✅ Include keywords from the job description
✅ Spell out acronyms at least once
✅ Keep file size under 1MB
✅ Use a standard file name: FirstName_LastName_Resume.pdf

**Keywords to include:**
- Solidity, Smart Contracts, Ethereum, DeFi
- Web3, dApps, NFTs, Layer 2
- Security, Auditing, Gas Optimization
- DAO, Open Source, Community

Tailoring for Smart Contract Developer roles:

**Focus on:**
- Solidity, Vyper, Rust experience
- DeFi or NFT project experience
- Gas optimization techniques
- Unit testing and deployment

**Highlight:**
- Number of contracts deployed
- Total value locked (TVL)
- Gas savings achieved
- Audit results (if any)

**Example bullet:**
"Developed and deployed 7 smart contracts for a yield farming protocol, achieving $8M in TVL with gas costs 40% below average."

Tailoring for Security Auditor roles:

**Focus on:**
- Security analysis tools (Slither, Mythril, Echidna)
- Formal verification experience
- Vulnerability discovery and reporting
- Bug bounties or audit history

**Highlight:**
- Number of audits performed
- Critical vulnerabilities found
- Public disclosures (CVEs)
- Security best practices

**Example bullet:**
"Audited 15+ smart contracts, identifying 23 critical vulnerabilities and securing $50M+ in user funds."

Tailoring for Web3 Architect roles:

**Focus on:**
- System design and architecture
- Cross-chain solutions (bridges, layer 2)
- Infrastructure decisions (node providers)
- Team leadership and mentoring

**Highlight:**
- Architecture decisions and their impact
- Scalability improvements
- Cross-chain integration experience
- Team size and project scope

**Example bullet:**
"Designed and led the architecture for a cross-chain NFT marketplace, integrating Ethereum, Polygon, and Solana with a unified order book."

Common mistakes to avoid:

❌ **Listing skills without context**
   - Bad: "Skills: Solidity, Ethereum, Web3.js"
   - Why: Shows you know them, but not how you've used them.

❌ **Forgetting to include GitHub links**
   - Bad: No links to your work
   - Why: Blockchain recruiters review code contributions.

❌ **Using buzzwords without evidence**
   - Bad: "Revolutionary DeFi expert"
   - Why: Sounds hollow without metrics or examples.

❌ **Omitting open source contributions**
   - Bad: Not mentioning open source work
   - Why: Open source is highly valued in blockchain.

❌ **One-size-fits-all resume**
   - Bad: Same resume for all roles
   - Why: Each role has different priorities.

How to fix common mistakes:

**Before:**
"Built a DeFi protocol using Solidity."

**After:**
"Built a DeFi lending protocol using Solidity that reached $3.5M in TVL within 3 months of launch."

**Before:**
"Skills: Solidity, Ethereum, Web3.js, Hardhat."

**After:**
"Skills: Solidity (4+ years), Ethereum (mainnet and testnets), Web3.js (decentralized app integration), Hardhat (testing and deployment)."

**Before:**
"Open source contributor."

**After:**
"Open source contributor: 15 merged PRs to the Ethereum protocol repository, with 3 major feature implementations."
