Message

At Amazon, I lead the design and implementation of production software systems, with a focus on maintainable code, reliability, and scalable engineering practices. I guide software evolution across large codebases and contribute backend and platform changes in a high-scale environment.

Before my current role, I delivered and maintained production software at Amazon, AWS, and Facebook. My work included backend functionality, system enhancements, and service improvements in large-scale engineering environments.

At University of Michigan-Rackham Graduate School, I proposed a vehicle platooning control algorithm that considered security and safety requirements. I evaluated it with the PLEXE simulator, modified simulator source code to verify the algorithm, and published research papers.

At Shanghai Jiao Tong University, I developed an automatic analysis platform for studying advertisement traffic consumption. I used it to capture and analyze router traffic, and published an IEEE GLOBECOM paper based on the results.
