Partial The question bank, UI, and automated grading are buildable with vibe coding. Running real PySpark and SQL reliably in the browser and grading them at scale requires non-trivial infrastructure and sandboxing.
What it would actually take: Use a sandboxed execution backend (containers or Pyodide/DuckDB-WASM for SQL) with a grader that compares result sets against reference outputs. The hard parts are secure isolated Spark execution and the curation of high-quality data-engineering problems, which requires real data engineering expertise.
