Solidity Developer
I am a passionate and results-driven Solidity Developer with three years of experience in designing, developing, testing and deploying secure and scalable smart contracts and blockchain solutions. Proficient in Solidity, and test frameworks as Hardhat and Foundry, also with great knowledge in JavaScript, Typescript and GraphQL, I have successfully led projects such as complex smart contract architecture migration, design the complete architecture of the proects I have worked on, and the implementation of advanced features like Cross Chain Interactions and advanced testing methodologies like fuzz testing, invariant testing and formal verification.
My expertise extends to building decentralized applications (dApps), optimizing gas usage, and maintaining subgraph indexers for protocol analytics. I thrive in collaborative environments and have a proven track record of delivering robust, high-quality products under tight deadlines.
Beyond my technical skills, I bring strong leadership and problem-solving abilities honed through my role as a Lieutenant in the Firefighter Department, where I managed teams in high-pressure situations. I am fluent in both English and Spanish and am always eager to take on new challenges in the blockchain space.

Experience
Solidity developer
LeaderDao.ai 2023 - 2023
● Refactor smart contract code base to save gas, this allow to avoid denial of service in some methods due to running out of gas. ● Write and maintain subgraph indexer for protocol interaction and stats. Tech stack: solidity, graphQL, hardhat.
Web3 Smart Contract Developer
Takadao 2023 - 2025
● Migration from existing contracts from Factory Pattern to Diamond Pattern using solidity, this to avoid smart contract size limit introduced in EIP-170. ● Wrote version 2 of Takaturn protocol, this not only includes Smart Contracts, also interaction scripts, deployment scripts and comprehensive tests, managing nearly 90% of coverage, all this using hardhat, this along with multiple simulations in Tenderly to deliver a robust product. Writing 82 out of 101 of protocol PRs. Repository here, and Smart Contract deployed here. ● Start the development of the main product Takasure. This product is build using foundry and includes design and architecture, unit tests, fuzz tests, invariant tests and formal verification with Certora. Also were deployed here a Smart Contract to prejoin to the product, this involved a lot of work including building oracles and cross chain interactions ● Write and maintain subgraph indexer for protocol interaction and stats, in both produts. ● Collaborate with customer support. ● Collaborate in meetings where we negotiate partnership with other startups, and audit firms. Tech stack: solidity, javascript, typescript, graphQL, hardhat, ethers, tenderly, foundry, certora.
