Full-stack product engineer specializing in mobile apps and scalable backend systems. I build mobile apps for iOS and Android, from startup MVPs to production-grade apps that need a serious refactor. Whether you need a cross-platform app built with React Native, a clean architecture overhaul, or a web dashboard to complement your mobile product, I handle the full scope: UI, logic, APIs, and deployment. My process starts with understanding your users and business goals before writing a single line of code. I follow scalable architecture patterns, write clean, maintainable code, and communicate consistently throughout, so you always know where the project stands. Every delivery goes through thorough testing across devices before it reaches your users. If you're ready to build something solid or fix what's broken, send me a message with a brief overview of your project. I typically respond within a few hours and offer a free discovery call to make sure we're the right fit before you commit.
