Dear Hiring Manager,

I am writing to express my interest in a data science role within your organization. I am a recent graduate from the Faculty of Computer and Data Science at Alexandria University, where I earned my Bachelor’s degree with a CGPA of 3.3. My academic and practical experiences have equipped me with a solid foundation in artificial intelligence, statistics, data analysis, and data engineering.

During my studies, I developed strong analytical skills through coursework in regression analysis, convex optimization, multivariate analysis, data warehousing, and social network analysis. I have applied this knowledge in several projects, including:

RAG-Based AI Chatbot: Built a fully offline chatbot using local Large Language Models (LLMs) for text generation and embedding, combined with ChromaDB for vector search. The system included OCR capabilities to handle both Arabic and English PDFs.

Real Estate Price Prediction: Developed a regression model to estimate housing prices based on geographic and structural features.

Smart Home System: Designed and implemented a real-time monitoring system using ESP32 and IoT sensors for fire, gas, and intrusion detection, integrated with cloud storage and mobile app control.

Web Scraping & File Parsing: Created a data extraction pipeline using BeautifulSoup and file wrangling techniques to transform unstructured web data into clean datasets.

File System Simulation: Built a simulated file system in Python using a tree structure to mimic storage, permissions, and file operations.

I also completed a rigorous training program through the WorldQuant University Applied Data Science Lab, where I worked on eight intensive projects involving a wide range of data science techniques. This included time-series modeling (ARMA, GARCH), supervised/unsupervised learning (logistic regression, decision trees, k-means clustering), A/B testing, ETL pipelines, and dashboard development.

My professional experience includes internships at:

Alexandria Petroleum Company – Focused on software development and systems optimization.

Egyptian Petrochemical Company – Gained knowledge in database development and management.

Sidi Kerir Petrochemicals – Learned principles of network security and secure communications.

In addition, I volunteered with HackerRank's Academic Committee, contributing to educational content and supporting community learning initiatives.

Skills & Tools
Programming: Python, Java, R

Data Handling: SQL, NoSQL, MongoDB, SQLite, Snowflake

Big Data & Engineering: PySpark, Kafka, Docker, ETL

Visualization: Excel, Power BI, Matplotlib, Seaborn

Machine Learning: Scikit-learn, XGBoost, Clustering, Regression

APIs: RESTful API Design & Integration

Platforms: Linux, Git, Cloud Services

I am eager to bring my passion for data and problem-solving to your team and contribute to your organization's data-driven decision-making. I would be honored to discuss how my skills and projects align with your business goals.

Thank you for considering my application. I look forward to the opportunity to speak with you.

Sincerely,
Zyad Ashraf Hafez Gaber
