Freelancer Overview

Although my primary role has been Java backend development, I have extensive experience working with large-scale business data processing, data governance, data cleaning, and rule validation across multiple healthcare information systems and internet platform projects. I am proficient in MySQL, Oracle, Redis, and MongoDB, and capable of organizing, classifying, analyzing, and optimizing large volumes of structured business data. Through SQL, stored procedures, and backend APIs, I have supported data processing and training-data-related workflows. In projects such as HIS systems, internet hospitals, and smart healthcare platforms, I frequently worked with user behavior data, medical service data, and payment-related data, developing a strong awareness of data accuracy, consistency, and sensitive information handling. In addition, I have a solid technical background in Java, Spring Cloud, and MyBatis, with experience in multithreading, concurrent programming, SQL optimization, and system performance tuning. These skills enable me to efficiently support AI training data platforms, including data processing, API development, and workflow automation. I am a fast learner with strong analytical and problem-solving abilities, capable of quickly understanding complex business rules and participating in requirement analysis, system design, and process optimization in both new product incubation and large-scale enterprise projects.
