En tant que fondateur de MachineMFG, j'ai consacré plus d'une décennie de ma carrière à l'industrie métallurgique. Ma vaste expérience m'a permis de devenir un expert dans les domaines de la fabrication de tôles, de l'usinage, de l'ingénierie mécanique et des machines-outils pour les métaux. Je suis constamment en train de réfléchir, de lire et d'écrire sur ces sujets, m'efforçant constamment de rester à la pointe de mon domaine. Laissez mes connaissances et mon expertise être un atout pour votre entreprise.
