01
Overview
OpusLab is a digital training school. It needed a single system to manage finances, students, staff, and trainers instead of scattered tools.
I designed and built a custom ERP during my bachelor's internship, with dedicated experiences for three roles.
02
My contribution
- Designed and built the ERP to manage finances, students, staff, and trainers.
- Implemented features for Administrator, Trainer, and Marketing Manager roles.
- Built dashboards with Recharts and an API with Node.js and Express.js.
- Containerised the application with Docker for deployment on AWS.
03
Key features
Administrator
HR, financial transactions, training sessions, and certificate generation.
Trainer
Assessments, calendar, and pedagogical follow-up of learners.
Marketing Manager
Advertising campaigns and performance dashboards.
04
Architecture & decisions
- Role-based views keep each user focused on their own tasks.
- A document database fitted the evolving shape of school records.
- Docker made the environment reproducible from development to AWS.
05
Challenges & solutions
- Three very different user roles
- Separated features by role at both the API and interface level.
- Certificate generation
- Generated certificates from session and learner data to avoid manual edits.
06
Results & learnings
- Translating real business processes into software.
- Owning a product from design to deployment.
