A production-facing portfolio that transforms class capstones into live, reviewable AI workflows across data science, machine learning, and deep learning.
Built From Scratch — Full-Stack AI Portfolio
Every layer of this site was designed and engineered custom — from the server infrastructure and PHP application layer to the front-end styling, AI model hosting, and CI/CD-style deploy pipeline. There is no CMS, no page builder, and no third-party template.

- PHP 8.x via FastCGI
- SFTP + SSH deploy pipeline
- Laravel Herd (local dev)
Back-End
- PHP — custom MVC-style routing
- JSON-driven result feeds
- Dynamic includes architecture
- Per-capstone content modules
Front-End & Branding
- Bootstrap 5 (custom-configured)
- Hand-authored CSS design system
- Custom FB logo + monogram
- Responsive across all breakpoints
AI & ML Layer
- Python / TensorFlow / Keras
- TensorFlow.js (in-browser inference)
- Teachable Machine integration
- Jupyter notebooks (Colab-ready)
Data & Storage
- Git LFS for large datasets
- CSV / image / JSON datasets
- GitHub as source-of-truth
- Exported model artefacts on-server
Deploy & DevOps
- PowerShell build + zip pipeline
- Posh-SSH SFTP upload
- SSH unzip-to-docroot on server
- Git versioned every release
Notebooks & Science
- pandas, NumPy, scikit-learn
- Matplotlib / Seaborn
- EfficientNet, ResNet50, LSTM
- K-Means, PCA, Market Basket
Toolchain
- VS Code + GitHub Copilot
- Google Colab (GPU training)
- Python venv (3.12, local CPU)
- PowerShell 7 + Posh-SSH
Training Highlights
Each capstone runs a real training pipeline — raw data, cleaned splits, model fit, evaluation, and exported artefacts. Below are the standout projects.
3-Class Face Mask Detector
EfficientNetB0 and ResNet50 trained on 12,000+ images across three classes: with_mask, without_mask, mask_worn_incorrect. Model exported to TensorFlow.js and Teachable Machine — both run live in-browser.
Bike Rental Demand Forecasting
Regression pipeline on UCI Bike Sharing dataset: feature engineering on weather/season/time variables, Random Forest + Linear Regression comparison, RMSE and R² evaluation.
Adult Census Income Classifier
Binary classification on the UCI Adult Census dataset: encode + scale, train Decision Tree / Logistic Regression / Random Forest, ROC-AUC comparison, confusion matrix analysis.
Mall Customer Segmentation
K-Means clustering on spending-score and income features. Elbow-method optimal-k selection, PCA 2D visualisation of cluster centroids, actionable segment labels.
Market Basket Analysis
Apriori algorithm on 7,500 retail transactions. Frequent itemset mining, confidence/lift-ranked association rules, actionable product-pairing insights.
MNIST Digit Recognition (CNN)
Convolutional Neural Network on 70,000 handwritten digits. Multiple conv/pool/dense configurations compared, training curves logged, test accuracy benchmarked against baseline MLP.
Datasets Hosted on GitHub
Browse repo ↗All datasets are version-controlled directly in the GitHub repo alongside their notebooks. Image data uses Git LFS — notebook clones pull full binary data automatically, no manual download step.
