As a blockchain developer with 2 years of experience, I have a strong understanding of the fundamentals of blockchain technology, including its architecture, consensus mechanisms, and smart contract development. I specialize in developing decentralized applications (dApps) using blockchain technology and have experience working with a range of blockchain platforms, including Ethereum, Hyperledger, Binance and Solana. During my time as a blockchain developer, I have worked on several projects, including developing smart contracts for supply chain management, implementing blockchain-based voting systems, and creating a decentralized marketplace for digital assets. I have also contributed to open-source blockchain projects and have experience working with blockchain APIs, wallets, and nodes. My technical skills include proficiency in Solidity, JavaScript, Python, Rust and Go, as well as experience with blockchain tools such as Truffle, Hardhat, Ganache, Remix, and Web3.js. I also have experience with DevOps tools such as Docker, Kubernetes, and Git. In addition to my technical skills, I am a strong communicator and a team player. I am comfortable working in an agile development environment and am committed to delivering high-quality code that meets project requirements and deadlines. If you're looking for a blockchain developer with experience developing dApps and working with a range of blockchain platforms, I would be happy to discuss your project and see how I can help.

Blockchain & AI Agent Developer specializing in Solana, Ethereum, Rust, Solidity, Smart Contracts, Agentic AI, and Web3 Infrastructure. I build blockchain systems and AI agents that work in production not just on testnet. My core focus is the intersection of Web3 and Agentic AI smart contracts, autonomous AI agents, and on-chain payment infrastructure. I've deployed on Ethereum, Polygon, Solana, and XPR Network, and built everything from NFT marketplaces to full Layer-1 blockchain ecosystems. What I build: Agentic AI & x402 Payment Infrastructure — Autonomous AI agents that transact on-chain using the x402 HTTP payment protocol, enabling machine-to-machine micropayments without human intervention. Solana-Like Blockchain Ecosystem — Full Layer-1 chain with consensus mechanism, validator nodes, and staking logic built from scratch. NFT Marketplace — Minting, listing, and trading platform with custom smart contracts across multiple EVM chains. Student Certificate Verification DApp — Decentralized credential system using Ethereum + Hyperledger. WASM Smart Contracts on XPR Network — C++ based contracts deployed on-chain. Technical stack: Solidity, Rust, React.js, Node.js, Web3.js, Python, IPFS, Hyperledger, MongoDB — plus AI/ML frameworks for agent development and automation. I work with founders and dev teams building at the edge of blockchain and AI where autonomous systems need to interact with on-chain infrastructure. If your project involves AI agents, Web3 payments, or smart contract systems, I understand both layers. Let's scope your project.
