Projects

PhotoFit AI

App Store Play Store

AI-powered mobile fitness app that generates personalized workouts based on equipment and goals.

I designed, built, and shipped this application from the ground up, handling all aspects of development:

  • Product direction and feature decisions
  • Mobile app architecture using React Native and Expo Router
  • Backend systems with Firebase Auth, Firestore, and Cloud Functions
  • AI workflows for personalized workout generation
  • Subscription payments and lifecycle management with RevenueCat
  • Analytics, crash reporting, and production monitoring
  • App Store and Play Store review, compliance, and launch

Building PhotoFit AI shifted my perspective from feature-focused development to system thinking: reliability, scalability, failure modes, and user trust.

AI Model Catalog CLI

GitHub

Command-line tool for evaluating the trustworthiness of open-source AI/ML models.

The AI Model Catalog CLI assesses models from GitHub and Hugging Face by calculating a weighted NetScore across eight dimensions—from documentation and licensing to dataset quality and maintainability—helping teams make informed decisions about model adoption.

My Role

  • Backend Developer & API Integrator
  • Built scalable Python modules for GitHub and Hugging Face API integration
  • Implemented LLM-enhanced scoring using the Purdue GenAI Studio API
  • Added parallelized metric computation and auto-grader NDJSON output
  • Contributed to CI/CD setup, debug logging, and configuration

Key Features

  • Dual-source model analysis (GitHub & Hugging Face)
  • 8-dimensional trustworthiness scoring system
  • LLM-powered README and metadata evaluation
  • Parallel metric processing with built-in rate limiting
  • Auto-grader and NDJSON output for reproducible scoring
Tech Stack: Python, GitHub API, Hugging Face API, Purdue GenAI Studio API, Pytest, Pre-commit, CI/CD

Casino Simulator

GitHub

Object-oriented casino simulation demonstrating clean architecture and extensibility.

  • Designed 40+ OOP classes including Blackjack, Poker, and other casino games
  • Scalable architecture allowing new games to be added with minimal refactoring
  • Emphasizes encapsulation, design patterns, and modular design principles

IBM ML Certificate Projects

GitHub

Applied machine learning concepts through IBM's AI Engineering specialization.

  • Completed 20+ ML projects using Python, NumPy, and Pandas
  • Implemented supervised and unsupervised models, evaluation metrics, and ML pipelines
