NACOS FUNAAB
Institutional platform for NACOS FUNAAB combining the public website, student payments, administration, events, and financial management.
Role & Contributions
As Software Director, led architecture and development. Built a public website and admin dashboard (Next.js) backed by an Express API. Includes Paystack payment integration, PDF receipt generation, role-based access control, financial reporting, expense tracking, and event management.
The Problem
NACOS FUNAAB needed centralized digital infrastructure for student communication and payment management. Previously relied on spreadsheets and manual processes.
Approach
Built unified platform: public website for students (payments, events, information), admin portal for staff (financial management, reporting), and Express API backend (business logic, payment processing).
Solution
Separated frontend applications by use case with different auth strategies (JWT for API, session-based for admin). Built duplicate prevention through compound indexes and atomic operations. Used background jobs for PDF generation and email.
