About

Electrical Engineer working in the renewable energy space, currently focused on the operations and maintenance of off-grid solar PV and battery energy storage systems. I handle day-to-day plant monitoring, fault diagnosis, and equipment coordination on a 4MW Solar PV + 5.5MWh BESS facility — from resolving inverter, PCS, and BESS faults to leading recommissioning activities, SOC calibration, and direct collaboration with OEM R&D and Field Service Engineers.I'm interested in the growing distributed energy resources space and looking to contribute to teams pushing renewable energy adoption forward.
