1. Designed and implemented features of a controller that provides information for the AWS SIDR routing protocol for the EC2 UltraClusters network in 100+ data centers.

2. Designed and automated the entire infrastructure for the controller, including AWS resources, metrics, dashboards, and fleet management. With the streamlined infrastructure, the controller can be deployed to any new region within hours.

3. Led the team to build a test automation infrastructure, which can be run both locally and in the cloud. This reduced test time from hours to minutes and enabled efficient testing and validation without requiring hours of manual effort.

4. Skill: Rust, Typescript

1. Designed and implemented a BGP speaker service to announce and withdraw routes to network peers for backbone controllers in 30+ backbone locations.

2. Designed and implemented a service to collect network topology for backbone controllers in 30+ backbone locations.

3. Designed and implemented OS image patching/vulnerability detection service for the computing platforms.

4. Built and maintained a computing platform for internal services with a standardized execution environment in 100+ backbone locations.

5. Skill: Java, Rust, Python,

1. Analyze and measure the performance of wireless network systems.

2. Skill: C, Python, Socket programming, OpenWRT

1. Built a simulation to analyze the APN cloud-based network.

2. Improved the APN network performance by 41 %.

3. Skill: Java, TCP
