Learning Platform with Certificate Verification
Excelia Academy
Excelia Academy teaches AI, web and app development, PMP and IT skills through recorded courses. A video library alone doesn't make an academy — what makes it one is enrolment, progress, and a certificate an employer can actually check. We built all three, plus the portal instructors use to publish their own courses and the console the academy runs it from.
01 — The brief
The challenge
Excelia needed a platform that served three completely different audiences at once: students browsing, enrolling and working through lessons; instructors building and managing their own courses; and administrators approving applications, tracking payments and managing users. On top of that, a training certificate is worthless if nobody can verify it — so every certificate issued needed a public, tamper-resistant way for an employer to check it.
02 — What we built
The solution
We built a React and TypeScript single-page application on Firebase, with role-based access separating student, instructor and admin experiences. Students get a catalogue, enrolment, a personal dashboard and a lesson player; instructors get a portal to create and manage their courses; admins get a console for courses, users, payments and applications. Each completed course issues a certificate with a unique code that resolves at a public verification URL, so an employer can confirm it without contacting the academy.
03 — Method
How we got there
- 01Designed a Firestore data model across users, courses, lessons, enrolments, payments and certificates
- 02Built role-based routing and access control for student, instructor and admin experiences
- 03Shipped the student journey — catalogue, category filters, enrolment, dashboard and lesson player
- 04Built an instructor portal for creating, publishing and managing courses independently
- 05Built an admin console for course approval, user management, payments and applications
- 06Implemented public certificate verification, where a unique code resolves to a shareable proof URL
- 07Added a pending/approved/rejected approval workflow across course and application submissions
04 — Proof
What changed
- Three role-based experiences — student, instructor and admin — in one platform
- Publicly verifiable certificates, checkable by employers without contacting the academy
- Self-serve instructor portal, so new courses ship without developer involvement
- Approval workflow giving the academy control over what gets published
