Isaac Molefe

An energetic, hard-working and responsible Millwright/Electrician with strong communication skills. I am a self-starter who performs effectively both independently and in a team, and I remain calm and productive under pressure. I bring an innovative and analytical approach to fault-finding, a constant willingness to learn, and a proven ability to read and analyse electrical and mechanical drawings.
