Professional Summary
AI/ML Intern with 1+ years of experience building machine learning models and Python applications; skilled in TensorFlow, supervised learning, data preprocessing, and software development workflows. Seeking an internship or entry-level role to contribute to model development, data pipelines, and production-ready ML solutions while continuing to learn and expand practical experience.
Technical Skills
Work Experience
- Designed and implemented a Secret Code Generator using Caesar cipher in Python to demonstrate encryption/decryption logic and modular code structure.
- Built an Expense Tracker with file-based persistent storage, implementing CRUD operations and input validation using Python file handling and OOP.
- Developed a command-line Personal To-Do List application applying OOP design patterns to manage tasks, priorities and persistence across sessions.
- Structured code into reusable modules and classes to separate business logic from I/O, improving maintainability and reusability across utilities.
- Documented functionality and usage with README-style instructions and sample usage examples to simplify handoff and review.
- Used Git for version control and followed iterative development workflows during the internship, committing changes and managing code history.
- Trained a multi-class animal image classification model using TensorFlow, implementing data pipelines for image loading, preprocessing and batching.
- Applied image augmentation and preprocessing techniques to expand training data and improve model robustness and generalization.
- Evaluated model performance using standard metrics and confusion analysis to iterate on model architecture and preprocessing steps.
- Built a movie recommendation system using collaborative filtering techniques to model user-item interactions and generate ranked suggestions.
- Enhanced recommendations with basic NLP feature extraction (TF-IDF) on movie metadata to incorporate content signals alongside collaborative signals.
- Logged experiments and documented model configurations, training procedures and evaluation results to support reproducibility.
- Completed hands-on supervised learning modules covering data collection, labeling and preprocessing workflows using Jupyter and Colab notebooks.
- Implemented feature engineering and data cleaning techniques to prepare datasets for model training and validated transformations with sample data.
- Explored model selection and hyperparameter tuning approaches to compare performance across candidate algorithms.
- Applied cross-validation and evaluation metrics to assess model stability and generalization on held-out datasets.
- Documented end-to-end experiments and produced reproducible notebooks that demonstrated model training, evaluation and interpretation.
- Gained practical exposure to the full ML lifecycle including dataset preparation, model training, evaluation and iteration best practices.
Projects
- Trained an image classification model to distinguish multiple animal categories using labeled image datasets and supervised learning workflows.
- Applied preprocessing and augmentation (resizing, normalization, flips) to increase dataset variability and improve model generalization.
- Iterated on model architecture and evaluated using validation splits to refine performance and reduce overfitting.
- Built a recommendation engine employing collaborative filtering to suggest movies based on user-item interactions and preference data.
- Extracted content features from movie descriptions using basic NLP (TF-IDF) to augment collaborative signals and improve suggestion relevance.
- Evaluated recommendation relevance with holdout tests and refined feature integration to improve rank ordering of suggestions.
