About
Former aerospace engineer, now working as a machine learning engineer (data scientist) and Solidity developer. I believe that my engineering background, along with my skills in math, logic, and analysis, make me an excellent fit for tasks and activities that require attention to detail, mathematical modeling, programming logic, and process engineering.
Solidity Developer & Smart Contract Engineer.

- City: Curitiba, Brazil
- Degree: Masters in Engineering
- Languages: English, Portuguese, and German
I am curious, adaptable, easygoing, and a fast learner. I am always open to new challenges. There is no obstacle too hard to surpass, and nothing is too difficult that you can't learn.
Skills
My primary objective as a Solidity Developer is to create gas-optimized and secure EVM smart contracts. I possess experience in developing various types of smart contracts, ranging from factories, ERC20s, ERC721s, and ERC1155s to staking mechanisms and crowdfunding contracts. Additionally, I am skilled in implementing proxy patterns like UUPS, beacon, and transparent proxies.
- Programming Languages: Solidity, Python, Javascript
- Smart Contract Development Frameworks: Foundry, Hardhat, Brownie
- Version Control: Git and GitHub
- Tests: unit tests, fuzz tests (stateless and stateful), static analysis
- Test Frameworks: Foundry, Slither, Echidna
