Look inside

As a software engineer for Boutique, a software development company, you're tasked with adding search, upload, and download functionality to an ASP.NET Core HTTP API that Boutique is building for its client, RobotsInc. To enable the frontend to navigate through existing data structures, you’ll add several child endpoints, as well as an endpoint for criteria-based searches. You’ll also implement endpoints for binary photo uploads and downloads according to the OpenAPI specification, and you’ll verify your implementations are correct by testing manually with Swagger UI as well as with automated integration tests. When you’re finished, RobotInc’s employees will be able to upload photos and notes to document and report on their robot inspections.

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