Hey 👋 I’m Anastasiia, a Senior Software Engineer specializing in cross-platform React Native app development for operations platforms, SaaS products, and real estate / field-service teams, from MVP to production-ready apps on iOS and Android. I help teams turn product ideas into stable, scalable mobile systems that users actually rely on daily. 🚀 What I Build with React Native Cross-platform mobile apps (iOS + Android) with a mobile-first UX Offline-first workflows with reliable data sync Push notifications (real-time updates, alerts, user engagement) Payments & subscriptions (in-app purchases, Stripe, Apple/Google Pay) Maps, geolocation & route-based features BLE / device integrations when hardware is involved Secure API integrations (often with .NET / REST / GraphQL backends) Admin dashboards (web companion panels for operations teams) 🧠 How I Work Discovery → clarify product goals, users, and edge cases Architecture → define scalable mobile structure (state, data flow, API design) Milestone delivery → iterative builds with clear scope per stage Weekly demos → working builds you can test continuously Store release → full App Store / Google Play preparation and deployment 💡 Why this approach works You get a production-ready architecture early, not just UI screens The app is designed to scale from MVP → full platform without rewrites Mobile performance, reliability, and UX are treated as core requirements, not afterthoughts You always know what’s being built and why, at every step If you already have an app idea, a prototype, or even an existing codebase, share it with me. I’ll map out the fastest and cleanest path to get it into production.
