Customer Survey App

A customer-satisfaction survey platform for construction projects, used by multiple firms and their clients. Stakeholders rate the contractor across several categories; the system computes weighted scores automatically and produces PDF/CSV reports — surveys are distributed by QR code and submitted through a public form.

Overview

Replaces paper-based satisfaction surveys with a digital workflow: clients and stakeholders rate the contractor across multiple categories, scoped per project and survey period. Built as a shared product rather than a one-off, it runs for several firms and their customers.

Role

Full-stack — React/TypeScript front end, .NET back end.

Highlights

• Multi-category feedback — six rating categories (site performance, personnel, design management, safety/WSHE, quality/QMS, and more), each with several metrics, plus a flexible metric-category structure for evolving survey templates.
• QR distribution + public form — surveys shared by QR code and filled in through a public submission form, tied to project, survey period and respondent.
• Data pipeline — transforms nested category/metric responses into a flat grid structure, so a large survey reads as a single clear table.
• Automated scoring — per-category averages rolled up into a weighted overall score.
• Admin dashboard — Compact, Normal and Tree views over the responses (AG Grid), with a detail modal, status bar and project filtering.
• Reporting — one-click PDF / CSV export for stakeholder reports.
• Architecture — React 18 micro-frontend (RSBuild + Module Federation) on a .NET 7 / EF Core / PostgreSQL backend, RESTful repository-pattern API with role-based permissions.

Outcome

Digitised the whole satisfaction-survey loop — from QR distribution to weighted scoring and stakeholder reporting — as a shared platform across multiple firms and their clients.
