Work Preference
Summary
I am a motivated professional with experience in teaching, customer service, retail, and hospitality, now transitioning into remote sales. I taught English in South Korea, where I developed strong communication, cultural awareness, and the ability to tailor messages to diverse audiences. Certified with a 120‑Hour Premier TEFL/TESOL qualification, I gained expertise in lesson planning, classroom management, and adapting instruction for diverse proficiency levels. My customer‑facing roles at Uniqlo, House of Fraser, and Pizza Express strengthened my skills in relationship building, problem‑solving, and delivering excellent service in fast‑paced environments. I hold a BA in Business Management and am currently advancing my skills through Empathic Conversational Closing (ECS) training, preparing to excel in consultative, client‑focused sales opportunities.
