My Engineering Evolution

From writing my first line of C++ to architecting autonomous AI agents with custom languages.

The Foundation

"I learned to think in code"

Started my B.Sc. in Computer Science & Artificial Intelligence at South Valley National University. Laid strong foundations in algorithmic thinking, object-oriented design, and relational databases.

View details

The Builder

"I learned to build for users"

Earned my Front-End Development Diploma and mastered the art of building responsive, interactive user interfaces. Adopted bilingual RTL/LTR patterns that would become a standard in all future projects.

The Engineer

"I learned to build systems"

Completed a Backend Internship at Web Masters. Engineered RESTful APIs, optimised MongoDB schemas, mastered JWT authentication, and shipped Blog Pro — a full CMS with 5-layer security.

The Architect

"I learned to build at scale"

Architected complex, offline-first systems. Shipped Flurry with WebRTC P2P calling and offline-first PWA sync. Launched CS Arena as a developer ecosystem. Built the Cybership carrier integration with domain-driven boundaries.

View details

The Inventor

"I built my own language"

Created Logic Arena — a competitive robot-programming platform with a custom DSL (AliScript), a 3D physics engine, cinematic arenas, and a 60-level campaign. Led the frontend of StudentHub in an 8-person Agile team.

The AI Pioneer

"I taught machines to think"

Building Scout — an autonomous AI job-application agent as my graduation project. A cognitive brain loop with ethical guardrails, worker-thread browser automation, and a 'Never Lie' claims verifier.

Scout Cognitive Brain Loop

Watch how Ali engineered Scout's crash-safe 5-stage cognitive architecture — main-thread reasoning with Playwright worker_threads isolation.

DOM Snapshot & Screening Question Extraction

Captures full DOM snapshot & extracts screening questions

EXECUTION STREAM

[DOM] Extracting screening form fields:
  - Question: "Years of experience with NestJS/Node.js?" -> TYPE: numeric
  - Question: "Are you willing to work hybrid in Cairo?" -> TYPE: boolean_radio

GUARD SPECSystem Guardrail

Playwright isolates page navigation in worker_threads, sending DOM trees over worker IPC without freezing the main LLM thread.

Hard Architectural Ethical Guardrails

Final Click RuleACTIVE

Requires explicit human approval before any application is submitted

Never Lie VerifierENFORCED

AliScript v2.4

A scripting language Ali engineered from scratch — a hand-written Lexer, recursive-descent AST parser, and a deterministic 2,000-ops/tick TLE quota evaluator — all running entirely in the browser, zero dependencies.
