Build full-stack dApps with React.js/Next.js, Web3.js/Ethers.js, and wallet integrations (MetaMask, Phantom, WalletConnect)
Implement cross-chain features using LayerZero, Wormhole, or Axelar (bridging, syncing, wrapped tokens)
Write secure, gas-optimized contracts and perform thorough testing (Mocha, Jest, Anchor test suite, Hardhat, Foundry)
Integrate backend services with Node.js, GraphQL/REST APIs, PostgreSQL/MongoDB, and Redis (optional)
Automate deployments using Docker and CI tools (GitHub Actions, GitLab CI)
Monitor and troubleshoot on-chain activity using tools like Tenderly, Etherscan APIs, and Solana Explorer
Collaborate with frontend and DevOps teams to ensure great UI/UX and scalable infrastructure

Required Skills & Experience:

3+ years of full-stack development experience.
1+ year of hands-on Solana smart contract development (Rust + Anchor).
Proficiency in Solidity and EVM tools (Hardhat, Foundry, Truffle).
Strong knowledge of Web3 wallet integration, blockchain architecture, and RPC interactions.
Experience with DeFi, NFTs, DAOs, and decentralized storage (IPFS, Arweave).
Familiarity with authentication protocols like JWT, OAuth2, and SIWE (Sign-In With Ethereum/Solana).
Understanding of smart contract vulnerabilities and Web3 security best practices.
Experience with zk-rollups (zk-SNARKs, zkSync, StarkNet).
Exposure to other chains like Cosmos, NEAR, or React Native/mobile dApps.
Contributions to open-source blockchain projects.
Knowledge of MEV, gas fee estimation, and bridging mechanics across chains.
