CloudCampus - AI-ready Multi-Tenant School ERP SaaS.

CloudCampus is an AI-ready multi-tenant School ERP SaaS platform for schools, trusts, and multi-campus organizations. It includes tenant onboarding, role-based access, secure authentication, tenant isolation, student/staff workflows, academic setup, attendance, homework, exams, fees, notices, audit logging, and deployment-ready architecture.

Problem

Schools need centralized digital workflows for academics, staff, students, parents, fees, communication, documents, and administration. Manual operations make reporting, access control, and multi-campus expansion difficult.

Solution

CloudCampus models schools as a multi-tenant SaaS platform with role-specific portals, secure onboarding, tenant and school access context, API-first workflows, and deployment documentation for controlled staging environments.

My Role

Founder, backend engineer, and product engineer. I own product scope, backend architecture, API design, tenant isolation decisions, deployment readiness, and roadmap planning.

Business Value

CloudCampus can reduce manual school operations, centralize academic management, support multi-campus growth, and create a SaaS business opportunity for school operations digitization.

Backend Architecture

Presented only from visible repo evidence: Java/Spring Boot backend, REST APIs, authentication and authorization, role-based access, multi-tenant design, database schema, tenant isolation, audit logging, deployment docs, Docker-oriented structure, and GitHub Actions workflows.
