[Feature]: Docker-based Code Execution Sandbox

[Vachhani-Tapan]

Feature/Project Proposal

I would like to propose a secure, isolated code execution sandbox that allows users to compile and run their code directly within the browser while practicing for technical coding interviews.

Problem Statement

Currently, users can only write code in a static editor during their technical prep. Without the ability to run their code, test against edge cases, or view stack traces, users cannot verify if their logic is actually correct, forcing them to leave the platform to use local IDEs or third-party compilers.

Proposed Solution

The project could build a CodeExecutionController that delegates raw user code to a DockerSandboxService. Using the Docker Engine SDK, the backend will spin up ephemeral, lightweight Alpine Linux containers. The code is mounted, executed with strict memory/CPU limits and a 5-second timeout, and the stdout/stderr logs are sanitized and streamed back to the frontend terminal UI.
