Edubuk-TruCV & TruJobs (AI + Blockchain)

Overview: Edubuk is building an AI-driven CV-to-JD Matching dApp on the blockchain, integrating MANTLE to revolutionize the hiring process by ensuring tamper-proof verification and AI-powered precision in talent matching. This dApp will leverage blockchain for credential verification (full CV, each credential being verified: TruCV) and AI for intelligent job matching (TruJobs), creating a seamless and trust-driven hiring ecosystem for universities, students, and employers.

Problem Statement: Recruiters face a growing challenge of fake credentials, inefficient hiring processes, and misalignment between candidates’ skills and job descriptions. Traditional job-matching systems rely on self-reported data, making validation time-consuming and unreliable. Moreover, students struggle to get visibility for relevant jobs that align with their verified skills and credentials.

Solution: Edubuk’s AI-driven CV-to-JD Matching dApp on the blockchain provides:

1. Blockchain-Based Credential Verification – CVs, certificates, and academic records are e-sealed and timestamped on the blockchain using Educhain, ensuring authenticity and eliminating fraud.

2. AI-Powered Job Matching – The dApp leverages NLP & Deep Learning algorithms to match verified student profiles with job descriptions based on skills, education, and experience.

Impact & Traction:

• 20+ University Partnerships in India, enabling seamless adoption across their student base.

• Access to 10 Million+ Students, creating one of the largest verified talent pools for employers.

• Reducing Hiring Fraud – Blockchain-backed verification removes fake degrees and misrepresented resumes.

Faster Hiring Cycles – AI-driven CV-to-JD matching optimizes hiring efficiency, cutting down recruitment time.

Tech Stack:

• Blockchain: MANTLE for credential verification (CV on Chain)

• AI/ML: NLP models, Deep Learning for JD-CV matching

• Smart Contracts: Solidity-based contract execution

• Frontend: React, TypeScript, Tailwind CSS

• Backend: Node.js, Express.js, MongoDB, Flask (for AI APIs)

• Smart Contracts: Solidity, Remix IDE, ethers.js

• Network: MANTLE Test Network

• AI & NLP: SentenceTransformer, PyTorch

• Machine Learning: Cosine Similarity for text matching

• Data Processing: Pandas for CSV export

• Decentralized Storage: IPFS

• Authentication & Security: JWT, OAuth, crypto libraries

Web3 Integration: Decentralized storage for CVs and credentials

How It Works

Reading Input Files (Preprocessing – NLP)

• Takes a folder of resumes (CVs/) and a job description file (jd.txt).

• Extracts text from PDF and TXT files using PyMuPDF (fitz).

Cleaning & Processing Text

• Removes special characters, punctuation, and extra spaces.

• Converts text to lowercase for uniformity.

Converting Text into Numerical Representation

Uses SentenceTransformer (all-MiniLM-L6-v2) to generate numerical embeddings. Embeddings capture the semantic meaning of sentences.

Matching Resumes with JD

• Computes cosine similarity between resume and job description embeddings.

• Calculates a base similarity score.

Skill-Based Weighting

• Supports Must-Have, Good-to-Have, and Bonus Skills with custom weights.

• Computes a weighted score based on skill similarity.

Ranking & Output

• Resumes are sorted by their weighted matching percentage.

• Generates a results.csv file with resumes and their similarity scores.

Result: A far more accurate and meaningful resume-job matching, beyond simple keyword checks.

Why This dApp is a Game Changer?

First-of-its-kind integration of AI job-matching + blockchain verification in university hiring.

Scalable adoption across universities, recruiters, and students with blockchain-based trust.
