A multi-tenant enneagram testing platform I built single-handedly: answer ~81 questions and it auto-generates a 30+ page personality report in the background. Sold to institutions via licenses and still live on bitatesti.com.
Tech stack
On a custom request, I single-handedly built — end to end — a custom, multi-tenant enneagram personality-test platform. A user answers ~81 questions and the system instantly produces a detailed 30+ page personality report as a PDF. The platform is live today on bitatesti.com.
Institutions (HR, school guidance, etc.) needed to run scalable, auditable and reportable personality tests across many people. I designed this as a license-based SaaS with role- and department-based access.
A panel admin sells "N-person" licenses to institutions. An institution registers with its license code and automatically emails one-time test codes to its people; they log in with the code, take the test, and reports are generated automatically in the background. Institution managers and sub-responsibles access only the relevant people's reports per their authority and assigned departments. (ASP.NET MVC + Entity Framework + SQL Server; layered architecture.)
The backend rests on a rule/expression engine where enneagram formulas can be written flexibly. The question pool can be changed and per-type answer mappings are fully configurable. Reports are produced with iTextSharp from a template.
The resulting product has been used everywhere from HR hiring based on personality reports to school counselors steering students toward fields they are genuinely talented in — and it is still active. It is a working SaaS product written entirely by a single developer.
I build licensed, multi-tenant web platforms with automatic PDF reports and role-based access, end to end.
