At Neoenergia Coelba, I managed distribution network maintenance and expansion across 13 municipalities. I reduced TMAE from 1,200 minutes toward a 940-minute target and kept DEC within the regulatory range.

Previously, at Grupo Equatorial Energia, I coordinated maintenance across 38 municipalities, where DEC fell from 2.1 hours to 0.89 hours in August 2024. At Grupo Energisa, I supervised network maintenance and construction, including a 12 km project completed without customer outages or accidents.
