Electrical Power Systems Engineer with strong hands-on experience in substation construction, electrical distribution networks, and rural electrification projects. Core expertise covers end-to-end execution of 11kV and 33kV systems, including design support, field supervision, commissioning, and final handover. I worked with Bangladesh Rural Electrification Board (BREB/REB) from 1996 to 2005, where I was involved in rural power infrastructure development and substation-related projects. Responsibilities included field survey, engineering design support, construction supervision, testing, energization, and project close-out activities. Key experience includes supervision of 11kV and 33kV distribution lines, pole installation, transformer placement, earthing systems, and network construction. I also contributed to 33/11kV substation works, including outdoor substation installation, equipment setup, and system integration for reliable operation. Engineering responsibilities included load surveys, topographical surveys, route selection, staking of distribution lines, preparation of Single Line Diagrams (SLD), as-built drawings, key maps, and detailed documentation. Also involved in feasibility studies, BOQ inputs, inspection activities, fault identification, troubleshooting, and preventive maintenance. I have strong field supervision experience working with contractors, technicians, and engineering teams to ensure safe execution, quality control, and timely project delivery. Throughout my career, I have been involved in the full lifecycle of electrical infrastructure projects—from planning and design to construction, commissioning, energization, and final handover. Although I have not yet worked directly under European electrical standards, I am highly adaptable to new regulatory frameworks and technical environments. I can quickly learn and align with European engineering practices when given the opportunity.
