FAQs
I specialize in Android (Kotlin/Jetpack Compose) and iOS (SwiftUI/UIKit) app development, providing end-to-end services from planning and design to development, testing, and deployment. I also offer backend integration, API development, Bluetooth connectivity, push notifications, Firebase services, and cloud hosting solutions.
Yes, I develop native apps for both Android (Kotlin) and iOS (SwiftUI/UIKit). I also work with React Native for cross-platform projects when needed.
I assist with and complete the entire deployment process, ensuring your app meets Google Play and Apple App Store guidelines and handling metadata, screenshots, and compliance checks.
I follow a structured process:
1. Requirement Gathering & Planning
2. UI/UX Design (if needed)
3. Development (Agile Iterations)
4. Testing & Debugging
5. Client Review & Refinements
6. Deployment & Store Submission
7. Post-Launch Support & Maintenance
Timelines vary based on complexity. Simple apps may take 2-4 weeks, while complex apps with APIs, real-time features, or Bluetooth integration may take 2-3 months or more.
I charge an hourly rate of $150/hr, and project estimates are based on the scope and complexity. After an initial consultation, I can provide fixed-cost estimates for larger projects.
Yes, I offer ongoing support, updates, bug fixes, and feature enhancements to keep your app running smoothly after launch.
Absolutely! I have experience integrating payment gateways (Stripe, Apple Pay), Firebase services, Bluetooth LE devices, APIs, and various cloud platforms (AWS, GCP, Firebase, Supabase).
Yes, I can refactor, debug, optimize, or extend existing iOS or Android codebases.
I bring years of hands-on experience, a focus on clean and scalable code, and a deep understanding of native mobile development best practices. I don’t just build apps—I ensure they are efficient, user-friendly, and future-proof.
