Tsz Yin CHOI

• Engineered and deployed 25+ scalable AI solutions (e.g., AI in customer service, n8n workflow automation, OpenClaw and internal management systems with AI) that reduced manual operational tasks by an average of 30% • Built and delivered tailored AI training programs for 5+ cross-functional team members (Engineering, Operation, Marketing). This led to a 35% increase in team productivity and the independent implementation of AI tools by non-technical staff. • Conducted continuous research on emerging frameworks (Skills, , A2A Protocols, RAG, MCP, agentic systems), structuring 40+ detailed prompts to solve complex business challenges. • Explored and validated use cases for generative AI in multimedia creation. This reduced prototype asset generation time from days to hours and identified 3+ high-potential opportunities for future product development.

• Developed and deployed 10+ AI agents in n8n workflow automation system through prompt engineering to autonomously handle customer service inquiries. This automation resolved 80% of routine customer queries without human intervention • Architected and led the full SDLC for a customer-facing web application using React/Vite, integrating OpenData APIs and an iFrame for seamless access to company tools • Developed an internal system using React/Vite to streamline operations, featuring a centralized repository for customer service template messages and a one-on-one reservation scheduling system for clients • Leveraged GenAI tools (e.g., Google Veo3) to produce a pipeline of marketing assets. This included generating 30+ unique images/audio clips and producing a 2.5 minute startup story video with AI, which reduced traditional content production costs by ~HKD$7,000

• Provided year-round, tailored guidance to a dedicated caseload of 8+ fellow students, developing individualized study plans that connected them with university resources (tutoring, mental health services). • Supported key university initiatives by assisting in the execution of orientation events, including the Faculty Induction Talk, contributing to a smooth transition for over 330 incoming freshmen

• Spearheaded the end-to-end R&D of a Mixed Reality application by XRCC engine developed by Votanic. Engineered and user-tested 5+ novel interaction mechanics for virtual object manipulation and equipment handling • Translated complex technical research into accessible formats by designing posters and producing/editing 2+ demo videos. • Developed and instructed a 2 days comprehensive VR development curriculum for a cohort of 35+ high school students. Through hands-on XRCC engine programming and design sprints, 100% of students successfully built and deployed their first interactive VR environment.
