The Student Desk

From lecture halls to production code

Saleem is a Computer Science undergraduate in his final year, with hands-on experience developing secure web applications, REST APIs, and enterprise database systems.

His work spans the full stack, from ASP.NET Core and Node.js services on the backend, to React interfaces on the front end, backed by MongoDB, MySQL, and Oracle SQL.

He's currently applying that foundation inside a real enterprise environment as an IT Intern, while shipping independent projects that explore authentication, authorization, and, most recently, healthcare AI.

Four buildings, four problems solved

Tap a building to walk inside: challenge, solution, and the stack behind it.

BUILDING 01 · SECURITY

User Management API

A role-based API layer for managing users, permissions and sessions securely.

ASP.NET CoreJWTRBAC

GitHub ↗

ChallengeEnterprise clients needed fine-grained access control without slowing down every API call.

SolutionBuilt a token-based auth layer issuing short-lived JWTs with role claims, validated through custom middleware and cached permission lookups.

Key LearningsDesigning middleware pipelines in ASP.NET Core and structuring RBAC so new roles don't require a redeploy.

BUILDING 02 · SECURITY

SafeVault

A hardened authentication & authorization system built around secure coding practice.

AuthAuthorizationSecure Coding

GitHub ↗

ChallengeCommon auth implementations leak details through error messages and weak session handling.

SolutionImplemented hashed credential storage, uniform error responses, and session invalidation rules to close common attack paths.

Key LearningsHow small implementation details (timing, error verbosity, token scope) decide whether an auth system is actually secure.

BUILDING 03 · BUSINESS

Oracle APEX Solutions

Low-code enterprise apps: an Intern Management System and a Shop Management System.

Oracle APEXOracle SQL

GitHub ↗

ChallengeTwo organizations needed working internal tools fast, without a large dev team to maintain them.

SolutionDelivered an Intern Management System and a Shop Management System in Oracle APEX, with validated forms, reporting pages, and role-based views.

Key LearningsHow to model real business processes directly into declarative, low-code applications without losing data integrity.

BUILDING 04 · HEALTHCARE · FYP

Visual Jaundice

Final year project: AI-assisted neonatal jaundice detection from medical images.

AI / MLImage AnalysisHealthcare

GitHub ↗

ChallengeNeonatal jaundice often goes undetected early enough in low-resource settings without lab access.

SolutionBuilt an image-analysis pipeline that screens newborn skin images for jaundice indicators, aimed at early, low-cost detection.

Key LearningsBridging applied AI with a real clinical constraint: accuracy has to hold up outside a lab, on ordinary photos.
