About ME Resume

Currently Reading 📕 : Black Hat Graphql

My name is Mahmoud Elaraby, I graduated from Zagazig University, Faculty of Science, with a major in Mathematics and Computer Science. I am interested in software engineering, with a specific focus on security engineering, particularly web application security. I also enjoy studying mathematics and its relationship to computer science, especially analytical subjects. I am constantly learning about optimization and enjoy building simple, high-quality programs aimed at making life easier for people or addressing societal issues, contributing to a better life for them. I love blogging about what I learn or engaging in discussions and thinking through topics with others, as it helps me understand things more deeply.

Projects

Seizure Detector Flask | C/C++ | Flutter | ESP32 | Azure | GIT

Description

In epilepsy, approximately 67% of individuals respond well to medication, 7-8% to neurosurgery, while 25% face recurrent seizures with no effective treatment. To enhance care for this group, a user-friendly device (using a pulse sensor, ESP32, and an accelerometer) is proposed for automated seizure detection, aiming to reduce the burden of monitoring and accidents related to epilepsy.


Story of the project

This is my First-Term Graduation Project. Before it, I had no knowledge about IoT or mobile development. I began working on it before the deadline, completing it within 12 days despite routine problems at the college. This proved to be a significant disaster for me, prompting me to seek advice from everyone I knew. After some time, I discovered that I had a good foundation to complete this project within the deadline. During this period, I learned about the components I would use, such as the ESP32, MPU6050, and MAX30102. I delved into how to install them together and write code for their functionality. I gained insights into dual-core usage for reading data from the device and sending it to my cloud server. I also learned how to implement a fall detection algorithm and enhance it with heart rate monitoring to detect seizures. This process consumed a considerable amount of time, especially during exam periods, making me realize that I hadn't created the mobile application yet. The next day, I began learning how to create it using Flutter. I dedicated an entire day to work and learning, eventually creating a basic application that fetched data from my server, displayed it, and sent notifications to my phone when seizures occurred using Firebase Messaging and local notifications. This was sufficient for me. After that, I wrote a simple Python server to interact with different APIs, such as Twilio for sending SMS, Mailgun for sending emails, and Firebase Cloud Messaging for sending notifications to the phone if anything happened. Now, it was time for deployment. I deployed it using Microsoft Azure, Nginx, and Gunicorn, and everything worked fine before the deadline, earning me an excellent grade.





Thoth Chatbot Python | SQLite | Azure | FastAPI | Git

Description

Chatbot with inline keyboards designed to assist my colleagues in obtaining lecture notes, news, and any information related to our college.


Story of the project

The name Thoth is the name of the Egyptian god of knowledge. This is a side project I created during my second year at university. I developed it in response to the continuous requests from my colleagues for study resources and notes. The idea was to have a chatbot that could provide immediate answers to such requests. I collected lecture notes and data from my colleagues and built the bot. Within three days, it gained popularity, and other departments from my college requested to add materials for them. It was eventually used by more than 150 active users.





Supplier Management System Python | SQLite | PyQT | Git

Description

Desktop application to manage supplier operations for importers.


Story of the project

I built this application when I found that my friend, who works as an importer of laptops and computer kits, was facing challenges when a new shipment arrived. He struggled with managing orders, including tracking quantities, origins, remaining payments to suppliers, warehouse inventory, and more. I developed this project to assist him in efficiently tracking and organizing his orders.





Ecommerce And Book Management System APIs
Node.js | Express.js | Mongodb | Postgresql

Description

Simple APIs for e-commerce website and Book Managment System


Story of the project

I built these projects for educational purposes to practice Node.js, MongoDB, and PostgreSQL. I implemented CRUD operations, JWT authentication and authorization, forgot password functionality with email and SMS capabilities, and effective error handling





Crack Detection
Python | YOLOv7 | Machine learning

Description

Machine learning Freelance Project to detect the cracks in the roads


Story of the project

This was my first freelance machine learning project. I created it for a professor (as i guess) in machine learning, utilizing YOLOv7. The experience helped me learn extensively by studying relevant papers before implementing the project





Publications

(G′/G)-expansion method and its application to Mikhailov-Novikov-Wang equation

This publication is for my second-term graduation research. Till now, my professor hasn't confirmed its public release. However, feel free to request access to it.
This article presents an application of the (G′/G)- expansion method to the Mikhailov-Novikov-Wang equation, a non-evolutionary partial differential equation that has garnered extensive research attention due to its fundamental significance in various branches of physics and mathematics. The (G′/G)-expansion method is a powerful mathematical tool for finding exact solutions for nonlinear partial differential equations. In this article, we describe the main steps of the (G′/G)- expansion method and apply it to the Mikhailov-Novikov- Wang equation. We obtain new exact solutions for this complex system, demonstrating the effectiveness of the (G′/G)-expansion method in solving challenging problems in physics and mathematics. This article highlights the importance of nonlinear partial differential equations in modeling complex physical phenomena and underscores the value of mathematical tools such as the (G′/G)-expansion method in advancing our understanding of these systems.
