About

Professional summary

I am an Electrical Engineer with more than 15 years of experience in electric power distribution, line design, construction supervision, and power system planning in the Philippines.

I most recently led a six-member design and construction team and coordinated more than 13 line-construction contractors. I delivered over 100 distribution line projects annually, including 144 projects and 86.5 circuit kilometers of new lines in 2025.

My technical background includes medium-voltage distribution line design and staking, construction supervision up to 69 kV, substation layout, quality control, site safety inspections, contractor billing review, and project close-out documentation.

I have hands-on experience with power system analysis, including load flow, short-circuit, system-loss, and reliability studies. I have used these analyses to support capital investment planning, outage investigations, voltage complaint resolution, and regulatory reporting.

I also have practical industrial electrician experience involving troubleshooting, installation, maintenance, and repair of electrical wiring, control, and lighting systems. I am currently completing a Master of Business Management focused on Production and Operations Management.

I am preparing to relocate to Germany, where I expect to be authorized for employment from October 2026. I speak fluent English and Filipino, native Cebuano, and intermediate German at B1 level, which I am actively improving.
