• 3+ years shipping smart contracts in Solidity on EVM chains, with Solana experience as a bonus—deep grasp of cryptography, consensus, and decentralized systems.

• Security-obsessed: you hunt vulnerabilities (reentrancy, overflows, access control, flash loans) and know your way around MythX, Slither, and formal verification.

• Fluent with Hardhat, Foundry, Truffle, Remix, and The Graph—can spin up contracts fast and deploy to production without breaking a sweat.

• Natural at connecting smart contracts to backend systems, APIs, and protocols—you see on-chain and off-chain as one cohesive system.

• Consulting veteran who thrives in client-facing roles, navigating messy technical requirements and explaining complex tradeoffs to everyone from devs to execs.

• Comfortable deploying and scaling on GCP, AWS, or Azure with monitoring and reliability baked in from day one.

• Self-driven and autonomous, but you actually keep clients in the loop—you stay sharp on emerging standards and security best practices because you genuinely care.

• Dig into client problems and translate their needs into secure, gas-efficient smart contract architecture.

• Design, build, audit, and ship contracts on EVM and Solana—always with security and performance top-of-mind.

• Wire up smart contracts with backend systems, APIs, and external protocols without losing your mind or their funds.

• Spot vulnerabilities and write defensive code that actually holds up against attacks—you're paranoid in the best way.

• Lead technical strategy talks with clients on tokenomics, upgradability, and risk, keeping timelines real and expectations aligned.

• Push Lazer's smart contract game forward by sharing security insights, code patterns, and hard-won lessons with the team.
