The Challenge:
Security vs. Speed.

Building a simple CRUD app is easy. Building a platform that allows users to execute arbitrary code on your server is a security nightmare. We needed a system that could:

  • Prevent Malicious Attacks: Users shouldn't be able to access the file system or infinite loop the server.
  • Instant Feedback: Developers hate waiting. Code execution had to happen in under 100ms.

Additionally, the client needed AI Proctoring features to ensure test integrity during remote interviews, including browser lockdown and tab-switch detection.

More than just a Compiler.

AI-Powered Proctoring

Advanced browser lockdown prevents tab switching. AI algorithms analyze user behavior to flag suspicious activity during coding assessments.

Community Pods

Domain-based access control creates private "WhatsApp-style" learning groups for focused study.

Skill Graphs

Visualizing user progress across standard DSA topics (Arrays, Trees, DP) using chart.js.

Secure Authentication

Integrated Firebase Auth for seamless Google/GitHub social logins and secure session management.
