Aerospace engineering deals with designing and building machines that fly. It is one of the newest branches of engineering and began in the 19th century with the first experiments in powered flight. As technology progressed, two specialties emerged; aeronautical engineering, which involves designing aircraft such as powered lighter-than-air craft, gliders, fixed-wing airplanes and jets, autogiros, and helicopters; and astronautical engineering, which focuses on the design and development of spacecraft.

Biomedical engineering has recently emerged as its own study, as compared to many other engineering fields. Such an evolution is common as a new field transition from being an interdisciplinary specialization among already-established fields, to being considered a field in itself. Much of the work in biomedical engineering consists of research and development, spanning a broad array of subfields

Reverse engineering is a term mechanical engineering, is used to summarize the process of reconstructing an existing object. When designing an object from scratch, an engineer will draw up a design specification and produce drawings from which the item is constructed.

With reverse engineering, the design engineer starts with the final product and works through the design process in the opposite direction to arrive at the product design specification. During the process, vital information about the design concept and manufacturing methods is discovered.

Software engineering is defined as a process of analyzing user requirements and then designing, building, and testing software application which will satisfy those requirements. As it is a detailed study of engineering to the design, development and maintenance of software.

Freelance Electrical engineer is someone who designs and develops new electrical systems solves problems and tests equipment. They study and apply the physics and mathematics of electricity, electromagnetism and electronics to both large and small scale systems to process information and transmit energy. They work with all kinds of electronic devices, from the smallest pocket devices to large supercomputers.

Freelancer Telecom Engineering is one of those fields that have witnessed rapid advancement in recent years, it`s the backbone of mobile landscape, deploying voice, data, graphics and video at ever-increasing speeds and in a growing number of ways. And now wireless communication and satellite distribution are becoming increasingly dominant. Specialists in telecommunications engineering are needed to keep up with this ever-changing fast-paced industry.

Freelance network engineering let us first know what Network engineers are?
sometimes referred to as computer network architects, design, build, and operate computer network hardware, software, and servers. Although these engineers mainly plan networks, they might also perform job tasks like deciding which types of hardware are needed to support a network, designing the layout for data communication networks, and determining what types of security the network needs.

The demand on freelancing  has witnessed a great increase during the past years, as it increased by about 115% since 2005. 

due to freedom and flexibility it provides compared to traditional jobs. Freelance is no longer just a temporary option. 60% of independents say that they chose self-employment with their will, not because they did not find another option
