I am skilled in knowledge-base strategy, chatbot automation, AI automation, root cause analysis, and cross-functional collaboration. I work closely with product and engineering teams to triage issues, identify bugs, and help improve customer onboarding and product experiences.

In my current role, I have maintained a 96% CSAT score while contributing to knowledge-base and automation improvements that reduced repetitive tickets by 45% and average response time by 35%.

I also bring experience in telesales, upselling, data entry, data analysis, quality assurance support, and sales-performance monitoring. I am comfortable using Excel, Google Sheets, basic SQL, Zapier, Jira, and Slack to support operational efficiency.

I am a native English speaker based in Lisbon, Portugal, with basic conversational Portuguese skills. I am focused on customer support and customer operations roles where I can combine technical troubleshooting, automation, and customer success expertise.
