Summary

Blockchain developer with 4 years building Solidity smart contracts and Web3 dApps. Shipped audited DeFi staking contracts handling $6M TVL, cut gas costs by 22% through storage optimization, and built React + ethers.js frontends.

Experience

Blockchain DeveloperApr 2022 - Present

ChainForge Labs

Developed and deployed Solidity staking and vesting contracts handling $6M TVL across Ethereum and Polygon.
Reduced gas costs by 22% via storage packing, unchecked math, and calldata optimization.
Built React dApp with ethers.js wallet integration and on-chain event indexing via The Graph.

Smart Contract EngineerJun 2020 - Mar 2022

DeFiNova

Wrote 30+ Hardhat test suites achieving 90% contract coverage before mainnet deployment.
Implemented role-based access and reentrancy guards, passing two external security audits with no critical findings.

Security-first signal
Reentrancy guards, audits, and access control show you treat smart contracts as high-stakes code.
Gas and on-chain metrics
Gas savings, TVL, transaction volume, and coverage make blockchain work credible.
Full Web3 stack
Solidity plus ethers.js, React, and indexing prove end-to-end dApp delivery.
Testing rigor
Hardhat, Foundry, and coverage demonstrate the discipline blockchain roles demand.

Sample summaries

Solidity developer with 3 years building DeFi and NFT contracts on Ethereum and Polygon.
Web3 engineer skilled in smart contracts, ethers.js dApps, and The Graph indexing.
Blockchain developer experienced in audited contracts, gas optimization, and multi-chain deployments.

Skills examples

Contracts: Solidity, ERC-20, ERC-721, ERC-1155, OpenZeppelin, upgradeable proxies
Tooling: Hardhat, Foundry, ethers.js, web3.js, The Graph, IPFS
Stack: React, TypeScript, Node.js, security audits, gas optimization

Experience bullets

Built ERC-721 minting contract with merkle allowlist used in 12k NFT launch.
Integrated Chainlink price feeds for collateral valuation in lending protocol.
Set up CI running Slither static analysis on every contract pull request.

Lead with securityAudits, guards, and safe patterns matter more than feature count in Web3.
Quantify gas and TVLGas savings, value handled, and tx volume prove real on-chain impact.
Show testing toolsHardhat, Foundry, and coverage signal production-grade contract work.
Name chainsEthereum, Polygon, Solana, or Base context helps recruiters assess fit.
Link verified contractsEtherscan-verified addresses or GitHub strengthen credibility.

What should a blockchain developer resume include?

Include Solidity, contract types, tooling, audits, gas/TVL metrics, dApp work, and education.

How do I write Solidity resume bullets?

State the contract, optimization or security technique, and result such as gas saved or audit passed.

Should I list chains and tokens standards?

Yes. ERC standards and chains (Ethereum, Polygon) help recruiters match roles.

Do blockchain resumes need audit experience?

Audit-aware coding is a strong signal. Mention guards, static analysis, and external audits.

How long should a Web3 resume be?

One page early career. Two pages for senior engineers with multiple protocols.

How can blockchain resumes pass ATS?

Use exact terms: Solidity, smart contracts, Web3, ethers.js, Hardhat in plain text.
