I am a master student at Emory University Goizueta Business School pursuing a degree in business analytics. This program is a one-year, immersive program that combines business, data, and technology for Business Data Scientist in a data-driven world. In the fall semester, I initiated several data science and business analytics projects, covering topics ranging from programming-heavy quantitative time series analysis to business-oriented decision analytics. In Binance Trading Bot, I implemented recurrent neural network (RNN) for real-time cross-currency price forecast, based on custom-built data pipeline in AWS by using Binance WebSocket API. In FedEx Business Challenge, I leaded a team of three student consultant and provided multiple analytical frameworks on FedEx Delivery Utility Optimization. In Travelers Insurance Fraud Modeling Competition, I explored the behavior of different available ensemble methods, XGBoost and LightGBM, and produced the best performance model in accuracy. Some other interesting projects include Enron Fraud Case Study, where techniques of social network analytics are used for understanding the origin and cause of financial frauds within large organizations, and Ad-Click Prediction, where I developed embedded layer neural network architecture in TensorFlow for click-through rate (CTR) prediction using a 52 million+ database. Also, as a main contributor, I was involved in designing two interactive Tableau dashboard, NBA Multi-level Analysis Dashboard and Lewis Hamilton Career Dashboard.

During my years in UCSB, I received comprehensive training as a mechanical engineer. I had the chance in working on one of the largest and most complex projects, BabyBOOST Capstone Project. The capstone team consisted of five mechanical engineers and five electrical engineers, and utilized $6,700+ budget in designing the first ever home-use automated ball therapy device for infants with cerebral palsy (CP). During the one-year development stage of BabyBOOST, I conducted several multi-physics simulation for optimizing mechanical design, including Electric Box Heat Transfer Analysis for motor safety and rigid body analysis for structure integrity. Some other interesting projects include Portable Vacuum Cleaner, where I designed and assembled a handheld vacuum cleaner during the pandemic in my home work station; Oil Leak Simulation, where I simulated oil spill using discrete numerical approximation based on advection and diffusion; Design Optimization for Simply Supported Cantilever Beam, where  I used meshed SOLIDWORKS objects in COMSOL to search for the best design of beam with minimal building material under several pressure conditions. I also include four of my favorite mechanical engineering lab work including Vibrating Beam Analysis, Pipe Flow Analysis, Transient Heat Analysis, and Tensile Testing.
