Visit green-delta.comThe challenge
Green Delta wanted to track how customers felt after claims, renewals, and branch visits.
It had customer data and an SMS gateway, but no way to survey at scale, enforce one answer per customer, or compute a defensible score.
What we built
Requirements, architecture, and the full system in fifteen weeks.
- 01
Backend API
With an SMS job queue and row-level tenant isolation.
- 02
Staff web application
For surveys, customers, sending, and reporting, with three roles.
- 03
Respondent page
That opens from the SMS link, down to a 320 pixel screen.
- 04
SMS adapter
That is provider-agnostic, with a full simulator.
Key features
Mandatory NPS question
The 0 to 10 score plus text, Likert, and choice questions.
