Revna
AI skin routine coach
Role: Mobile developer · 2025
Overview
Revna is an AI-assisted skincare routine product for iOS and Android. I worked on the Flutter application, API-driven flows, localization, reminders, privacy controls and the Supabase-backed production system.
Product scope
Guided mobile flows
API-driven onboarding, routine and user-state experiences in Flutter.
Localization
Product copy and flows prepared for multiple languages.
Reminders
Scheduled product interactions connected to routine state.
Privacy controls
User-facing consent, storage and deletion controls.
Store delivery
Production builds, review requirements and post-release updates.
The problem I owned
The product needed to coordinate guided mobile flows, user state, reminders and privacy-sensitive data across the Flutter client and Supabase services.
What I built
- Developed API-driven mobile features in Flutter: guided flows, user state, reminders.
- Implemented full localization and privacy-first user controls.
- Built the production backend on Supabase — Edge Functions, PostgreSQL/SQL and database triggers.
- Managed the release across App Store Connect and Play Console.
Key takeaway
Privacy requirements are most effective when reflected in product defaults, user controls and the data layer together.
