My Work Experience

Where I've interned and worked during my career.

Philippine Institute of Volcanology and Seismology | Mar 2025 - May 2025

Intern

Tested and retrained the PhaseNet deep learning model on Philippine seismic data to evaluate its performance on local earthquake events. Processed 1,325 earthquakes to assess its accuracy and potential for improving automated seismic phase picking. - Designed and implemented an ETL pipeline to process over 1,000 seismic files, enhancing data preprocessing efficiency. - Built local automation scripts in Python to scrape metadata, match waveforms, and convert data into structured CSV/NPZ formats. - Added error-checking and logging to handle file mismatches, broken links, and parsing issues, improving pipeline stability. - Contributed independently with mentorship to production-level ML workflows for earthquake waveform detection. - Trained and validated PhaseNet on regional seismic datasets (Abra 2022, Southern Leyte), verifying P- and S-wave prediction accuracy.
