Data Science Portfolio - Martins Nnamchi

Hello there!

Welcome to my data science playground! I'm a data enthusiast with a knack for turning numbers into stories and patterns into insights. With a flair for machine learning and a love for all things data, I'm here to explore, innovate, and, most importantly, have fun with data! Dive in to see how I blend analytical rigor with a dash of creativity to solve real-world problems!

Accurate Celebrity Identification Using Prompt Engineering and Google Gemini 2.0 LLM API

This project demonstrates the application of Large Language Models, specifically Google's Gemini 2.0 Flash, to perform celebrity identification in images using Python. An upload interface is provided using IPyWidgets to test the functionality.

Predictive Modeling of Wind-Energy Generation with FLASK deployment: Time Series and Regression Analyses

In this project, I explored time series and regression for renewable-energy forcasting. I developed XGBOOST-trained ML models to predict the amount of wind energy that can be generated over a period. I deployed the model using FLASK, creating an interactive web app that delivers real-time energy predictions. This project kickstarts my learning in time series analysis and end-to-end model development/deployment.

SpaceX Launch Analysis and Landing Predictions

In this project, I predict if the Falcon 9 first stage will land successfully. The predictions will help determine launch costs and aid operational planning. I implement Dash/Plotly Interactive Dashboards, REST APIs, Web scraping, SQL queries, Data Wrangling/Preprocessing, EDA, and ML pipeline development. Full PDF Report

Credit Card Fraud Detection

In this project, I built models that predict if a financial transaction is fraudulent or not, aiming to enhance credit card security. I model the task as a binary classification problem and implement SVM and DT models using both Scikit-Learn and Snap ML. Linkedin Report Article

Rainfall Prediction in Australia

In this project, I employ supervised classification models to predict rainfall in Australia. Four different classification models were implemented: K Nearest Neighbors, Decision Tree, Logistic Regression, and Support Vector Machine. The Logistic Regression model exhibited the best performance, with a prediction accuracy of 84%.

Micro Projects

• Data Collection & Vizualization

  • Stock Data Extraction and Visualization Using REST APIs and Webscraping: In this project, I extract and vizualize stock data with the yfinance API and Web scraping.
  • Car Dealership's Inventory Management System: This Python program simulates a car dealership's inventory management system. The system aims to model cars and their attributes accurately.
  • Chicago Dataset SQL Querying: In this file, I attempt to comprehensively understand three Chicago datasets using SQL queries and %sql magic.
