DO NOT HIRE A FREELANCER WHO JUST WRITES CODE. HIRE A PARTNER.
Most mobile apps fail because they crash under load or get rejected by the App Store due to fragile code architecture. If you are a founder or business owner, you need clean, scalable native apps.
I engineer production-grade iOS and Android mobile applications designed for user retention, security, and technical longevity.

FAQ
Will I own the source code and intellectual property?
Yes, absolutely. Upon final project delivery and milestone completion, full ownership of the source code and all intellectual property rights transfers entirely to you. You will have full access to the repositories.
Do you develop native apps or cross-platform apps?
I build both depending on your budget and goals. I specialize in native apps via Kotlin (Android) and Swift (iOS) for maximum performance, as well as cross-platform apps using Flutter for multi-platform efficiency.
How do you ensure the mobile app passes App Store reviews?
I engineer all applications in strict compliance with Apple’s Human Interface Guidelines and Google Play's Developer Policies. I handle the configuration and guide you directly through the store submission process.
Can you integrate advanced AI capabilities into the app?
Yes. I regularly implement advanced AI integrations, including OpenAI API, Gemini, and Claude services. This covers everything from intelligent chatbots and semantic search to automated data processing tools.
Will I receive the complete source code?
Yes. The completed project can include the source code and relevant project files according to the package and agreement. You will be able to access and maintain your application after delivery.
Can you build an MVP first?
Absolutely. If you are validating an idea, I can build a focused MVP with the essential features first, giving you a practical foundation to test and expand later.
Can you integrate APIs or third-party services?
Yes. I can integrate REST APIs, payment services, authentication systems, databases, and other third-party services required for your app.
Can you build payroll management apps?
Yes. I can develop payroll solutions with features such as employee management, salary calculations, payment workflows, payroll records, notifications, and API integrations based on your requirements.
Will you develop both Android and iOS apps?
Yes. I develop native Android apps using Kotlin and native iOS apps using Swift. I can also build solutions that connect both platforms to the same backend and APIs.
Can you help publish my app?
Yes. I can assist with preparing your application for Google Play and the Apple App Store, including required configurations and submission guidance.
