Look inside

You’re a new developer at UMET Inc., an e-commerce platform that’s modernizing its backend technology stack with Rust. Your task is to create a simple HTTP service that looks up sales tax rates for U.S. ZIP codes and then deploy it in a lightweight container. To build the service, you’ll use Rust Tokio and hyper crates. You’ll compile, run, and test it in a lightweight WasmEdge container and use GitHub Actions to automatically test and validate any changes that you make. When you’re finished, you’ll have hands-on experience building, updating, and testing a minimally viable microservice using Rust and WebAssembly.

This project is designed for learning purposes and is not a complete, production-ready application or solution.
