DIATADMIN — CLIENT-FACING ADMINISTRATIVE SYSTEM

End-to-End Delivery & Requirement Analysis

Context

Delivered a custom administrative system for DIAT, a multi-branch technical institute, by working directly with non-technical stakeholders to translate academic, financial, and operational workflows into a maintainable full-stack solution. Owned backend APIs, data modeling, authentication, and VPS deployment alongside the frontend, focusing on clarity, reliability, and cost-aware engineering rather than infrastructure scale while delivering the system from requirements through production. Implemented a QR-based student identity feature that allows secure public access to student profiles, academic records, and fee payment statements via scanned IDs.

Problem Statement

DIAT relied on spreadsheets and disconnected tools to manage admissions, academics, finances, and inventory across branches, leading to inconsistent data, duplicated effort, and limited operational visibility.

System Flow / Design Decisions

  • Identified branch isolation as a core business requirement and implemented branch-scoped data access and permissions within a single shared deployment
  • Translated informal administrative workflows into explicit system rules for admissions, attendance, fee handling, expenses, and inventory movement
  • Structured backend modules around real organizational domains (Academic, Finance, Inventory) to align the system with departmental responsibilities
  • Centralized authentication and role-based access control to simplify user management across branches
  • Designed a QR-based student identity mechanism to enable controlled public access to student academic and financial information without requiring full authentication
  • Recognized financial data loss as a critical operational risk and implemented a lightweight, zero-cost automated backup flow using existing cloud storage
  • Chose a simple VPS-based deployment model to minimize operational overhead and ensure the system could be maintained without dedicated infrastructure staff

Impact & Outcomes

  • Used daily by administrators across 4 active branches
  • Replaced fragmented manual and spreadsheet-driven workflows with a unified system
  • Enabled QR-based student identity verification for quick access to academic and fee information
  • Improved reliability and auditability of academic and financial operations
  • Delivered a maintainable solution aligned with tight budget and operational constraints
