I am working as a civil engineer at civil and structural engineering consultant at skudai, johor bahru. Usually, I will design and draft the drawing myself. So, minor amendment will be no problem for me to draft in any drawing. Should u have any inquiries pls do no hesitate to contact me. My working day only from Sunday to Thursday and I'll be off working on Friday and Saturday. I am glad to hear feedback from u soon. Tq.
