Built platform to register and verify AI-generated images on the blockchain to combat misinformation. Used OpenAI API + Pinata (IPFS) + Solidity on Polygon blockchain to link images with smart contracts. Implemented detection layer to check if online images match known AI content.
Designed and implemented machine learning pipeline, from data loading and cleaning to feature engineering, model validation and evaluation. Benchmarked models including Linear, Ridge, Lasso, Random Forest, Polynomial, and XGBoost; tuned hyperparameters with GridSearchCV. Achieved top performance with XGBoost (R² = 0.868); reduced MAE and MSE by 35% compared to baseline models.
Clustered Brazilian stocks by price behavior using K-Means and GMM; validated with silhouette score. Reduced data with PCA for visualization; explained grouping of companies in business terms. Built end-to-end notebook pipeline with clear analysis and plots.
Performed customer segmentation analysis using unsupervised machine learning techniques. Applied K-Means clustering to identify distinct customer groups based on age, income, and spending behavior. Created detailed cluster profiles and visualizations to enable targeted marketing strategies and personalized customer experiences.
Built real-time event management system for Blockchain Rio 2025 conference to solve chaos of managing multi-stage blockchain events. Created comprehensive solution with real-time timeline across 14 stages, live status updates, organizer dashboard with cascade delay management, and mobile-first design for 40+ events and 8 conference stages.
Developed machine learning model for breast cancer prediction using clinical diagnostic features. Implemented comprehensive data preprocessing, feature engineering, and model evaluation pipeline. Applied various classification algorithms including logistic regression, SVM, and ensemble methods to achieve high accuracy in predicting malignant vs benign tumors for early detection assistance.
