At Foxit, I lead the development and architecture design for the Asia-Pacific team, focusing on the development of an AI-driven PDF system. This system powers various AI functionalities for Foxit’s PDF readers, plugins, websites, and partner clients. These features include Named Entity Recognition (NER), table extraction, intelligent classification, and sensitive information redaction, all designed to enhance user experience and improve work efficiency. We developed iDox.ai, an AI-powered document compliance solution, which automates compliance processes to enhance data protection and simplify document management across industries, helping businesses meet regulatory requirements effectively. As the team lead, I am responsible for developing the AI engine’s APIs and collaborating closely with internal teams from requirement gathering to system design, ensuring efficient and effective solution delivery. I also contribute to writing code and designing systems to further optimize the solution’s performance. Through system design and architecture improvements, I successfully optimized resource utilization, achieving equal or even better performance, enhancing the platform’s efficiency to meet clients' compliance needs.

As part of Aotter’s backend development team, I was primarily responsible for building scalable services using technologies such as Kotlin, Vert.x, MongoDB, and Redis to implement reactive architectures. I worked closely with the frontend team to ensure comprehensive solutions were delivered. We streamlined our deployment process through Docker and Kubernetes, supporting an efficient CI/CD pipeline to ensure smooth and reliable product delivery. Our main product was an advertising system designed to handle large volumes of daily ad requests. It was engineered to manage high-traffic loads, helping businesses optimize their advertising strategies, effectively reach their target audience, and ensure a seamless user experience. Additionally, as an outsourcing partner, we participated in several client projects, including developing the ticketing system for 7-Eleven’s ibon platform and providing solutions for Gamania’s SSO and social media features. These solutions were tailored to meet clients’ specific needs and business objectives.

During this period, I contributed to the following key projects: - Customer Service Chatbot: Developed an intelligent customer service chatbot to enhance user interaction and support, significantly improving customer engagement and satisfaction. - User Personalization and Recommendation System: Designed and implemented a user profiling and recommendation system using data analytics and machine learning, providing a personalized user experience. - Intelligent Content Management System: Implemented an intelligent content management system to automate content creation and curation, streamlining workflows and improving efficiency. - User-Friendly Dashboards and Interfaces: Built and maintained user-friendly dashboards and interfaces, integrating complex datasets to enhance data visualization and accessibility. Our team was organized into small groups, including a team leader, project manager, researchers, and developers, ensuring efficient project execution and delivery.
