Problem

Selfie-based skin analysis is at the mercy of lighting and camera quality. Skinlav wanted objective measurements from sebum and desquamation test strips that a customer applies to the forehead and cheeks, then photographs.

The analysis runs on the phone, and its result follows the customer from the app into the order, so the shop knows what each purchase was recommended for.
  • Flutter mobile app that guides the test, captures the strips and runs custom models on the device to measure sebum and desquamation per facial zone and derive the skin type.
  • Model training and conversion pipeline in Python (PyTorch to TFLite and ONNX) for on-device inference.
  • Next.js and TypeScript store on Stripe’s product catalogue with incremental static regeneration; the app hands its analysis to the store by deep link, and it travels with the order into Stripe Checkout.
  • Native Windows and macOS CRM (Flutter desktop), a full replacement for Bitrix24 with the data migrated over: deals, six-zone diagnostics, ingredient stock, Stripe payment links; a local ObjectBox database synced through Google Drive with a single-writer lock, and over-the-air updates on both platforms.
  • Flutter Web stock manager with batch and expiry tracking and a full audit trail.
  • Firebase backend: Cloud Functions, Firestore, Auth, Storage, Remote Config, Hosting.
