What I'm looking for

I am seeking customer-focused IT roles where I can apply systems administration, field support, and multilingual communication to improve operations, reduce costs, and build client loyalty.

I am a technology professional with over 30 years' experience in systems administration, field technical support, and commercial technology roles across Portugal and Latin America. I focus on customer satisfaction, loyalty, and practical solutions that reduce costs and improve operations.

My career includes senior IT systems analyst roles, field technician and freelance IT analyst work, and specialist support positions where I provided multilingual interpretation (Portuguese, Spanish, English) and technical guidance for end users and commercial teams. I have led projects to update and implement equipment with energy and cost savings in mind.

I bring hands-on expertise installing software and hardware, network administration, warranty and repair management, project support, and customer-facing technical training. I am adaptable, customer-focused, and experienced working across cultures and languages to deliver reliable IT solutions.
