What I'm looking for

I’m looking for roles where I can deliver SLA power uptime, lead field/NOC-facing teams, and use RMS/KPI analysis plus RCA/PPM to prevent recurring faults—open to remote, hybrid, or on-site work.

I’m a telecom professional with 10+ years spanning core network engineering (RAN/OMC-R, 2G/3G) and telecom tower power infrastructure management across Nigeria and Ghana. I’ve led multi-disciplinary field operations across generator, rectifier, solar PV, and battery systems—built on second-level technical support, BTS/BSC/RNC integration, KPI/fault management, and software upgrades across Huawei, ZTE, and Alcatel-Lucent platforms.

In power systems, I focus on sustaining SLA-aligned performance through rigorous diesel and PPM management, RMS/KPI monitoring, RCA, and preventive action planning for recurring faults. I’ve managed tower portfolios (100–200+ sites), aiming for 99.9% power uptime, coordinating escalation workflows, and delivering technical documentation and EHS-compliant operations across regional field and NOC-facing teams.
