Enterprise leave management for institutions

Educational institutions require robust, professional leave management systems with strict role-based workflows, automated reporting, and uncompromising audit trails.

The Solution

I architected and deployed a multi-tenant Software-as-a-Service (SaaS) solution using Python and FastAPI. This application provides a highly secure, isolated environment for multiple institutional clients to manage leave requests at scale.

Architecture Highlights

• Multi-tenancy Model: Implemented logical data separation using PostgreSQL Row-Level Security (RLS) to ensure data isolation between different institutions on a shared database instance.
• Frontend Application: React-based dashboard for faculty approvals and administrative configuration.
• Backend Framework: Asynchronous FastAPI endpoints ensuring high-performance I/O for database operations.
• Notification Engine: Integrated automated email and SMS alerts for status changes.

Impact

Deployed via Docker containers on AWS with rolling update strategies, this SaaS product is currently utilized by 3 institutions, processing over 500+ requests per month with zero data bleed incidents.
