• Built Kaskade, an efficient and highly-scalable benchmarking infrastructure with Node.js. Kaskade uses Node’s worker threads for multi-threading, to allow one machine to simulate thousands of HTTP clients.

• Implemented a graphic UI frontend with Electron + React. We use React to build a fast-responding and performant frontend. We use Electron so we can build our frontend as a desktop App while still leveraging the widely-used HTML / CSS / JS / React tech stack. This improves our development speed.

• Our frontend streamlines the core user journey from configuring a benchmark to running and visualizing the result. It solves a major usability challenge of existing command-line based benchmarking tools.

• Defined a modular benchmark config to allow users to reuse shared building blocks such as HTTP requests and sessions across multiple tests.

• Designed SQL schema and use PostgreSQL to persist benchmark configs and historic results. Organizing benchmark results with a SQL database allows us to perform structural and complex queries over historic results.

• To benchmark the performance of an HTTP server cluster, Kaskade can integrate with Kubernetes to run distributed tests from multiple machines and against multiple HTTP servers.

Ruijie Inc.

• Built a responsive dashboard for an aquaculture farm to visualize data from 1,500+ sensors with TypeScript, Next.js, React.

• Reduced data discovery time by 35% for management and research teams.

• Implemented Express.js backend and efficient PostgreSQL queries to analyze and aggregate sensor data.
