Edtech · Flutter Cross Platform Mental Health App
Peakmind
Multi-platform mental health & wellness SaaS (Flutter B2C student app + Next.js B2B counsellor dashboard + serverless.
The brief
Accelerate feature velocity on a live mental health app serving students across multiple institutional clients (Allen, JMR), hardening the existing Flutter codebase, instrumenting analytics, building out a counsellor B2B dashboard, and expanding the product with AI-driven mood tracking, assessments, and monetisation capabilities.
What we built
A full-stack mental health platform with a Flutter cross-platform app (iOS, Android, PWA) featuring mood tracking, AI chatbot (Peakoo), assessments with CQ reports, sleep improvement, self-learning courses, challenges, and live meditation via Zoom. A separate Next.js B2B counsellor/supervisor dashboard was built for institutional clients. The backend is a Node.js serverless monorepo on AWS Lambda with Prisma ORM, multi-environment CI/CD, and Postgres. Deep B2B integrations were built for Allen EdTech (white-label Flutter embed with bidirectional JS bridge), JMR, and Zoho session booking. A Razorpay freemium paywall was added late in the engagement. PostHog analytics were instrumented across 100+ events with episode-level tracking across all app surfaces.
Production Flutter app (iOS App Store + Android APK + PWA) with mood tracker, AI chatbot Peakoo, CQ assessments with paid reports, sleep feature, live Zoom meditation, session booking via Zoho, self-learning courses, challenges, and a white-label embed for Allen EdTech. B2B counsellor/supervisor Next.js dashboard live for institutional clients. Razorpay checkout and freemium home screen gating live. 100+ PostHog events with episode tracking across all surfaces.
