I build high-quality mobile apps that are fast, scalable, secure, and user-friendly.

Android Development — Kotlin & Java 2. Flutter & React Native — Cross-platform applications 3. Firebase — Authentication, Firestore, FCM, Storage, Analytics & Crashlytics 4. REST APIs & Third-Party API Integration 5. GPS & Location-Based Applications 6. Real-Time Chat & Notifications 7. Audio/Video Calling — Twilio, Agora and similar solutions 8.

Play Store Deployment & Release Support 💡 My Approach I focus on clean, maintainable, scalable code and building applications that are reliable and production-ready. Before starting a project, I can also create a small demo / Proof of Concept (PoC) for the required feature, so you can see and verify the functionality before moving forward with the complete development. Whether you are: → Building a new mobile app → Adding features to an existing app → Integrating Firebase or APIs → Fixing bugs or performance issues → Adding AI-powered functionality I can help you take it from idea → development → testing → production. Let's discuss your project and build something reliable together.
