Face-to-face, long-term work in Izmir
Since I am based in Izmir, meetings, test days and user training for Izmir projects are held on site; after launch, you keep working with the same person in the same city. I also build enterprise field and warehouse apps for manufacturers in Atatürk OSB, Kemalpaşa and Torbalı.
Types of mobile apps I build
- MVPs for startups: iOS and Android app + admin panel
- Ordering, loyalty and campaign apps for brands
- Enterprise field, warehouse and service apps
- Apps with AI, camera and barcode features
- Mobile apps that connect to your existing web system
Process and on-site work
Discovery, scoping and setup meetings are held on site; design and development progress through weekly demos, and you see every stage in a test environment. After launch, App Store and Google Play updates and new features continue with the same person. Details: mobile app development, enterprise mobile app.

Frequently asked questions
How long does mobile app development take in Izmir?
An MVP-scope iOS or Android app is typically store-ready in 4–8 weeks; for enterprise and integration-heavy projects, the timeline is given in writing together with the scope.
Do you meet in person?
Yes. On-site meetings in Izmir are scheduled for the discovery, setup and training stages; development proceeds remotely with weekly demos.
Do you build for both iOS and Android?
Yes. iOS apps are built natively with Swift/SwiftUI and Android apps with Kotlin; PWA is recommended for suitable projects.
Why a freelance developer instead of an agency?
You work directly with the person writing the code, with no communication loss and no cost of agency layers.
