reducing unnecessary downtime while ensuring overall data quality.
• Procured reliable and cost-effective equipment essential to operations, implementing process as new standard
practice.
• Coordinated internal meetings and collaborated on final presentations, guaranteeing customer satisfaction to
establish recurring business.
Senior Technical Professional and Fiber Optic Analyst, Houston, TX 2014 — 2015

2. Planned, performed, and led DTS and DAS StimWatch, and other fiber optic monitoring jobs conducting data
interpretation and analysis both real-time and post-job. Technical expert and advisor of Fiber Optic monitoring
operations, from data acquisition to data analysis in U.S. Southern District.
• Improved data acquisition methods, ensuring data quality, decreasing down-time and additional man hours
during field operations and data post-processing.
• Created and revised existing procedures, enhancing operational performance and customer satisfaction.
• Served as Senior Analyst and Operations Lead for a 2MM+ 4-well Fiber Optic Stimwatch Project monitoring all 4
wells simultaneously during Frac operations with both DTS and DAS technology, successfully completing largest
