§ 01 — Selected work

Six
projects,
built end to end.

Each shipped solo across the entire stack — architecture, backend, frontend, infrastructure, and design.

VetoCore

Multi-Agent AI Orchestration

Architect & Full-Stack · SaaS vetoai-frontend.vercel.app ↗

Describe software and a roster of specialist AI agents (PM → Database → Backend/Frontend → Security → QA) builds it through a phased pipeline, streaming their work into a live console. Web, Windows desktop, and an installable PWA on one account.

Authenticated LLM proxy streaming Groq / OpenRouter / Gemini over SSE, metering every token into per-user usage & quotas.
JWT auth (argon2), AES-256-GCM encrypted provider keys, role-based user + admin dashboards.
In-browser live preview of generated apps, QA-rollback guardrail, MongoDB persistence, unit-tested core.

All Deadly World

MMO Server Ecosystem

Systems Engineer · C# / .NET deadlyworld.online ↗

A complete multiplayer game backend and operations stack: a real-time C#/.NET game server, a separate authentication server, a WPF launcher / patcher, and a PHP web portal with payments — ~325K lines across ~12,000 files.

Real-time TCP socket engine — 451 game classes, 150+ packet types, 40+ live tournament modes, A* bot pathfinding, map-threaded simulation.
Custom cryptography (Diffie-Hellman, CAST-5, Tiger hash, key-rotating cipher) and a "GShield" anti-cheat with HWID bans, memory/process scanning, Discord alerts.
PHP + MySQL portal (100+ tables) with Binance / e-wallet payments, voting rewards, live rankings, and WhatsApp admin notifications.

EDU

Educational Media Viewer — Desktop + Mobile

Solo · Python (PyQt6) & Flutter github.com/EDU ↗ EDU-Android ↗

A media viewer for educators and live-streamers — scan a folder and present images, video, PDF, and live websites in one window, with a drawing overlay and a stream queue. Built twice from scratch: a PyQt6 desktop app and a Flutter Android port. Bilingual EN/AR (RTL).

Desktop (PyQt6) — image pan / zoom / rotate, video player with speed control, PDF viewer with in-document word search, in-app web browser with bookmarks, recursive folder scanner, drawing overlay (pen / eraser, undo / redo), stream queue with auto-play, session restore. Shipped Windows release.
Android (Flutter / Dart) — mobile port with PDF, video, web view, a drawing toolbar, persistence, a Material 3 theme, and full RTL Arabic localization.
Resizable, session-restoring layout that remembers your last folder, queue, and language — built solo across both platforms.

Kryptonex

AI Startup Builder — SaaS Platform

Founder & Full-Stack · Next.js / TypeScript frontend-phi-ivory-65.vercel.app ↗

A multi-tenant SaaS platform that turns one prompt into a launched startup — AI-generated websites, mobile apps, ad campaigns, and marketing media, wrapped in a token-metered billing system and a bilingual (EN/AR, RTL) dashboard.

Custom design system — dark, high-contrast UI with layered 3D depth cards, animated aurora backgrounds, and WCAG-AA-checked contrast.
Token-based billing & usage metering per plan tier, with a project dashboard, domains, hosted sites, and admin panels.
Zustand state, Framer Motion micro-interactions, full i18n (English / Arabic RTL), deployed on Vercel.

Mazag

Multi-Tenant Food Delivery Platform

Architect & Full-Stack · Django mazag-production.up.railway.app ↗

A multi-tenant delivery platform (schema-per-franchise) connecting restaurants, home cooks, street vendors, drivers, and customers — with SSO auth, geolocation-aware ordering, wallets, and a full operations backend.

django-tenants schema-per-franchise multi-tenancy with a shared Keycloak realm and per-franchise clients (SSO across web + admin).
PostGIS-backed geolocation for orders and delivery zones; Celery + Redis for async tasks, notifications, and scheduled jobs.
Wallets & Paymob payments, promotions, subscriptions, live chat, and a customized Django Unfold admin with per-role dashboards (platform / franchise / driver / business).

Borhan

Multi-Tenant Learning OS · Web, Mobile & API

Architect & Full-Stack · NestJS, Next.js & Flutter borhan-phi.vercel.app ↗

One record from the centre door to the month-end books: QR attendance, parent notifications, protected video courses, auto-graded assessments, and Egyptian payment rails — three clients on one API, fully bilingual English/Arabic with RTL.

Tenant isolation enforced per database query, not in the UI — a cross-tenant read returns not found rather than forbidden, so the resource's existence is never disclosed.
Every payment rail funnels through one settlement service: a conditional PENDING → COMPLETED flip means concurrent webhooks, manual approvals and cash entries can never double-fulfil an enrolment.
Egyptian rails with no webhook (Vodafone/Orange/Etisalat Cash, InstaPay) settle by human review — receipts bound to the tenant, the reference unique-indexed against double settlement, and the reviewer recorded on the row.
Lesson video served via HMAC-signed URLs bound to the viewer and expiring in minutes; uploads are magic-byte verified before they reach an admin's browser.
Bilingual by construction — the Arabic catalogue is type-checked against English, so an untranslated key fails the build instead of leaking into a screen.

§ 04 — About

An engineer
who ships the
whole thing.

I like owning a product from the protocol up — game servers holding real-time state for thousands of entities, token-metered AI pipelines, auth hardened with modern crypto, and the dashboards and landing pages on top of all of it.

Beyond the three flagship projects, I maintain 32 open-source projects spanning C, C#, Python, Dart, TypeScript, React, and C++ — CLI tools, TUI frameworks, HTTP servers, security utilities, AI pipelines, and more. I move fast without skipping the boring-but-important parts — tests, CI, encryption at rest, rate limits, and clean UX.

“I'm just as happy debugging a packet cipher as I am tuning a CSS grid.”

I build bilingual (English / Arabic, RTL) interfaces, and I'm open to full-stack, backend, AI-platform, and systems roles — remote or contract.
