Loyalty management system

B2B back office · team project · 2026

What it is
An admin system for business loyalty programmes: cards, customers, promotions and coupons managed in one place. The project is confidential, so data in the screenshots is masked and the description is short.
Status
Actively developed.

Cards and customers

Everything about a card and its owner on one screen: the list on the left, the selected record on the right.

Promotions

Promotions can be created and tested before they go live.

Technical side

Role
Lead frontend developer in a team with a backend developer, plus part of the backend work.
Decisions
  • The API client is generated from the backend's OpenAPI description, so frontend and backend types always match.
  • Menus, tabs and route protection are built from a single definition based on the user's permissions.
  • Integration tests check screens with different role permissions.
Scale
3 languages · ~730 frontend tests
Stack
React, TypeScript, RTK Query, AG Grid, Tailwind CSS, shadcn/ui · .NET, SQL Server · Vitest, Playwright
