Featured Projects
Real-world applications showcasing backend engineering expertise
Wasla — Real-Time Egyptian Sign Language & Emotion Recognition
Backend & ML Engineer
Graduation project: a multi-threaded real-time computer vision pipeline (MediaPipe + Keras) recognizing Egyptian Sign Language and emotions, served through a desktop app and a FastAPI/WebSocket service.
Key Contributions & Impact
- ▸Designed a multi-threaded inference pipeline with bounded, drop-oldest queues to decouple camera capture latency from model inference
- ▸Exposed a stable predict_frame() API contract (label, confidence, emotion) so a separate team could integrate without breaking changes
- ▸Served the model over FastAPI + WebSocket: decoded base64 JPEG frames, ran inference, streamed back predictions with latency metrics
- ▸Evaluated 3 model architectures (baseline MLP, augmented MLP, Bi-LSTM) with ablation tables and confusion matrices to justify the production choice
Architecture Decision
Chose a bounded-queue threading model over synchronous inference to keep the UI responsive under variable camera and model latency
Technologies Used
Python
MediaPipe
TensorFlow/Keras
OpenCV
FastAPI
WebSocket
FixMate — Vehicle Service Booking Platform
Backend Engineer
Clean architecture-based RESTful API for vehicle service booking, managing service requests, status tracking, and mechanic assignment.
Key Contributions & Impact
- ▸Architected with Clean Architecture (Domain, Application, Infrastructure, API layers) for independently testable concerns
- ▸Built end-to-end booking workflows with JWT-based authentication and role-based authorization
- ▸Containerized with Docker and documented via Swagger/OpenAPI
Architecture Decision
Adopted Clean Architecture to ensure testability, maintainability, and independence from frameworks
Technologies Used
ASP.NET Core 8
C#
EF Core
Clean Architecture
Docker
JWT

GenzApp — Authentication Module
Backend Developer (auth module)
Freelance engagement: designed and implemented the authentication module for a client application.
Key Contributions & Impact
- ▸Implemented OAuth-based authentication flows for secure third-party sign-in
- ▸Delivered the module as an independent, integrable unit within the client's existing stack
Architecture Decision
Scoped strictly to the auth boundary so the module could ship without coupling to the client's product roadmap
Technologies Used
OAuth
JWT
