The problem
Madrasas and schools run on paper registers and spreadsheets; existing tools ignore their curriculum, fee structures and language.

What I built
- Two-layer tenant isolation: a Prisma extension scopes every query by institution, backed by Postgres RLS set per transaction.
- Automatic wildcard subdomain per signup plus self-service custom domains through Cloudflare for SaaS with DNS-TXT verification.
- Super-admin control plane and tenant ERP in one NestJS modular monolith, with tenant impersonation.
- Module marketplace with entitlement guards, per-student capacity limits and metered SMS.
- Money-safe finance and payroll: ledger posting, reversals and race-free guarded increments.
- Secure R2 storage: presigned uploads plus server-side WebP re-encoding and EXIF stripping.
