Data Analytics Projects

Predictive Analytics Capstone/Applied Project Jan. 2016 - May 2016

Worked with ASU admission department, applied analysis with various tools, generated value and guidance to

significantly increase their efficiency with admission process as requested.

Collaborated with team members, preprocessed raw data and evaluated multicollinearity, decided which attributes

should be included for model and created new attributes base on existing ones if needed.

Used Tableau for visualization and generated rules using R for clients better understanding, focusing on which

group of students are most likely to enroll after admitted and which groups are not. Built predictive models with

different algorithms and parameters using Azure ML and SPSS, selected the one with best performance for prediction

use.

Presented outcomes and model, wrote report with semantic explanations for admission department, with

recommendations to optimize the enrollment decision process.

Time-Serious Data Analysis Projects Mar. 2015 - Apr. 2015

Analyzed time-serious financial datasets with ARIMA model and forecasted future results.

Wrote BASS Model function with R, applied it to the sales datasets of a new released smartphone to forecast sale.

Raw Data Cleaning Project Jan. 2015 - Mar. 2015

Explored efficient ways to process given raw datasets with missing value, outliers and other inconsistencies

Implemented different R packages like lubridata, stringr, Hmisc, outliers and editrules for data processing based

on the features of datasets

Wrote functions with Python and R to clean datasets with different input inconsistency patterns into uniform

format

Optimization Project Dec. 2015

Planned my 18 to 23 days trip to New York, DC, Miami and New Orleans with flexible range of time spent in each city.

Collected data of cost for staying at hotel each day in different cities from Hotel.com, and cost for transportations

between cities from CheapOair.com and Wanderu.com.

Built a binary optimization model with pre-set time and logical constraints using Excel Solver to counteract the

fluctuation of hotel and transportation cost thus minimize the total expense.

Predictive/Fraud Detection Project Dec. 2015

To overcome the fraud in an auto insurance company, developed a model to accurately classify fraud claims.

Implemented machine-learning algorithms including Neural Network, KNN and Random Forest; Tested accuracy

rate and evaluated their performance to ensure the best prediction outcomes.

Data-driven Management Project Nov. 2015 - Dec. 2015

Service Optimization Project with Engrained Restaurant

Collected on-site data related to peak hours, service time and customer satisfaction.

Generated correlation between service time and satisfaction, used data-driven quality management tools like

Fishbone Chart, Pareto Graph to identify KPI of service process and provided constructive recommendations to

optimize it.

Professional Experience/Web Test Automation and Database Maintenance

CMSS, Suzhou, China Feb. 2015 - Jun. 2015

Used Python Selenium package for manual test. Decided if the web test automation is applicable on Jenkin base

on the task given and test results. Adjusted the data-driven based framework developed by test team according to

project requirements. From front-end web collect data needed for test; write, test and maintain the script.

Kept monitoring the match of data from front-end and back-end during process, connected to back-end database

and used SQL to check if the new data is written in after POST requirement sent from front-end.

Professional Experience/Data-Driven Project Management

China State Construction/China State Decoration Group Co. Ltd. Beijing, China Jul. 2010 - Aug. 2014

Have professional experience on 4 multi-million dollar construction projects. Worked as project manager, led a 60-people

multifunctional team, completed a 2 million dollar shopping center decoration construction project with the use of data-

driven management, generated 33% profit far exceed the average profit rate.

Collaborated with project financial manager, forecasted project budget based on previous manpower and material

cost

Implemented data-driven detailed management, broke project progress down to segments base on different

features, made schedules and profit-oriented decision tailored to the analysis result of each segment and the

corresponding cash flow status.

Monitored worker performance and recorded their work amount per hour, designed evaluation system to increase

mean value and decrease deviation, made construction schedules based on updated performance data, significantly

increased efficiency, reduced time uncertainty and saved management cost as well.

Consulted with associated company departments during process for legal and technical support, quantified

potential impact as cost data to guide decision making when change of blueprint occurred during construction;

provided weekly reports to company C-suite executives on project progress and financial status.
