The Narrative

From Friction to Flow

Every project begins with a bottleneck. Here is how we diagnosed the root cause and engineered the cure.

The Challenge

Certificates needed a structured review process before becoming publicly available to ensure accuracy.
Public verification endpoints required strict protection against automated abuse and excessive queries.
Administrators lacked visibility into overall system health, database size, and disk utilization.
Compliance required maintaining a reliable audit trail for all user actions and a 2-year data retention policy.

The Solution

Engineered a multi-stage workflow where certificates (JPEG/PDF) enter a pending queue for approver review.
Implemented robust rate limiting on the public search page to securely support heavy traffic without degradation.
Built a centralized Admin Dashboard for real-time monitoring of server status, DB size, and activity logs.
Configured automated nightly backups with daily verification reports to guarantee data integrity and availability.

System Architecture

Core Features

A technical breakdown of the key modules and engineering decisions behind this platform.

Approval Workflow

Uploaders submit JPEG or PDF certificates to a pending queue. Approvers can review, approve, or reject submissions with feedback.

Django / State Machine Logic

Public Search & Verification

Allows public users to verify certificates instantly using the certificate number and issuing date.

React / PostgreSQL

Anti-Abuse Rate Limiting

Middleware restricting the public search endpoint to prevent excessive automated queries and scraping.

Django Ratelimit

System Health Dashboard

Provides system administrators with real-time tracking of server status, database size, and disk utilization.

Python / React

Role-Based Access Control

Strict permissions separating Uploaders, Approvers, and System Administrators to ensure operational security.

Django Auth / JWT

High Test Coverage & Stability

The entire web application is backed by exceptionally high test coverage. This rigorous testing approach makes the platform highly stable and significantly less prone to runtime errors in production.
