At Data Driven Lab, I provide customer support through HelpDesk and LiveChat, primarily in English, Portuguese, and Spanish. I use Jira to track requests and follow up on customer issues.

I previously worked at Hurb Technologies S.A. as a Back Office Assistant — Customer Experience, handling complex customer cases. I reviewed customer histories, coordinated with internal teams, and followed cases through to resolution using Zendesk and Zoho Desk.

Before that, I worked as a Trilingual Customer Service Consultant — Customer Success, supporting customers across chat, phone, email, and WhatsApp in Portuguese, English, and Spanish. I also followed up on complaints through Reclame Aqui and Consumidor.gov.br.

I studied System Analysis and Development at Cândido Mendes University and completed technical high school in Digital Game Programming at Colégio Estadual José Leite Lopes - NAVE. My studies covered game development and languages including C#, JavaScript, HTML5, CSS, and Java.
