Web dashboard management and data visualization provision. ►Developed and managed web dashboards for revenue, cost, and machine log data visualization, and implemented single sign-on, asymmetric encryption-based algorithms, and a role-based access control system using RESTful APIs. ►Designed and implemented TypeScript-based frameworks for searching, chart creation, and form rendering, reducing development time for individual dashboard projects by at least one-third and increasing functional efficiency by ninefold. ►Optimized dashboard's storage architectures and real-time search, and reduced server response time by rewriting the format conversion program. ►Achieved a 200% increase in development efficiency for a single dashboard project. Skills: Modular programming, data normalization, data visualization, TypeScript, RESTful APIs, asymmetric encryption-based algorithms

R&D - Chinese characters full-text format search database. ►Developed a Chinese characters full-text search database with customized full-text search database and index creation based on the inverted index, resulting in higher efficiency of exact search of Chinese characters than the current database software (SQL Like). ►Implemented the search algorithm, indexing, and sorting functions using NLP techniques such as HMM, SVM, TF-IDF, and inverted index. ►Designed and implemented non-dictionary-based, word segmentation, word vector, and article categorization by SVM to improve the accuracy of search results. ►Optimized the search engine's performance, reducing the search time by 90% and improving the scalability of the system. Skills: Full-text search database, inverted index, NLP, HMM, SVM, TF-IDF, non-dictionary-based search
