Description

Priyanshu Choudhary Dear Hiring Team, My name is Priyanshu Choudhary, and I’m applying for the Web3 / Blockchain Developer role. I’ve been working deeply in smart contract development with a focus on security and low-level EVM behavior. Most of my work has involved building and testing Solidity systems using Foundry, with heavy use of fuzzing, invariant testing, and adversarial thinking to identify edge cases and failure modes. Recently, I built a cross-chain rebase token system where users deposit ETH into a vault and receive dynamically accruing balances, with interest preserved even when bridged across chains using Chainlink CCIP. This required designing custom accounting logic, handling state consistency across chains, and writing fork-based tests to simulate full flows locally. I’ve also implemented account abstraction systems across multiple environments, including ERC-4337 on Ethereum/Arbitrum and native account abstraction on zkSync. This involved working directly with EntryPoint contracts, UserOperation validation, gas sponsorship logic, and low-level transaction handling. In addition, I’ve built DeFi primitives such as an overcollateralized stablecoin engine with liquidation mechanics and price feed integration, along with gas-efficient systems like Merkle-based airdrops with EIP-712 signatures. Across these projects, I prioritize correctness and security, using tools like Foundry, Slither, and formal verification approaches where applicable. What interests me about this role is the opportunity to work on real-world systems where security and correctness matter. I’m comfortable working independently, diving into unfamiliar codebases, and reasoning about complex execution flows at the opcode level when needed. I’m looking to contribute meaningfully from day one while continuing to sharpen my skills in building and securing decentralized systems. Thank you for your time and consideration. Best regards, Priyanshu Choudhary
