Cover image for Alhamdulillah for showcasing the deployment
Alhamdulillah for showcasing the deployment of my Bachelor Project at the German University in Cairo: an Adaptive Computational Thinking Education Platform powered by Machine Learning. The core objective was to engineer a platform that doesn't just serve educational content, but adapts to how a student learns and performs in real-time. To achieve this, I bridged ML with a containerized full-stack architecture. Here is a technical breakdown of the system: Core ML Capabilities * Dynamic Learning Style Adaptation: Engineered Bayesian Networks utilizing pgmpy to continuously infer and update a student's preference between verbal and visual learning. * Adaptive Exercise Difficulty: Implemented a Bayesian model that dynamically serves easy, medium, or hard exercises based on real-time solving time taken. * Struggling Detection: Integrated an LSTM model that monitors coding attempts to provide a guide when a student is supposedly detected to be struggling. System Architecture * Node.js Orchestrator: Serves as the central hub for business logic, database operations, secure user authentication. * Python FastAPI Server: Dedicated to hosting the ML services and managing secure, isolated code execution environments. * React Client: Provides a clean, interactive UI for lectures and active coding exercises. Cloud & DevOps Infrastructure * Azure Container Registry (ACR): Acts as the centralized hub for the deployment pipeline, securely managing the Docker images for both backend services. * Azure Container Apps: Hosts the Node.js orchestrator as a dedicated single instance. * DigitalOcean Droplets: Hosts the FastAPI server, specifically utilizing a Docker-out-of-Docker architecture to safely spawn and isolate containers strictly for executing user-submitted code. #SoftwareEngineering (https://www.linkedin.com/search/results/all/?keywords=%23softwareengineering&origin=HASH_TAG_FROM_FEED) #MachineLearning (https://www.linkedin.com/search/results/all/?keywords=%23machinelearning&origin=HASH_TAG_FROM_FEED) #FullStack (https://www.linkedin.com/search/results/all/?keywords=%23fullstack&origin=HASH_TAG_FROM_FEED) #DevOps (https://www.linkedin.com/search/results/all/?keywords=%23devops&origin=HASH_TAG_FROM_FEED) #React (https://www.linkedin.com/search/results/all/?keywords=%23react&origin=HASH_TAG_FROM_FEED) #Nodejs (https://www.linkedin.com/search/results/all/?keywords=%23nodejs&origin=HASH_TAG_FROM_FEED) #Python (https://www.linkedin.com/search/results/all/?keywords=%23python&origin=HASH_TAG_FROM_FEED) #FastAPI (https://www.linkedin.com/search/results/all/?keywords=%23fastapi&origin=HASH_TAG_FROM_FEED)#SystemArchitecture (https://www.linkedin.com/search/results/all/?keywords=%23systemarchitecture&origin=HASH_TAG_FROM_FEED) #GermanUniversityInCairo (https://www.linkedin.com/search/results/all/?keywords=%23germanuniversityincairo&origin=HASH_TAG_FROM_FEED)#GUC (https://www.linkedin.com/search/results/all/?keywords=%23guc&origin=HASH_TAG_FROM_FEED)

Cover image for Pizza Delivery Co. React Router (Data
Pizza Delivery Co. React Router (Data API): Implemented the createBrowserRouter using Loaders and Actions. This shifts data fetching to the routing layer, eliminating fetch-on-render waterfalls and layout jank. Redux: Managed Global UI state and persistent data using Redux, ensuring a single source of truth and predictable state transitions. Clean Architecture: Combined the power of Router Loaders for initial data fetching with Redux for long-term state management, creating a seamless and snappy user experience.

The-State (a dashboard for a class of my university) I built The-State specifically for students (my colleagues) to access lecture PDFs and take related quizzes, all in one convenient platform. On the admin side, the dashboard allows full control over the class: tracking student numbers and names, managing file uploads, blocking or controlling access, and monitoring Firebase storage and quota limits. The goal was to make the learning process smoother for my class while giving me an easy way to manage everything efficiently.

Cover image for This is a small application
This is a small application using React.JS and Node.JS that organizes books by dividing them into three categories: Read, Want to Read Later, and Currently Reading. You can also search for and add new books. The application is a search engine connected to an API point. You enter the book's name, and if it's available, it will appear. You can then add the book to one of the three categories, where it will be displayed. Books can be easily moved between categories.
