Message

At Telefónica Colombia, I supported agile teams across marketing, product development, data analytics, e-commerce, and logistics. I facilitated Scrum, Kanban, and SAFe practices, and contributed to products and services that improved delivery for customers.

As Project Manager for the FullStack BSS Digital Transformation Program, I coordinated the migration of fixed-line services to a new CRM platform. I managed a direct team of four, and testing during the migration reduced billing-related complaints to almost zero.

At Huawei Technologies Ltd., I managed application and software projects for telecommunications clients, including CLARO and ETB. Earlier, I delivered telecom software and network solutions across the CALA region, and at CVG EDELCA I led the restoration of microwave shelters and a helipad at Tepuy El Venado.
