At Accenture, I work on industrial projects in mining and oil & gas, analyzing processes and supporting cost optimization and supplier contract initiatives. I also monitor field activities and help teams define future-state solutions and process improvements.

As a Mid-Level Analyst at Accenture, I developed and implemented the PTS Center, reducing issuance time from about an hour to 17 minutes. I integrated data into a Power BI dashboard, prepared documentation, trained the team, and supported deployment across four industrial plants.

At GE Vernova, I developed and analyzed engineering documentation for automation systems, including communication with a Schneider M580 PLC. My experience also includes industrial network architecture, Excel VBA optimization solutions, and electrical installation projects using AutoCAD.
