1. The Identified Problem
Private and public schools struggle with fragmented legacy software, brittle spreadsheets, and severe communication latency with parents regarding student attendance and tuition status.

2. Solution Engineered
A multi-school management platform for Benin: 4 apps, one per role (super admin, principal, teacher, class coordinator), covering per-class attendance, QR code check-in, grades and report cards, student follow-up, payments and reminders, and parent updates over WhatsApp or SMS.
3. Results & Measurable Impact
Built in 3 months, with strict per-school data isolation (PostgreSQL Row-Level Security) validated by concurrency and load tests before going to production.
My role
- Lead developer of this M&T Tech product: scoped the MVP around 4 roles and the core needs (attendance, check-in, grades, follow-up, payments, parents).
- Architecture: monorepo with a single NestJS API and 4 Next.js apps, PostgreSQL 16 with Prisma, Redis and BullMQ for background jobs.
- About twenty business modules, per-school isolation through Row-Level Security, Excel import/export and report cards.
- SMS and WhatsApp integrations with automatic fallback; security: role-based access control, rate limiting, audit log.
- Unit, end-to-end and load tests; WCAG 2.1 AA landing page; Docker production setup and rollback runbook.
