👨‍💻 About Me

"Architecting high-performance, real-time web applications, custom compilers, and deterministic multiplayer game engines with clean code."

I'm Ali Haggag, a Software Engineer & CS Student focused on System Design, Performance Optimization, and Security Hardening. I specialize in building complex backends, custom language parsers, and low-latency real-time synchronization layers.

🌟 Featured Engineering Builds

  • 🤖 Logic Arena — Competitive Robot Battle Simulator

    • Compiler & Sandbox: Engineered AliScript v2.2 (Lexer → AST parser) running inside a secure server-side sandbox with strict execution limits.
    • Real-time Sync: Built a 20 TPS physics engine with client-side state interpolation and delta compression (<50ms latency).
    • Tech Stack: Next.js 16, NestJS 11, React Three Fiber (Three.js), Socket.io, Redis, PostgreSQL, Prisma, Docker.

  • 🚀 Flurry Super App — Real-time Social Super App

    • Communication: Established WebRTC P2P media connections with custom Socket.io signaling servers (<50ms call latency).
    • UX & AI: Implemented an offline-first PWA architecture with Workbox Service Workers and integrated Gemini AI for group summaries.
    • Tech Stack: WebRTC, Socket.io, Gemini AI, PWA, React, MongoDB, i18next.
