Hire the Best Hyperledger Developers
in India

I build blockchain systems that run in production — Solidity smart contracts, Hyperledger Fabric networks, and the backend architecture connecting them to real transaction volume. If you're scoping a blockchain product or need an architect to take ownership of a specific piece of the stack, that's where I fit. Most of my work falls into five areas: - Solidity and EVM smart contracts — token standards, staking and vesting logic, DeFi trading, and Chainlink oracle integrations, built with Hardhat and OpenZeppelin - Hyperledger Fabric and private blockchain infrastructure — chaincode development, channel and MSP configuration, automated network deployment - Backend architecture for blockchain products — Node.js and Go services, PostgreSQL data layers, REST and WebSocket APIs - Fireblocks and MPC custody integrations for fintech and payment platforms - AWS, Docker and Kubernetes for deploying and scaling all of the above A few examples of what that's looked like in practice: I built a self-service platform that provisions fully configured Hyperledger Fabric networks on AWS EKS, cutting deployment time from three days to under twenty minutes. I was sole architect on a cross-border payment system settling transactions across three currencies in under two seconds, using Fireblocks for custody and a PostgreSQL ledger built for AML/KYC audit trails. I've also led teams building an EVM-compatible Layer-1 chain from scratch and a full NFT marketplace from contract through frontend. For projects that need more than backend and contracts — a React/Web3 frontend, Unity for blockchain gaming, or design work — I lead a senior team directly, so the architecture stays consistent as the scope grows. If you're working through a specific architecture decision, evaluating your current stack, or scoping a new build, tell me where things stand and I'll give you a straight answer on what it'll take.

I build production Solidity smart contracts and blockchain dApps on Ethereum and EVM chains — staking, vesting, tokens, DeFi logic, and wallet-connected Web3 frontends. I am a blockchain developer. Clients hire me when they need a live smart contract plus a frontend users can actually connect a wallet to — not a demo that dies after the first testnet tx. ━━━━━━━━━━━━━━━━━━ Smart contracts (Solidity) ━━━━━━━━━━━━━━━━━━ • Solidity on Ethereum and EVM (Polygon, Base, and similar L2s) • Tokens, staking, vesting, access control, and DeFi-style logic • Security-first: reentrancy protection, CEI, OpenZeppelin patterns • Tests, gas-aware design, and handover docs so another engineer can maintain it • Tooling: Hardhat / Foundry, ethers.js, OpenZeppelin ━━━━━━━━━━━━━━━━━━ Web3 / dApp frontend ━━━━━━━━━━━━━━━━━━ • Wallet flows (MetaMask / WalletConnect) wired cleanly to your contracts • Next.js + React + TypeScript dApps and admin dashboards on-chain • Clear UX for mint, stake, claim, and token actions — not just a contract ABI I’m not the right fit for “quick ERC-20, no tests, no review.” I am the right fit when funds or users will touch the contract and it has to stay correct. ━━━━━━━━━━━━━━━━━━ How I work ━━━━━━━━━━━━━━━━━━ • Start from chain, threat model, and constraints — not random features • Flag risks early (reentrancy, access control, UX, gas, upgradeability) • Ship testable, documented Solidity that’s easy to audit and hand off • Communicate timelines, trade-offs, and what’s realistic on-chain • Work independently or with a remote product team ━━━━━━━━━━━━━━━━━━ Proof I’ve shipped ━━━━━━━━━━━━━━━━━━ • Production Web3 / DeFi: live dashboards, wallet flows, and contract integrations • Open-source contributions in the Ethereum ecosystem • Selected by Google for open source — GSoC 2026 (production automation, not a class demo) • Upwork: 100% Job Success — clients get working systems, not concept code (GitHub is on this profile — I’ll send specific Solidity / dApp repos in chat.) ━━━━━━━━━━━━━━━━━━ What you can expect ━━━━━━━━━━━━━━━━━━ • Clear scope and honest estimates • Correctness first when users or money are on-chain • Clean documentation and handover • Direct communication — no hype, no “guaranteed audit-proof” claims ━━━━━━━━━━━━━━━━━━ Let’s talk ━━━━━━━━━━━━━━━━━━ Hiring for a Solidity smart contract, an Ethereum / EVM dApp, or a Web3 frontend on top of existing contracts? Send a short note with: 1) chain (Ethereum, L2, etc.) and what you’re building 2) current stage (idea / testnet / mainnet) 3) deadline and budget range I’ll reply with an approach, the main contract risks, and whether I’m a good fit — before any code starts. ━━━━━━━━━━━━━━━━━━ Tech & search terms ━━━━━━━━━━━━━━━━━━ Blockchain Developer · Blockchain Development · Blockchain Engineer · Solidity Developer · Solidity Smart Contracts · Smart Contract Developer · Smart Contract Development · Ethereum Developer · Ethereum Smart Contracts · Web3 Developer · Web3 dApp · DeFi Developer · EVM Developer Solidity · Smart Contract · Smart Contracts · Ethereum · Blockchain · Web3 · DeFi · dApp · DApp · Cryptocurrency · Token Development · ERC-20 · ERC-721 · NFT · Staking Contract · Vesting Contract · Token Vesting · Yield Farming · Liquidity Pool · DAO · ICO · TGE Ethereum · Polygon · Base · Arbitrum · Optimism · BNB Chain · BSC · EVM · Layer 2 · L2 Hardhat · Foundry · OpenZeppelin · ethers.js · web3.js · Wagmi · Viem · WalletConnect · MetaMask · RainbowKit · The Graph Next.js · React · TypeScript · Node.js · Web3 Frontend · Wallet Integration · Smart Contract Integration · Gas Optimization · Reentrancy Protection · Access Control · CEI · Contract Testing · Mainnet Deployment Keywords: Blockchain Developer, Blockchain, Solidity, Solidity Developer, Smart Contract, Smart Contracts, Smart Contract Developer, Ethereum, Ethereum Developer, Web3, Web3 Developer, DeFi, dApp, DApp, Cryptocurrency, NFT, ERC-20, ERC-721, Token, Staking, Vesting, EVM, Polygon, Base, Hardhat, Foundry, OpenZeppelin, ethers.js, web3.js, MetaMask, WalletConnect, Next.js, React, TypeScript, Blockchain Development, Smart Contract Development, Ethereum Smart Contracts, Web3 dApp, Solidity Smart Contracts
