Professional Summary
Full-Stack & Mobile Engineer with a track record of architecting and shipping production-grade from first
principles. Specialized
in offline-first mobile applications (Flutter/Dart 3 with SQLite Master, zero-latency optimistic UI
synchronization, and Clean Architecture), distributed cloud backends (Appwrite 6-database architecture,
Spring Boot, Supabase, Cloudflare R2 direct-to-edge storage), and autonomous AI agent workflows (Google
Antigravity 2.0, Claude models: Opus 4.8 / 5 / 5.5 & Sonnet, Model Context Protocol MCP servers, and ARTEMIS
testing). Passionate about high-fidelity UX, rock-solid security protocols, and owning the complete product
lifecycle from architecture to production release.
VENTURES & PRODUCTION ENGINEERING
Offline-first multi-tenant residential operating system & governance engine
- Architected an enterprise offline-first SQLite Master engine with zero-latency
optimistic UI synchronization, background LWW sync, 48h DLQ TTL, 2-min offline guards, deterministic
pre-sync role reconciliation, and automated purges across 24+ tables upon role demotion.
- Reduced backend database reads by ~88% via offline-first caching and cursor-based
delta sync (server-side
$updatedAt high-water marks, soft-delete
tombstones).
- Decoupled community messaging into a polymorphic dual engine: Appwrite Realtime
WebSockets for premium estates and Telegram MTProto (TDLib) with bounded 80-message memory windowing and
scroll offset anchoring.
- Built a 4-tier perimeter security suite with sub-50ms offline HMAC-signed QR pass
validation, NFC patrol checkpoint logging, automated overstay alerts, and unified incident
dispatch.
- Engineered direct-to-edge media storage via Cloudflare R2 with progressive RAM
eviction; eliminated
build_runner via native Dart 3 sealed classes;
integrated Shorebird OTA for instantaneous code pushes.
AI-powered Chrome Extension · Autonomous browser workflow engine (
Chrome Web
Store · MV3)
- Engineered a 6-provider AI orchestration layer with automatic waterfall failover
across Groq (Llama 3.3 70B), Google Gemini 2.0 Flash, OpenRouter, Local Ollama, and on-device Gemini
Nano as a zero-failure fallback.
- Architected an intelligent browser automation extension utilizing CDP (Chrome DevTools
Protocol) with organic event dispatching, contextual form filling, and resilient multi-step
DOM workflows.
- Architected a dual-storage split (flat Firestore schema with 1:1 SQL mapping +
chrome.storage.local for credentials) and shipped 7 Chrome Web Store
releases with PII-scrubbed New Relic telemetry.
Academic Capstone Project
Computer Science Diploma Graduation Project (Cairo University) · Full-stack clinic
platform
- Built a full-stack medical services platform as the Computer Science Diploma graduation
project at Cairo University — RESTful Spring Boot backend with strict Clean Architecture
domain boundaries.
- Implemented Spring Security & JWT with 3-role RBAC (Doctor, Patient, Clinic Admin),
stateless session management, and secure password hashing.
- Designed relational MySQL schemas with B-tree indexing for high-concurrency
appointment scheduling, patient queues, and electronic health records.
- Engineered a responsive React web client with real-time appointment status workflows
and interactive doctor filtering.
