Project Experience
Doctor Chat – AI Assistant for Medical Consultations
https://github.com/data-tamer2410/ds-doctor-chat
Tech Stack: TensorFlow, Transformers, Docker, Sreamlit, Pandas.
In this project, I developed an AI-powered chatbot that provides medical advice and recommendations.
The bot utilizes a fine-tuned GPT-2 model to generate responses in a structured dialogue format between
the patient and a virtual doctor. The application is built using Streamlit and deployed on a server, ensuring
seamless accessibility. The chatbot offers personalized health advice, making it an essential tool for quick
consultations and initial diagnostics.
Achievements: Fine-tuned the GPT-2 model to achieve high accuracy in generating medical advice,
reducing perplexity to 12.91. Implemented a rigorous fine-tuning process to tailor the responses specifically
to the medical domain, ensuring that the chatbot provides accurate, reliable, and contextually appropriate
answers. Built an intuitive and engaging front-end with Streamlit, allowing users to interact easily with the
bot and receive personalized advice.
Weather Forecast API
https://github.com/data-tamer2410/ds-weather-forecast
Tech Stack: Keras, FastAPI, Docker, Numpy, Pandas, Scikit-Learn, Matplotlib.
In this project, I developed an RNN-based API to forecast weather conditions for the next day using
historical data from the past 7 days. The API was containerized using Docker and deployed on a server,
enabling seamless integration and scalability. The endpoint is easily accessible via POST requests, making it
practical for real-world applications in weather monitoring or decision support systems.
Achievements: Designed and deployed an RNN model optimized for time-series weather data prediction.
Built a FastAPI backend, packaged it in Docker, and deployed it on Render. Developed an interface that
accepts 7 days of weather data and returns precise forecasts, including the probability of rainfall.
Implemented scaling and reshaping mechanisms to prepare complex weather datasets for accurate model
inference.
