I’m a creative, user-centered web developer with 8 years of experience in Customer Operations (CX, CS and Customer Success). I’ve led the end-to-end design and implementation of customer interaction systems, as well as developed web portals for various industries and small to medium-sized businesses. I’ve worked with international organizations such as PayPal and currently work as a Senior CX Analyst at Linde PLC, managing and improving CX systems in Northern and Central Latin America. I genuinely believe we are here to connect, create and share meaningful experiences, and that belief guides the way I work.
