Google Photos Takeout Merger

High-performance metadata pipeline built with Spring Boot and multi-threaded processing to restore Google Photos metadata at scale.

  • Built a high-performance metadata pipeline using Spring Boot with a thread-pooled engine processing 50GB+ photo libraries; implemented dynamic regex JSON suffix matching for truncated filenames with sub-millisecond O(1) in-memory directory lookups.
  • Engineered platform-agnostic system integration supporting Windows, macOS, and Linux with native OS file dialogs; automated standalone executable packaging via CI/CD requiring zero runtime installations for users.

Drowsiness Detection System

Real-time facial tracking and eye movement analysis system to detect drowsiness and prevent vehicular accidents.

  • Engineered a real-time video processing pipeline using OpenCV and dlib, applying Eye Aspect Ratio (EAR) signal analysis to detect drowsiness with 95% accuracy.
  • Designed threshold-based event detection logic with low-latency audio-visual alert dispatch, achieving sub-28ms frame latency for real-time responsiveness.
