    "displayName": "Online Exam / Assessment (Next.js, PostgreSQL, Redis, Docker, TypeScript)",
    "description": "A secure online examination platform supporting timed assessments,\nauto-grading, and proctoring integration for educational institutions\nand certification bodies. Next.js delivers the exam interface with\nserver-side session validation to prevent answer tampering and\nclient-side timers with server reconciliation. PostgreSQL stores\nquestion banks, exam configurations, student responses, and grading\nrubrics with row-level security per institution. Redis manages exam\nsession state, countdown timers, and rate limiting for submission\nendpoints. Docker containers isolate code execution sandboxes for\nprogramming assessments. WebSocket connections via Socket.IO enable\nreal-time proctor monitoring dashboards. The tradeoff is preventing\nexam fraud across diverse client environments and scaling concurrent\nexam sessions during peak periods.\n",
