Co-built with a Franco-Senegalese client, C² (“c’est carré”) is the first digital ecosystem fully dedicated to textured hair care, launching in December 2025. It combines intelligent recommendations, advanced geolocation, real-time booking, and specialized e-commerce to modernize a beauty market that has long been underserved.

Discovery in textured-hair care is still trial-and-error, while stylists lack tools tailored to their workflows and business growth. The client needed a marketplace that improves matching quality, streamlines booking, and supports commerce and analytics in a single product.

Diakitech delivered product strategy, UX/UI, full-stack marketplace engineering, ML-based matching, geospatial logic, and security-first infrastructure.

✓ Intelligent Recommendation: ML-based matching with 15+ compatibility criteria ✓ Real-Time Booking: scheduling, conflict detection, instant sync ✓ Advanced Geolocation: optimized mapping with intelligent clustering ✓ Interactive Visual Portfolio: auto-tagged galleries, before/after comparisons ✓ Integrated E-Com: marketplace with promotions and inventory tracking ✓ Analytics Dashboard: revenue, segmentation, client insights ✓ Business Intelligence Tools: predictive trends, KPI tracking, custom reports ✓ Secure Communication Hub: messaging, push notifications, reminders ✓ Payment System: tips management, automated invoicing, full checkout flow ✓ Client History Management: geotagged photo timeline + preference tracking

➝ Frontend: React 18 + TypeScript (strict), Tailwind CSS, Framer Motion ➝ Infrastructure: Firebase Authentication, Firestore, Cloud Functions, global CDN ➝ State Management: React Query, Context API, React Hook Form + Zod validation ➝ Geospatial Tech: Leaflet + React-Leaflet with advanced geocoding ➝ Performance: PWA, code splitting, lazy loading, multi-level caching ➝ Component Architecture: 40+ components (Radix, shadcn, WCAG 2.1 AA) ➝ Security: Firestore granular rules, server-side validation, smart rate limiting

C² removes guesswork from salon discovery through proprietary matching and real-time availability, while giving stylists an operating system for booking, business insight, and commerce. The platform is designed to stay smooth and reliable even under heavy marketplace usage.

We engineered C² as a specialized, scalable marketplace—not a generic booking app. By combining ML matching, geospatial intelligence, and a modular serverless core, we turned industry pain points into a product that feels effortless for clients and powerful for professionals.
