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!

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.
