Could you build this?
Partial Online Judge (OJ) systems have standard CRUD web portals, but implementing a secure, isolated sandbox to compile and execute arbitrary untrusted code with precise resource limits is difficult.
What it would actually take: The architecture needs a web frontend (e.g. Next.js), a queuing system (Redis/RabbitMQ), and a judge daemon executing inside Linux namespaces, cgroups v2, and seccomp filters. The hard part is building an unbreachable sandbox that accurately measures CPU time and memory down to the millisecond without allowing jailbreaks or denial of service attacks.
