Client and context

A digital parenting support product designed to launch as a subscription-based SaaS platform.

Business problem

The system had to combine AI conversations, recurring billing, and content workflows in one reliable product that could evolve quickly without billing or data risk.

Approach and solution

I designed a modular architecture with dedicated domains for auth, chat, content, and billing. Priority was continuity of conversations, correct access logic, and fast feature iteration.

Delivery scope

  • Data model for accounts, child profiles, conversation history, and editorial content.
  • End-to-end Stripe lifecycle: checkout, webhook processing, billing state, and access control.
  • API layer for chat, blog, and account management with JWT-based authorization.
  • Docker + PostgreSQL + Redis deployment stack prepared for operational scaling.

Business impact

  • A launched product able to monetize early traffic from day one.
  • Architecture that supports safe expansion of AI and content features.
  • Delivery setup enabling new releases without reworking core modules.
