vetoai-frontend.vercel.app · SolidJS · Electron · Hono · MongoDB · TypeScript · JWT/AES-GCM · SSE · PWA

• Built an authenticated LLM proxy streaming Groq/OpenRouter/Gemini over SSE, metering every token into per-user usage & quotas; web, Windows desktop, and installable PWA on one account.
• JWT auth (argon2), AES-256-GCM encrypted provider keys, role-based user + admin dashboards, in-browser live preview with QA-rollback guardrail, and unit-tested core.

deadlyworld.online · C# / .NET · WPF · TCP Sockets · Cryptography · Anti-Cheat · PHP · MySQL · Node.js

• Real-time TCP socket game server — 451 game classes, 150+ packet types, 40+ tournament modes, A* pathfinding, map-threaded simulation (~325K LOC / ~12K files).
• Custom cryptography (Diffie-Hellman, CAST-5, Tiger hash, key-rotating cipher) + GShield anti-cheat (HWID bans, memory/process scanning, Discord alerts); PHP/MySQL portal with Binance/e-wallet payments & WhatsApp admin notifications.

frontend-phi-ivory-65.vercel.app · Next.js 14 · TypeScript · Tailwind CSS · Zustand · Framer Motion · RTL i18n · Vercel

• Multi-tenant SaaS platform that turns a single prompt into a launched startup — AI-generated websites, mobile apps, ad campaigns, and marketing media.
• Token-metered billing with per-plan usage quotas, a project/domains/hosted-sites dashboard, and a custom dark UI design system with 3D-depth cards and animated motion; fully bilingual EN/AR (RTL).

mazag-production.up.railway.app · Django 5 · DRF · django-tenants · PostGIS · Celery · Redis · Keycloak/OIDC · Channels

• Schema-per-franchise multi-tenant platform connecting restaurants, home cooks, street vendors, drivers, and customers, with a shared Keycloak realm for SSO across web and admin.
• PostGIS-backed geolocation for orders/delivery zones, Celery+Redis async tasks, wallets and Paymob payments, promotions, subscriptions, live chat, and a role-based Django Unfold admin (platform/franchise/driver/business dashboards).

borhan-phi.vercel.app · NestJS · Next.js 16 · Flutter · PostgreSQL/Prisma · Socket.IO · LiveKit · S3/R2 · Paymob · Fawry

• Three clients on one API (Next.js portal, Flutter app, REST/WS backend) covering QR attendance, groups & timetabling, protected video courses, auto-graded assessments, live classes, billing and wallets — for schools, academies and independent teachers.
• Tenant isolation enforced at every database query rather than in the UI, with cross-tenant reads answering not found instead of forbidden so a resource's existence is never disclosed; role-scoped access across admin, instructor, secretary, student and parent.
• Single settlement path for every payment rail — a conditional PENDING→COMPLETED transition makes concurrent webhooks, manual approvals and cash entries incapable of double-fulfilling an enrolment; Egyptian mobile-wallet and InstaPay transfers settle through human review with tenant-bound receipts and a recorded reviewer.
• Lesson video delivered over HMAC-signed, viewer-bound URLs expiring in minutes, with magic-byte verification on upload; argon2id credentials and single-use, hash-stored reset tokens.
• Bilingual English/Arabic with RTL across web and mobile, the Arabic catalogue type-checked against English so an untranslated key fails the build rather than reaching a user.

github.com/MrHassan2027/EDU · PyQt6 · Flutter / Dart · Syncfusion · video_player
