Achieva Africa

Overview

Engineering a multi-tenant talent marketplace for African schools and educators.

Achieva Africa came to Nuelsville Technologies needing an end-to-end digital marketplace that could bridge the gap between verified teaching talent and institutions seeking top-tier educators. The system required complex multi-role workflows for teachers, school administrators, and system admins, as well as a flexible credit system (Keys) to monetize candidate unlocks and applications.

We built and delivered the entire ecosystem — including a high-converting marketing portal (achievaafrica.com), a modern Next.js web application (app.achievaafrica.com), a NestJS REST API with PostgreSQL and Prisma ORM, Paystack payment integration with real-time webhooks, automated email notifications via Resend, and candidate profile masking to protect privacy while enabling instant recruitment.

Monetization & Wallet Engine
