A tech graduate is someone who has completed a degree in a technology-related field, such as engineering. An ENGINEER is a professional who designs, builds, and maintains machines, structures, and other technological systems. Engineers use mathematics, physics, and other sciences to solve problems and create new technologies. They also develop plans and specifications for the construction of buildings, roads, and other infrastructure. Engineers must have a strong understanding of the principles of engineering and be able to apply them to real-world situations.
