What I'm looking for

I seek roles combining ESL instruction and content/marketing in collaborative, efficiency-driven teams that use digital media and provide opportunities to design curriculum and grow professionally.

I bring a global perspective and a premium on excellence, with years teaching ESL, IELTS, TOEFL and Business English to learners from Japan, China, Vietnam, Taiwan, Russia and beyond. I prioritize efficiency and effectiveness in both classroom instruction and content production.

As a content writer and marketing officer, I have written press releases, email campaigns, social media captions, website copy, and training materials; I have also managed Facebook and Instagram accounts and designed marketing collaterals using Canva. I combine instructional skill with practical marketing and multimedia production experience.

I have led teams and projects, supported corporate training initiatives, and developed learning materials and communications that drive engagement. I am motivated by opportunities to blend teaching, content strategy, and digital media to deliver measurable results.
