Sayun Das

I am an independent Flutter app developer and product builder with hands-on experience in designing, developing, and launching real production-ready Android applications.

I specialize in building mobile-first SaaS apps using Flutter and Firebase, focusing on clean UI, performance, and real business use cases — not just demo projects.

My core skills include:

• Flutter & Dart development
• Firebase Authentication & Firestore
• Admin panels (user management, premium control)
• OCR-based mobile apps
• Offline-first architecture with cloud sync
• Play Store–ready deployment

I have built and published multiple apps on the Google Play Store. One of my key projects is ScanUp, a professional contact manager designed for sales agents, consultants, and small business owners. ScanUp includes OCR business card scanning, follow-up reminders, cloud backup, exports, and an admin-controlled premium activation system.

I work with a product mindset, meaning I understand not just coding, but also:

• Feature planning
• User flow design
• Monetization logic
• Scalability considerations

I can help clients build:

• Complete Flutter Android apps
• Firebase backends
• Admin dashboards
• MVPs and production-ready SaaS products

I prefer clear communication, realistic timelines, and long-term value creation. If you are looking for a developer who can take ownership and deliver a working product — not just code — I’d be happy to work with you.
