Rebuilding a Failing Social App for Women

TOUT TechnologiesFounding Engineer (Full-Stack)Apr - Aug 2025 (4 months)

Took a crashing React Native app from 0 to first stable alpha with 10 users in 3 months.

Launch
First stable alpha in 3 months
Crash Reduction
40% faster diagnosis
Security
10+ users, zero unauthorized access

Context

TOUT is building a women-only social platform. When I joined as the first engineer, the React Native app was failing in production—crashes, broken flows, no observability. The founding team needed someone who could rebuild the entire stack and get to a stable alpha for their first user cohort.

Stage
Pre-seed, 0 to alpha
Team Size
Solo engineer, working with 2 founders

The Challenge

Unstable codebase: App crashed frequently with no error tracking or monitoring

Security gap: No way to enforce women-only access at signup

Zero observability: No insight into what was breaking or when

Timeline pressure: Needed to launch alpha for first 10 users in 3 months

What I Did

Rebuilt the app from scratch

React Native, TypeScript

  • Refactored core navigation and state management
  • Fixed memory leaks causing crashes
  • Established component library for consistency
  • Set up CI/CD pipeline for automated testing

Designed invite-only onboarding with OTP verification

Custom auth flow

  • Built custom auth flow enforcing invite codes
  • Integrated Twilio for SMS-based OTP
  • Protected community integrity before scaling
  • Created admin tools for invite management

Integrated observability stack

Sentry, Grafana, Prometheus

  • Set up error tracking and alerting
  • Built custom dashboards for user behavior
  • Reduced crash diagnosis time by 40%+
  • Implemented real-time monitoring for critical paths

Impact

Delivered first stable alpha on time

Got to 10 users in 3 months with zero critical bugs

Onboarded first 10 women users

Zero unauthorized access, protected community integrity

Enabled team to diagnose issues 40% faster

Accelerated iteration and reduced downtime

Set foundation for scaling

Architecture ready for 100+ users post-launch
