}About Me
I'm a passionate blockchain developer and smart contract engineer with expertise in building secure, decentralized applications. My journey in Web3 began with a fascination for how blockchain technology could reshape traditional systems and create new possibilities.
With a strong foundation in both theoretical concepts and practical implementation, I specialize in developing robust smart contracts, decentralized protocols, and user-focused applications that bridge the gap between complex blockchain technology and everyday users.
My approach combines technical excellence with security-first thinking. I'm particularly interested in DeFi protocols, NFT platforms, and blockchain infrastructure that can scale while maintaining decentralization.
When I'm not writing code, you'll find me researching emerging blockchain technologies, participating in hackathons, and contributing to open-source projects that advance the Web3 ecosystem.

Thesis Research (In Progress)
Blockchain-Based Selective Identity Verification Using NFC Passport Scanning and Zero-Knowledge Proofs
This research explores a novel approach to identity verification that preserves privacy while ensuring security and compliance with verification requirements.
Research Focus
Developing a system that allows users to selectively disclose identity information while maintaining privacy through zero-knowledge proofs.
Key Technologies
NFC passport scanning, zero-knowledge proofs, blockchain for immutable verification records, and privacy-preserving identity management.
Technologies & Methods
Privacy & Security Considerations
The research implements advanced privacy techniques ensuring that users maintain control over personal data while providing cryptographic proof of identity claims without revealing underlying data. This creates a trustless verification framework suitable for decentralized systems.
Initial Research & Concept Development
January 2024 - Complete
Prototype Implementation & Testing
June 2024 - In Progress
Final Implementation & Paper Publication
May 2025 - Planned
Projects
A collection of my blockchain and web3 projects showcasing expertise in decentralized applications, smart contracts, and cryptographic systems.
ArtBlockForge
Community Commerce via Dynamic Tokens and NFTs
Tokenized Community Platform: Built a decentralized platform powered by ArtBlock Tokens, enabling user-driven economies.
Dynamic Pricing Model: Implemented bonding curve-based token pricing that adapts to token supply.
Custom Token Ecosystems: Enabled creation of user-owned communities with custom tokens backed by ArtBlock.
Technical Highlights
- Activity-Driven Tokenomics: Designed pricing algorithms based on user engagement and activity metrics.
- Governance Framework: Created weighted voting using community and ArtBlock tokens to approve products.
- NFT Marketplace: Integrated platform for trading NFTs and goods with resale and royalty systems.
- Reward System: Gamified platform with point-based incentives for participation and transactions.
ChitChat
Decentralized End-to-End Encrypted Messaging App
Secure Chat Platform: Created an E2E encrypted messaging system using AES-256-GCM and RSA-2048 keys.
Decentralized Storage: Used IPFS (via Pinata) for storing encrypted messages and user profiles.
Smart Contract Layer: Wrote Ethereum/Polygon contracts for friend requests, public keys, and IPFS hash mapping.
Technical Highlights
- Client-Side Privacy: Ensured all cryptographic operations were performed in-browser, without central servers.
- Frontend Stack: Built UI using Next.js 15, React, TailwindCSS; hosted on Vercel.
- Key Exchange System: Securely exchanged AES keys via on-chain RSA public key registry.
- UX Flow: Streamlined wallet login, profile setup, friend management, and encrypted chat.
