I've worked in two companies; one of them was Octopus Outsourcing.I've enrolled in the Select Home Warranty account I was responsible for handling the customers and giving them the best solution such as filing the customer claim or sending him a technician and following up with him until the problem is fixed.

And the second one is the Cold Calling Role in Skyline BPO in a real estate Campaign, it was a really interesting role and I've learned a lot in this position. I handled more than 500 calls per day It gave me a lot of skills such as the negotiation skills and how we can convince the customer to sell his property and I last month I was one of the top achievers at the company, I truly love this role and I think I can contribute my skills in your company to develop my English skills and grow up

In a professional way.

I Built My Own Private AI Infrastructure and Monitor all my own Traffic

In an era where data privacy is paramount and cloud dependencies are rising, I decided to take control. I built a completely local, self-hosted AI environment that runs powerful language models (LLMs) like DeepSeek-R1, Llama 3.2, and Phi3 – all without sending a single prompt to the cloud. But that’s not all:

I integrated real-time network monitoring to watch over my home lab, detect anomalies, and stay ahead of potential threats.

? أهداف المشروع :

1. تشغيل ذكاء اصطناعي محلي (Ollama + Open WebUI) بأمان

2. مراقبة الشبكة المنزلية (ntopng)

3. تأمين الخدمات بجدار ناري (UFW)

? Why This Project Matters

This wasn’t just about running AI locally, It was about building, securing, and monitoring a real infrastructure.

What I Built

-Local LLMs using Ollama

-Containerized interface with Docker

-Hardened host on Ubuntu 24.04

-Strict firewall policies using UFW

-Full traffic visibility via ntopng

-Web interface deployed through Open WebUI (localhost only)

1 - الخصوصية أولاً (Privacy First)

بياناتك تبقى على جهازك.

لا External APIs

لا Cloud Dependencies.

لا تسريبات.

عند تشغيل نماذج مثل Ollama محليًا، أنت تملك السيطرة الكاملة على البيانات والمعالجة.

2- أمن عملي (Hands-On Security)

بدلاً من قراءة نظريات عن:

Firewall Hardening

Port Restriction

Network Isolation

UFW وقواعد صارمة للتحكم في المنافذ ومصادر الاتصال

3- مهارات متعددة في مشروع واحد

المشروع يجمع بين:

Linux Administration عبر Ubuntu

Containerization باستخدام Docker

Network Segmentation

Firewall Policy Design

AI Model Deployment

API Integration

4- الرؤية والتحكم (Visibility)

باستخدام ntopng يمكنك:

رؤية حركة المرور لحظيًا

اكتشاف الأجهزة الجديدة

تحليل التدفقات (Flows)

مراقبة البروتوكولات

اكتشاف محاولات المسح (Port Scans)

الرؤية = سيطرة.

بدون Monitoring، لا يوجد أمن حقيقي.

? أبرز النقاط الأمنية

✅ (Least Privilege)

✅ Service Binding Control

✅ Firewall Enforcement

✅ Docker Network Isolation

✅ Continuous Monitoring

✅ Reduced Attack Surface

هذا ليس مجرد تشغيل خدمات…

بل تصميم بيئة مقاومة للهجوم.

?? لماذا يجب على مطوري الويب الاهتمام؟

لأنك هنا لا تستخدم API جاهز فقط…

أنت تدير:

نظام التشغيل

الحاويات

محرك النماذج

واجهة الاستخدام

قواعد الشبكة

طبقة الحماية

وذلك مع REST API من Ollama لبناء تطبيقات مخصصة بالكامل.

كما يمكنك:

إضافة نماذج جديدة

دمج Frontend خاص بك

تعريض الخدمة بشكل آمن عبر VPN

تحويل المشروع إلى Internal AI Platform
