POWR (Proof-of-Work Recruitment)
Automated skill-verification platform grading code solutions with Gemini AI
Core Features Implemented
- Sandboxed Monaco Code Workspace: Full-featured in-browser code editor with syntax highlighting, indentation, and automated error squiggles
- Real-Time Gemini AI Code Evaluator: Analyzes submitted solutions for algorithmic correctness, time complexity (Big-O), code structure, and potential vulnerabilities
- Automated Test Suite Runner: Executes candidate submissions against hidden edge-case unit test suites inside isolated environments
- Cryptographic Scorecard Verification: Generates a publicly shareable, tamper-evident candidate evaluation badge with a unique cryptographic hash
System Architecture
- Monaco Code Editor integration with custom language server protocol bindings
- Isolated WebWorker and Docker sandbox for secure code compilation and unit test execution
- Prompt-engineered Gemini evaluation pipeline outputting deterministic, structured JSON evaluation metrics
- Asynchronous grading queues delivering multi-dimensional score breakdowns in under 3.5 seconds
- Cryptographically signed scorecards verifiable via unique public hash
