TPMS Expertic | Project

InternalTPE operations management platform / 2025

Problem

Expertic needed one place to coordinate interventions, consumables, network checks, deblocking, installations, replacements, stock movement, and dead stock with traceability and role-aware access.

Solution

Build a multi-role web platform with a Next.js dashboard, NestJS API, and Prisma/PostgreSQL model. The backend enforces JWT auth, CASL permissions, validation, notifications, uploads, and role-scoped APIs.

Key Features

Role-based dashboards for bank employees and account managers

Ticket workflows for interventions, consumables, network checks, and deblocking orders

TPE catalog, terminal model, bank, client, consumable, and dead stock management

JWT authentication, CASL authorization, route guards, validation, and role-scoped APIs

SSE notifications, email templates, attachments, and Excel template import/export

Searchable/filterable tables, reusable modals, settings pages, and unsaved-change protection
