Mariam's Data Science Portfolio

I am data scientist with a passion for solving real-world problems using machine learning and data-driven insights, contributing to a range of projects that have made a significant impact. I have over 6 years of experience leading end-to-end data science projects and building production-ready predictive models in technology/software, retail, and CPG. Details are in my resume.

Education

  • πŸŽ“ I hold Master of Science in Applied Mathematics from Toronto Metropolitan University, with my thesis focus at the intersection of Network Science and Machine Learning.

  • πŸŽ“ I also hold an Honours Bachelor of Science in Mathematics, with minors in Statistics & Geographic Information Science, from the University of Toronto, which I completed in April 2023.

  • πŸŽ“ In addition, I previously started a Bachelor of Business Administration (BBA) from the Schulich School of Business at York University, which I departed in 2017.

  • 🌐 I am an Expert in Python (pandas, NumPy, scikit-learn, matplotlib) for data science and machine learning, and Intermediate in SQL (able to manipulate and analyze complex, large-scale datasets).

Projects

Here are some of the projects I've worked on:

πŸ“Š Simpson's Paradox Detection Function

  • Developed a Python function to detect instances of Simpson's Paradox in datasets. Git GitHub stars GitHub forks

πŸ“š DOSS Learning Toolkit for Undergrads in Statistical Sciences at UofT

  • Contributed to a learning toolkit for undergraduate students in statistical sciences at the University of Toronto. RepoGitHub stars GitHub forks

πŸ“š Experience (Resume+Git) Chatbot

  • Developed a RAG chatbot that answers questions about my resume & Git portfolio using OpenAI's GPT, FAISS, and Streamlit UI. Repo

πŸ“š Arxiv Recommendation System

  • Developed a recommendation system for arXiv research papers using NLP. Repo

πŸ“ˆ Stock Portfolio Optimization

  • Developed a stock portfolio optimization tool with visualization capabilities and risk-return criteria selection. RepoGitHub stars GitHub forks

✍️ Tutorial Worksheets

I used to post worksheets and slides from my tutorials/labs.
