Graduation project / senior thesis

Ain Shams University

An anonymous civic whistleblowing platform with cryptographic privacy guarantees. A graduation project built around one question: how do you make speaking up safer?

• Architected a four-layer trust-zone system: public internet → privacy proxy (DMZ) → internal backend → custom proof-of-authority blockchain.
• Built a privacy proxy that strips identifying headers and PII, manages anonymous sessions via Redis, and enforces sliding-window rate limits.
• Uploaded anonymous evidence to IPFS/Pinata with CIDs committed on-chain; encrypted identified complaints with AES-256-GCM in PostgreSQL and private Cloudflare R2 storage.
• Applied AI content filtering before any database or blockchain write.
• Implemented 184 unit/route-layer tests and 24 integration tests, plus Prometheus and Grafana observability with alerting.

B2B SaaS startup venture

Proprietary · In development

An all-in-one content operations platform for digital agencies, connecting briefs, creative iterations, internal reviews, and client approvals. Currently in development.

• Architected a multi-tenant content operations engine with logically isolated client portals, dedicated team dashboards, and secure asset workspaces.
• Engineered a state-machine flow for the full asset lifecycle: brief → design iteration → multi-stage internal review → client approval.
• Integrated AI-driven campaign planning alongside version-controlled iteration trackers for graphic and text assets.
• Designed decoupled publishing queues interfacing with social network graph webhooks for Meta, X, LinkedIn, TikTok, and YouTube.

InnovEgypt startup · ITIDA / TIEC

Cairo, Egypt

An OBD-II hardware and software module connecting real-time vehicle diagnostics, collision telemetry, and B2B insurance integration.

• Designed the architecture connecting an OBD-II hardware module to a mobile app for vehicle health checks, fault diagnostics, and emergency alerts.
• Engineered a black-box logging mechanism to securely store impact telemetry, diagnostic trouble codes, and velocity vectors upon collision detection.
• Integrated continuous dashcam capture with event-triggered snapshot isolation during erratic driving or telemetry anomalies.
• Structured a B2B model bundling telemetry cloud services with insurance products; awarded Certificate of Acknowledgement C0505S25T0677.
