SUMMARY

5 years of experience in data analysis, background in Fortune Global 500 enterprises

Led overall data analysis work and exploratory project modeling within the company, with extensive experience in building data management systems and implementing projects.

WORKING EXPERIENCE

Database Construction and Management:

• Led the construction of the company's clinical trial database from scratch. Identified inefficiencies and low data quality issues caused by storing data with Excel and shared drives. Standardized the data, established storage structures, and created a scalable clinical trial database based on MySQL to facilitate data accumulation and established several user-friendly dashboards, improving daily work efficiency by 40%.

Data Analysis and Modeling:

• Led the team's daily data analysis work, gaining an in-depth understanding of each project's requirements. Independently produced analysis frameworks, developed SOPs for different projects, and created visualization tools using R and Shiny.
• Led the analysis and modeling of exploratory experiments, combining business team expertise to analyze and select appropriate metrics for predictive model construction, providing experimental optimization suggestions from a data perspective. Initially detected the impact of different skin types and weather conditions for further study on the discovery of factors which may lead to noodling.

Data Analysis Training:

• Conducted specialized training sessions twice (Hypothesis testing, regression analysis), enhancing team members' data awareness.

Data Analysis and Modeling:

• Responsible for supporting the data analysis needs of the laboratory team, understanding specific project requirements, selecting appropriate analysis methods and implementing them. Provided support to the laboratory team approximately twice a month on average.
• Collaborated with the laboratory team on a predictive model construction project, selecting important features to optimize and iterate the model, increasing the accuracy from 50% to 70% compared to the expert-based model.

Data Management:

• Led the quality management of clinical trial data in China. Deeply understood the data usage needs of different teams, established standardized data entry protocols, and wrote data processing scripts, reducing the time required for standardizing raw data sets from one week to half a day.

Data Analysis and Mining:

• Served a leading state-owned bank client, leading a customer mining project for life insurance marketing. Addressed the business pain point of difficulty in precise marketing for insurance products by designing mining methods and processes. Utilized SQL, GSQL, and graph algorithms, uncovering 110,000 business opportunity customers and creating 5 customer group profiles. Compared to customers without precise marketing, the average order amount increased by 16%.
• Participated in projects such as SME loan fraud prevention, industry index research, and group equity penetration, independently completing the analysis work.

Project Management:

• Responsible for after-sales service for clients in Europe, America, and Southeast Asia. Led resource allocation and internal and external communication coordination, overseeing project progress, quality, and risk. Completed approximately 40 overseas customer service projects annually.
