What I'm looking for

I'm seeking a challenging engineering position where I can use my skills and knowledge to help successfully complete assigned tasks.

At DATAMAKER GHANA LIMITED, I worked on data annotation and labeling, including bounding boxes, polylines, polygons, and segmentation.

I also worked with 3D segmentation and point cloud data (PCD) on project tasks.

At EMCO QATAR (ENGINEERING AND MAINTENANCE COMPANY), I worked as an Electrical Technician/Electrician on planned preventive and daily maintenance. My work included air handling units, central battery systems, and UPS systems.

At DUFIL GHANA (INDOMIE NOODLE GHANA) and CARGILL GHANA LIMITED, I worked on electrical maintenance and installation, including motors, variable frequency drives, and instrumentation. I also created and filled work schedules in Maximo at CARGILL GHANA LIMITED.
