Sinnie L.

Experienced Content Writer, Editor and Social Media Strategist

As a bilingual (English/Mandarin) content writer, editor and content marketing strategist, I help businesses and entrepreneurs capture attention, build trust and convert readers into loyal customers through compelling storytelling and strategies that convert. My approach is simple: storytelling + strategy = growth. I combine sharp, audience-focused writing with data-backed social media/SEO tactics to make sure your brand stands out in crowded feeds. Every piece I create is backed by thorough research and tailored to your brand’s voice, so you get content that not only informs but also inspires action. With a background in sociology and marketing, I bring unique insights into human behaviour and market trends, making me especially effective at writing on: - Social and environmental/sustainability issues - Marketing and promotional materials - Entrepreneurship and business strategy - Education and career advice - Lifestyle, such as food, health & wellness and gardening tips What I can deliver: - Social media strategy, planning and copywriting - Website content that attracts and converts - Blog articles that showcase thought leadership - Email campaigns & newsletters that drive engagement - Press releases & company profiles with impact - Business proposals & reports that persuade - Personal statements that stand out in applications I also offer professional editing and proofreading, built on years of experience as a book editor at John Wiley & Sons, and trusted by publishers like HarperCollins. Most recently, I was invited to work as an AI trainer on a variety of projects for major AI clients like Scale AI and Populii on data annotation and rating work, improving AI responses in the simplified Chinese language and comparing different AI models to determine which is better in terms of fulfilment, factuality, helpfulness, safety and presentation. If you’re looking for a partner to help you: ✅ Build an authentic online voice ✅ Turn content into leads and sales ✅ Create a social media presence that actually drives business results and builds your network ✅ Finetune your content, web copy or manuscript ✅ Improve AI-generated responses Send me a message or invite, and we can discuss how to bring your brand’s story to life.
