// 01. ABOUT ME

Background & Focus

I'm a Computer Science graduate focused on backend development with Node.js. My foundation comes from cybersecurity, where I built real tools and completed hands-on labs, and that background shapes how I approach building secure, reliable backend systems.

For my Final Year Project, I built VerifyChain, a credential verification system deployed on zkSync Layer-2, where I handled smart contract development, backend architecture, Node.js integration, and system design.

CS Graduate Node.js Specialist Security-Minded zkSync Layer-2

Backend Architecture

Designing performant Node.js REST APIs, event-driven processes, and database indexes.

Cybersecurity Roots

Prioritizing secure coding standards, threat mitigation, and network protocol fundamentals.

Full-Stack Integration

Bridging backend data pipelines with modern web interfaces and smart contract backends.

Architecture Highlights & Key Points

Smart contracts written in Solidity 0.8.20, tested and deployed with Foundry on zkSync Sepolia (Layer-2), all 13/13 tests passing

Merkle-Proof verification reduces on-chain storage to a single 32-byte root per batch

Merkle Tree batch issuance processes up to 1,000 credentials per batch

Multi-Signature governance requires a 2-of-3 board quorum for institutional onboarding, with a dedicated Governance Dashboard

Backend built with Node.js and Express.js, MongoDB for off-chain indexing, full Ethers.js integration

Issuer Portal for institutions to issue credentials via MetaMask

Verifier Portal for wallet-free QR code verification, averaging 2.8 seconds

Certificate PDF with embedded QR block, auto-delivered via email
