Company Intranet System

Internal operations · Communication · Assessments · Admin tools

A full-scale company intranet built from scratch to run an entire organisation in one place. It covers internal communication (company feed, newsletters, messaging), day-to-day operations (support tickets, requisitions, vehicle bookings, front desk, cash receipts), HR touchpoints (profiles, birthdays, anniversaries, team directory), an admin portal for managing employees, documents, newsletters and more, plus a full assessment engine used both for internal staff training and for external candidates applying to join. Powered by a C# Web API backend with a custom HTML / CSS / JavaScript frontend.

// Case Study

Problem, Solution & Outcome

Built to replace fragmented tools and unify the company onto one platform

The Problem

Internal communication was scattered across emails, WhatsApp, and shared drives. Support requests, vehicle bookings, finance requisitions and training assessments all lived in different tools. Onboarding, profile management and HR moments like birthdays had no central home, and there was no single place admins could manage employees, documents, newsletters or company-wide tooling.

The Solution

A custom intranet with a modular C# Web API backend powering a clean HTML / CSS / JavaScript frontend. One platform covers communication, all operational requests, an admin portal, HR moments, knowledge assessments, and quick links to every internal resource — secured with JWT and role-aware authorization.

The Outcome

Replaced multiple paid third-party tools, reduced operational cost, and centralized every internal workflow into one daily-driver platform used by 171+ employees. Reporting, audit trails, and admin oversight all improved significantly, and onboarding is now standardized through the same assessment engine.

// Knowledge Engine

Dual-Mode Assessment System

The same assessment engine powers internal staff training and external candidate screening — secured by two separate JWT authentication flows.

Internal Staff

Authenticated Employee Assessments

Internal users sign in to the intranet and take assessments tied directly to their employee profile. Their attempts, scores, pass/fail status, and history are persisted against their identity for HR, training, and audit purposes.

  • Standard intranet JWT session
  • Attempts linked to employee profile
  • Pre & post training scoring
  • Visible in HR reporting
  • Multi-day onboarding programmes
External Candidates

ID-Verified Public Assessments

External candidates applying to join don't have intranet logins. Instead they submit an ID number which mints a separate, scoped JWT used only for that assessment session. Their results are recorded for screening but are not tied to an employee profile.

  • Separate JWT issuance flow
  • ID number based identification
  • Scoped session-only tokens
  • Knowledge-screening only
  • Isolated from employee data
