

E-commerce · iOS & Android

Cepte Perakende

An e-commerce app where I built the entire shopping journey on my own — from the catalogue to instalment payments, from the distance selling agreement to the returns flow.
