Smart Sitting — Childcare Marketplace Platform 3x Platform Growth
Built and continue to maintain a full-stack childcare marketplace connecting families with vetted sitters, featuring real-time booking, background checks integration, and a provider management dashboard — alongside a companion React Native mobile app rated 4.8★ on the App Store.
The Challenge
Smart Sitting needed a reliable, scalable platform to match families with childcare providers across multiple markets. The system required real-time availability, secure payment processing, provider vetting workflows, and a mobile-first experience—all while maintaining trust and safety standards critical in childcare.
Our Solution
We architected a full-stack solution with an Angular frontend and Node.js backend, integrated Stripe for secure payments, built a real-time booking engine, and developed an admin dashboard for provider onboarding and background check management. The platform was deployed on AWS with CI/CD pipelines for rapid iteration.
