Web3 Developer Portfolio: What to Include to Get Hired

In Web3, your portfolio is your resume. Hiring managers spend 30 seconds on a traditional resume and 3 minutes on a good portfolio. Here's how to make those 3 minutes count.

Why GitHub Alone Isn't Enough

Common mistakes developers make: - Repos with no README files - Tutorial projects presented as original work - No deployed or live demos - No context on what problems were solved - No explanation of technical decisions

The Ideal Portfolio Structure

1. Landing Page - Your name, photo, and one-line positioning statement - "Smart Contract Developer | Solidity & Rust | DeFi & Security" - Links to GitHub, Twitter/X, and email

2. Featured Projects (3-5 Maximum)

Each project should include:

3. Writing / Technical Blog - 2-3 articles explaining concepts you've worked with - Shows communication skills - Doubles as SEO for your name

4. About Page - Brief background - What you're looking for - Fun fact or personal touch

What Projects to Include

Must-Have: A DeFi Protocol Clone Build a simplified version of a real protocol: - A basic AMM (like Uniswap v2) - A lending protocol (like simplified Aave) - A yield aggregator

This demonstrates you understand financial primitives, not just syntax.

Must-Have: An Original Smart Contract System Something that isn't a tutorial: - A DAO with custom governance - An NFT marketplace with royalty enforcement - A cross-chain bridge prototype

Nice-to-Have: A Full-Stack dApp Connect your smart contracts to a real frontend: - React + wagmi/viem - Wallet connection - Transaction history - Responsive design

Nice-to-Have: An Audit Report Audit someone else's smart contract: - Use Slither and manual review - Document findings professionally - Suggest fixes

How to Present Each Project

Bad: > "A Uniswap clone built with Solidity"

Good: > "SimpliSwap — A constant product AMM supporting ERC-20 token pairs. Built with Solidity + Foundry. Features include flash swap protection, fee collection, and gas-optimized sqrt calculation. Deployed on Sepolia with a React frontend." > > What I learned: Implementing the x*y=k invariant revealed nuances around rounding errors and precision loss that aren't covered in most tutorials. I wrote a blog post about it. > > What I'd improve: Add concentrated liquidity (v3-style), implement better price oracle (TWAP), add multi-hop routing.

Real Portfolio Examples

Here are patterns from developers who landed roles at top Web3 companies:

• Developer A (hired at Uniswap): 4 projects, each with detailed READMEs, deployed on testnets, and accompanied by Twitter threads explaining the architecture
• Developer B (hired at OpenZeppelin): Strong audit portfolio — 6 mock audits of open-source contracts with professional-quality reports
• Developer C (hired at Alchemy): Full-stack focus — 3 dApps with polished UIs, good UX, and clean code

"The portfolio that got me my job had only 3 projects. But each one had a 2000-word README explaining every decision I made. Quality over quantity, always." — Senior developer at a top-10 DeFi protocol
