What I'm looking for

I’m looking to lead technical sales and business development where I can grow distributor channels, manage territory performance, and deliver customer-focused welding solutions that improve profitability and market share.

I’m a Mechanical Engineer and MBA graduate with extensive experience leading technical sales and business development across welding, manufacturing, construction, and industrial markets. I consistently exceed revenue targets by pairing consultative selling with deep product and application knowledge.

As Country Manager | Senior Business Development Manager at LINCOLN ELECTRIC, I directed national sales operations generating more than $4M annually. I built and expanded distributor partnerships, set budgets and pricing strategies, and used Salesforce CRM for forecasting and opportunity management—delivering approximately 20% year-over-year revenue growth.

Earlier, as Sales Manager | Technical Solutions Specialist at DISOL & ASOCIADOS, I managed business development across industrial, manufacturing, and construction markets. I prepared technical proposals and quotations, coordinated suppliers and engineering teams for project execution, and strengthened customer relationships through training, demonstrations, and solution-based selling.
