About

With over 15 years of experience in marketing, executive support, and office operations, I bring a versatile skill set and a strategic mindset to help businesses grow and run smoothly. As Marketing Manager at onActivity Limited, I lead the planning and execution of integrated marketing strategies, from digital campaigns to physical events like exhibitions and open houses. My role extends beyond marketing — I provide direct executive support to company directors, oversee administrative operations, manage vendor partnerships, and supervise the office accounts team to ensure accurate financial reporting. I’ve played a key role in supporting the company’s expansion into Southeast Asian markets, building strong relationships with local partners and aligning regional efforts with overall business goals. Whether it’s crafting compelling content for digital platforms, streamlining office processes, or mentoring junior staff, I’m passionate about creating impact through thoughtful leadership and effective communication. Earlier in my career, I gained valuable experience in customer service, franchise operations, and regional office setup during roles at Horspath Limited and Fitness First Hong Kong, which shaped my ability to manage complex logistics, support senior leadership, and work across departments.
