I build blockchain products that are secure, efficient, and ready to handle real-world transaction volume. Over the past 9+ years, I have designed and developed smart contracts and blockchain protocols across Ethereum, Solana, and major Layer 2 and alternative networks, from ERC token contracts and DeFi protocols to token launch platforms, trading bots, and cross-chain solutions. Most clients come to me in one of two situations : You have a blockchain idea and need it built right the first time; secure contract architecture, optimized execution, thorough testing, and a product that won't become a security or scalability problem after launch. You already have smart contracts or a blockchain product that is expensive to run, vulnerable, slow, or stuck; and you need someone who can understand the existing protocol quickly, identify the real issues, and fix them without breaking everything around it. I am genuinely comfortable in both. What I do end-to-end: - Smart contract development in Solidity and Rust: ERC-20, ERC-721, ERC-1155, proxy patterns, upgradeable contracts, DeFi protocols, governance, staking, and complex on-chain mechanisms - DeFi protocol development: AMMs, Uniswap V2 and V3, custom DEXs, yield farming, lending, flash loans, token economics, and liquidity systems - Token launches: Pump.fun integrations, bonding curves, fair launch mechanisms, memecoin platforms, and tokenomics - MEV and trading systems: arbitrage bots, copy trading, snipers, sandwich attack prevention, and front-running protection - Solana development: Anchor, SPL tokens, Metaplex, PDAs, Cross-Program Invocation, rent optimization, and compute unit efficiency - Cross-chain development: LayerZero, Chainlink CCIP, Wormhole, and blockchain interoperability solutions - Smart contract security: vulnerability assessment, auditing, Slither, Mythril, Forge, automated testing, and security-focused development - Full Web3 development: TypeScript, JavaScript, Python, Web3.js, Ethers.js, dApp development, APIs, automation, and blockchain integrations - Blockchain infrastructure: Ethereum full nodes, Solana validators, Infura, Alchemy, Helius, QuickNode, AWS, Google Cloud, Vercel, GitHub Actions, Prometheus, and Grafana What working with me is actually like: I do not treat smart contracts like ordinary application code. Once a contract is deployed, mistakes can be expensive or impossible to reverse, so I think about security, gas efficiency, edge cases, upgradeability, and scalability before the code goes live. I ask the right questions before development starts, so we do not spend weeks building a protocol that does not match the business model or token economics. I communicate clearly throughout development. You will know what is being built, why a particular architecture was chosen, and where things stand. I test thoroughly before deployment, using tools and frameworks such as Hardhat, Foundry, Anchor, Slither, Mythril, and Forge to catch issues before they reach production. I write clean, documented code that your team can understand, audit, extend, and maintain long after launch. I also work extensively with PostgreSQL, MongoDB, Redis, Graph Protocol, IPFS, and Arweave for blockchain data, indexing, and decentralized storage, along with MetaMask, Phantom, WalletConnect, Chainlink, and Pyth Network integrations. If you are building a DeFi protocol, token launch platform, DEX, trading bot, staking or governance system, Solana program, smart contract, or cross-chain product, let's talk. Send me your idea, protocol design, or existing codebase. I will tell you honestly what I think, recommend the right technical approach, and help you build something secure, optimized, and ready for real users and real transaction volume.
