Amândio Fernandes began his journey in the shipbuilding industry, later passing through the metalworking industry, where he gained expertise, experience and a business vision, which, in 1999, he put at the service of his own company, AJF, and went on to serve other areas of activity.

In our yard we have an “Acetylene and Oxygen distribution station, Project A.L.” whose debit is made to Linave’s internal distribution network.
Despite the degree of automation of this installation, its maintenance is also assured by the firm AJF (Representative of AL), with high professionalism in the Technical and Availability component, for many years until the present date.

For over 15 years, I have worked with AJF on numerous projects at industrial and medical level.
