I have worked in both voice and non‑voice roles and have proven ability to manage high‑volume customer interactions under pressure.
I am adaptable, a fast learner, and comfortable working in teams or independently; I was recognized as an exchange employee intern through YMCA and completed roles that combined technical troubleshooting with customer retention and sales outcomes.
