I'm a certified Ethereum Developer with Solidity. I can help you to develop secure smart contracts and descentralized applications using different tools such as Remix, Truffle, Metamask, Infura, Ganache, Javascript and Web3. Develop secure smart contracts implementing unit testing in truffle. Deploy your contracts to a testnet or the mainnet.

- Implemented the Plasma-Free protocol (PF) based on the Polygon’s Validium CDK. Modified and tested the contracts responsible for the rollback rolling, managing the states and the updates of the L2 network.
- Enhanced the Go-based off-chain Polygon’s system to support forced batches as an exit mechanism.
- Developed the ARST token with Multisignature capabilities and Vault contracts (ERC-4626). The token was deployed and verified on mainnet in several networks such as: Tron, Avalanche, Stellar, Binance SC, Base, Worldchain and Injective.
- Implemented a multichain listener (NestJs) for the on-ramp/off-ramp system to detect onchain deposits of the ARST token and complete the disbursement process in Base, Gnosis, BSC, and Tron.
- Collaborated with a cross-functional team to ensure the successful integration of the smart contracts into Web3 applications
