Sneho - Child Care Connect
Caregiver discovery and family safety platform for modern childcare. Match with verified babysitters based on proximity and personality, conduct live video screening interviews, and monitor active sitting sessions with real-time tracking.
Executive Summary
The Challenge
Trust barriers, unverified sitters, and absence of real-time monitoring when parents book in-home childcare.
The Solution
Haversine geospatial matching algorithm, Stream SDK WebRTC video interview rooms, and Socket.IO real-time GPS/SOS streaming.
Measurable Impact
Real-time session tracking, emergency SOS alerts, and collision-free booking calendar.
Technologies
Key Decisions
Why Custom Matching over generic search?
Childcare is sensitive to personality and special requirements. Scoring energy compatibility and schedule overlap upfront eliminates 80% of hiring friction.
Why Stream SDK for pre-hiring video interviews?
Building production-grade WebRTC with signaling, TURN/STUN servers, and multi-device support from scratch would derail core product focus. Stream SDK provided zero-overhead, highly reliable video conferencing.
Why MySQL with Prisma for bookings?
Childcare bookings require strict ACID transactions and relational foreign keys to prevent double-booking race conditions between concurrent parent requests.
Retrospective
Hardest Part
Synchronizing real-time session tracking, live GPS location updates via Socket.IO, and Stream video/chat states simultaneously without memory leaks or race conditions.
Biggest Insight
In marketplace platforms involving children, safety and trust features (SOS alerts, verified certifications, video screening) drive user retention far more than basic listing directories.
Do Differently
I would implement Redis Pub/Sub horizontally for Socket.IO clustering to scale GPS tracking across multiple server instances.
Key Highlights
Smart Match Engine
Compatibility scoring based on child energy levels, temperament harmony, special needs handling, and Haversine geospatial proximity.
