Profile

I am a backend-oriented developer with a strong foundation in computer engineering and hands-on experience in building cloud-based and serverless systems.

I focus on developing efficient, maintainable, and scalable backends — from REST APIs and authentication systems to cloud functions and automation pipelines.

I enjoy working close to the infrastructure layer, understanding how data flows through a system, and designing reliable services that make everything else possible.

Education

Cairo University – Faculty of Engineering
B.E. in Computer Engineering
Fall 2020 – Fall 2025

  • Graduation Project: Inferex — built a context-aware Q&A system that processes screenshots, PDFs, and videos using a compressed LLM model.
  • Compressed an 8.5GB LLM model to 5GB using Huffman encoding and GPU-based decompression.
  • Fine-tuned an extractive QA model to improve performance on non-answerable questions by 5%.

Experience

Ejada Hybrid – Cloud Computing Intern

July 2024 – August 2024

  • Deployed a multi-tier book reservation platform on Google Cloud Platform (GCP).
  • Worked with services such as VMs, VPC, Cloud SQL, and block storage.
  • Gained practical understanding of Cloud Functions, BigQuery, IAM, GKE, and Cloud Run.

Farahy / TheWizard – Frontend Intern (Remote)

September 2023 – October 2023

  • Designed and implemented interactive dashboards and landing pages using React and Figma.
  • Collaborated with designers and backend developers to build functional, user-friendly web interfaces.

Projects

Serverless Image Processing Architecture (AWS)

  • Built a serverless infrastructure for image uploads and automatic thumbnail generation.
  • Used 2x AWS Lambda functions, API Gateway, and S3 buckets (one public, one private).
  • Created presigned URLs for uploads and automated processing on object creation events.
  • Managed IAM roles and permissions for Lambda and API Gateway integration.

Wireless-DFS – Distributed File System (Go)

  • Built a network-based file system using Go, designed to handle file uploads and downloads across distributed nodes.
  • Used gRPC for control communication and TCP for file transfer.
  • Implemented core services: MasterTracker (metadata management) and DataKeeper (file storage).
  • Added replication and heartbeat mechanisms for fault tolerance and reliability.
  • Handled hashing-based duplication prevention and dynamic port allocation for parallel transfers.

MatchMaker – Full-Stack Match Management Platform

  • Developed backend services in Go with REST APIs, JWT authentication, and role-based access.
  • Integrated WebSocket support for real-time match status updates.
  • Designed modular services for users, matches, teams, and stadiums.

Inferex – Context-Aware Question Answering System

  • Built a program that takes user context (screenshots, PDFs, videos) and answers questions from it.
  • Implemented LLM compression and fine-tuned extractive QA models.
