• Led efforts in maintaining, optimizing, and refining the protocol core components, and its associated plugins, ensuring robust performance and scalability.
• Developed several npm packages designed to facilitate interaction with OSX contracts and streamline deployment processes.
• Conducted in-depth research on OpenZeppelin, Zodiac, and Llama permission managers, gathering valuable insights to enhance OSX’s permission management system.
• Architected and implemented a new governance plugin for OSX that enables proposals to progress through multiple governance stages before final approval, allowing for more complex and flexible DAO governance workflows.
• Improved, fixed, and maintained the protocol's subgraph, optimizing data indexing and retrieval for better performance and reliability across the ecosystem.

• Developed Smart Contracts for connecting banks broadly to provide intraday operations and implemented CBDC on private blockchains.
• Designed and created interfaces to describe behaviors and libraries to extend the default datatypes focused on understanding the Solidity inheritance.
• Increased security by managing roles and permissions in the Smart Contracts and making the Smart Contracts upgradeable using proxies, following EIP1967.
• Used Golang to communicate the Smart Contracts and Geth to create private blockchains and orchestrate the system.
• Automated the testing process to keep Smart Contracts functional and secure.
• Proposed the use of Hardhat instead of Truffle reducing significantly the pipeline runtime and improving the simplicity of the test.

Developed Smart Contracts for decentralized apps using mainly Solidity with HardHat and JavaScript. - Used Openzeppelin tokens (ERC20, ERC721, ERC777, ERC1155) and Governor contracts, adjusting them to solve specific problems and following the Ethereum Improvements Proposals. - Designed and implemented solutions to recreate the needed features testing them.
