🚀 Featured Projects

🦽 SANAD - Autonomous Wheelchair Backend

🎯 Graduation Project | Node.js WebSockets REST APIs Robotics Jest

A mission-critical backend gateway that exposes an autonomous wheelchair's robotics systems via modern web APIs, enabling remote control and real-time telemetry for individuals with mobility challenges.

Technical Achievements:

  • 🏗️ Hardware-Agnostic Architecture — Decoupled API layer from device implementations for maximum extensibility
  • ⚡ 30% Latency Reduction — Optimized communication protocol from JSON to BSON in rosbridge layer
  • ✅ Production-Ready — Comprehensive test suite covering REST endpoints and WebSocket connections
  • 🔄 Real-Time Communication — Bidirectional WebSocket implementation for live sensor data streaming

Impact: Bridging the gap between complex robotics systems and accessible web interfaces.

💼 Job Finder Platform

🔗 View Repository | TypeScript PostgreSQL Express JWT Sequelize

Enterprise-grade job board platform with sophisticated authentication and role-based access control, designed for real-world recruitment workflows.

Technical Highlights:

  • 🔐 Secure Authentication — JWT implementation with refresh token rotation and RBAC for three user roles
  • 🗄️ Optimized Data Layer — Normalized PostgreSQL schema with strategic indexing for query performance
  • 👥 Multi-Role System — Separate workflows for job seekers, employers, and platform administrators
  • 🛡️ Security First — Token rotation mechanism to minimize session hijacking and privilege escalation risks

Impact: Production-ready platform architecture supporting the full job search lifecycle.

🔬 OPST Research Lab Website

⚡ Performance Optimization | Next.js Static Generation CMS Integration GitHub Actions

Modernized a university research laboratory's web presence, transforming it from a slow SSR application into a lightning-fast static site while maintaining CMS flexibility.

Technical Solutions:

  • 📊 60% Faster Load Times — Migrated to static generation with smart client-side data fetching
  • 🔧 CMS Adapter Layer — Built abstraction layer enabling future CMS migrations without app changes
  • 🤖 Automated Pipeline — CI/CD workflow with static build validation and preview deployments
  • 📈 Serving 500+ MAU — Eliminated runtime server dependencies for better reliability

Impact: Dramatically improved user experience while reducing operational complexity.
