About
My professional background includes many years in the commercial area - where I gained experience with customer relationship building, account management, teams management, hiring and training - but also a strong technical background as a Solutions Architect and a Software Engineer, with an extensive knowledge in frontend and backend development, APIs and complex systems integrations.
Currently as a Solutions Architect at Twilio for Latin America, which is a senior role within the pre-sales solutions engineer team, I drive customers to find the best solutions and architect their technical projects using our vast range of products. On top of this, I am also a member of the SE enablement team.
Nowadays, as part of the Communications BU, I'm engaged on strategic opportunities where clients require solutions with a higher technical complexity for the following products: E-mail API (Twilio Sendgrid), Messaging (Chatbots - including AI/Cognitive, SMS & WhatsApp APIs), Account Security (Twilio Verify & Lookup APIs), Voice (IVRs - including AI/Cognitive & Programmable Voice, SIP Interface, Elastic SIP Trunking APIs), Twilio Studio (No code platform used to create Twilio applications) and Twilios Serverless (Used to create event-driven microservices, integrate with 3rd party endpoints, and extend Twilio Studio flows with custom logic)
