Frequently asked questions.
Quick answers about how we engineer, deliver and operate web & mobile applications.
01Do you build native or cross-platform mobile apps?
Both. We use React Native for cross-platform delivery, and Swift / Kotlin for native modules where performance, sensors or platform APIs require it. For App Store and Google Play we handle the full submission, review and release flow.
02Which web frameworks do you use?
Next.js (React) for production-grade web applications, Vite + React for SPAs, and WordPress + headless setups for content-heavy sites. State management with Zustand or Redux Toolkit, styling with Tailwind, forms with React Hook Form.
03Can you publish to App Store and Google Play?
Yes — we have shipped multiple production apps to both stores including e-Ninni, Sell-R, e-Yarışma and the macOS app Wallnetic. We handle developer accounts, app review, store listings, screenshots and metadata localization.
04Do you build progressive web apps (PWAs)?
Yes. PWAs are a strong fit for content-heavy or offline-first products without store overhead. We implement service workers, caching strategies, push notifications and installable manifests.
