I’m a Senior Mobile & Software Engineer with 8 years of experience in mobile app development and web development. I specialise in iOS app development, Android app development, Flutter, React Native, and .NET MAUI. I build custom mobile apps, cross-platform apps, APIs, backend systems, and third-party integrations. Whether you need an app developed from scratch, an existing app redesigned, bugs fixed, or new features added, I provide clean, scalable, and reliable solutions. My team also covers UI/UX design, backend, web development, and QA for complete end-to-end development.
