🏛️ VSBEC IT VAULT — ACADEMIA–INDUSTRY INTEGRATED PLATFORM

Enterprise Institutional Task Governance, LeetCode/GitHub Daemon Sync & Sandboxed Assessment Engine

📦 Official GitHub Repository • 🌐 Production Live Demo

1. 📌 Problem Statement & Context

In engineering institutions, departmental task tracking and algorithmic prep face severe systemic bottlenecks:

• 📑 Fragmented Deliverables: Academic lab tasks are scattered across Google Forms, WhatsApp groups, and paper records, resulting in lost records and zero auditability.
• 💻 Coding Velocity Blind Spot: Students solve algorithmic challenges on LeetCode and GitHub without faculty having real-time visibility into daily streaks or mastery.
• ⏱️ Severe Grading Latency: Manual review creates multi-week backlogs, preventing faculty from providing actionable, personalized mentorship.
• 🏢 Corporate Recruitment Disconnect: Placement coordinators lack empirical, tamper-proof proof of students' sandboxed multi-language programming competency.

2. 🔍 Existing Solutions & Critical Gaps

Feature / Dimension	Conventional LMS (Moodle / Classroom)	Manual Spreadsheets & WhatsApp	🏛️ VSBEC IT Vault
Sandboxed Code Execution	❌ None	❌ None	✅ Isolated C, C++, Java 17, Python 3 Sandbox
Competitive Profile Telemetry	❌ None	❌ None	✅ Automated LeetCode GraphQL & GitHub REST Sync
Hierarchical Approval Workflow	❌ Single-Tier Only	❌ None	✅ 3-Tier Pipeline (Peer → Faculty → HOD)
Automated Instant Alerts	⚠️ Email Only (Low Open Rates)	❌ None	✅ Telegram Webhooks + Web Push + Email Failover
Anti-Cheat Proctoring	❌ Paid Third-Party Addon	❌ None	✅ Integrated Webcam PIP & Fullscreen Lockdown

⚠️ Critical Limitations of Existing Alternatives:

• 🚫 Zero Sandboxed Execution: Traditional systems treat code as plain text files without isolated compilation or test suites.
• 🛑 Subjective Evaluation Bias: Without rigid rubrics and verification chains, grading consistency varies widely across evaluators.
• 📴 Communication Blackouts: Critical placement and lab deadlines are missed due to unreliable email notifications.

3. 💡 Proposed Solution & Architectural Innovation

VSBEC IT Vault is an institutional task governance, real-time coding competency tracking, and corporate recruitment ecosystem engineered for the Department of IT, VSB Engineering College:

• 🏆 SIH 2026 Internal Hackathon Top 50 (Official SIH Portal Nominee): Shortlisted in the SIH 2026 Internal Hackathon (Top 50 out of 300+ teams) with official SIH portal submission.
• 👥 Real-World Implementation: Actively adopted by 365+ enrolled students in the Department of Information Technology for centralized academic governance, LeetCode habit tracking, and corporate coding assessments.
• 🛡️ 3-Tier Verification Pipeline: Enforces an audit trail where tasks are peer-reviewed by Coordinators, validated by Advisors, and authorized by HOD.
• ⚡ Algorithmic Momentum Daemons: Schedulers poll LeetCode GraphQL and GitHub REST APIs daily, computing solve velocity and commit streaks.
• 💻 Sandboxed Multi-Language Compiler: Isolated execution runtime supporting Monaco Editor assessments for C, C++, Java, and Python.
