About this gig
Have an app idea and need a developer who can actually deliver it? I build Android, iOS, and cross-platform apps using Flutter from scratch, from a Figma design, or by fixing and improving an app you already have.
I work with startups, small businesses, and individual founders, handling everything from UI to backend integration (Firebase, REST APIs) to getting your app live on the Play Store and App Store.
What I can build:
Business and e-commerce apps, on-demand apps (food, grocery, taxi), booking systems, social and chat apps, health & fitness apps, education apps, and AI-powered apps with chatbot integration.
How I work:
We discuss your idea and requirements, I plan the architecture, build the UI, integrate the backend, test everything, and prepare the app for store submission. I also offer post-launch support bug fixes, updates, and new features whenever you need them.
Send me your requirements or existing app, and I'll get back to you with a clear plan and timeline.
