About Clarence

Looking to quickly launch an MVP, a web/mobile application, or a business tool without going through an expensive and slow agency?

I can help you create modern, fast, and truly usable products: Flutter applications, React/Next.js web apps, admin dashboards, SaaS platforms, marketplaces, internal tools, and Firebase/Stripe integrations.

I am CTO and co-founder of Bloomy, a marketplace for personalized bouquets connecting customers and florists. On this project, I designed and developed a complete architecture including:
• Flutter web/mobile application
• Firebase backend (Auth, Firestore, Storage, Cloud Functions)
• Professional dashboard
• Inventory management system
• Stripe Connect
• Marketplace logic
• Web and mobile deployment
• UX/UI optimization
• Automations and advanced features

This experience allows me to understand the real needs of a product: move fast, build the right features, keep the architecture simple, and create a modern and fluid user experience.

I can help you with:
• MVP creation from A to Z
• Flutter / Firebase development
• React / Next.js development
• Admin dashboards
• iOS/Android mobile applications
• SaaS web apps
• Stripe and payment integration
• Marketplaces
• Internal tools
• Automations
• UX/UI improvement
• Bug fixing and optimization of existing applications

I place great importance on visual quality, execution speed, and clarity of communication. My goal is to build clean, scalable products that can be quickly tested with real users.

Available for one-off missions, startup coaching, or MVP development.
