 Full Stack Developer

Paulo Jerônimo is a Software Developer. He has acted in the corporate market since 1993. For several years, he has preferred using open-source platforms and programming languages. In his latest work, he has focused on building Decentralized Applications (DApps) for Web3. He has applied agile methodologies and practices since he participated in the event "Extreme Programming Brasil 2002". From 2017 until today, he has published content about Blockchain and Ethereum. Working at his Startup, he develops innovative solutions for the wellness area and offers to mentor on Web3 technologies. He actively participates in events in this area. Regarding technologies for building Web3 solutions, his most significant experience is, in the backend, in the use of Solidity languages (applied to the development of Smart Contracts) and JavaScript (through Web3.js or Ethers.js APIs). He has experience creating Fungible and Non-Fungible Tokens (NFTs) following standards such as ERC-20, ERC-721, and ERC-1155. To obtain lower transaction fees for DApps, he programs solutions using Polygon's Blockchain or BNB Chain. In building frontends, he is most familiar with using JavaScript, React, and Next.js. But, he also made use of TypeScript, Svelte, and SvelteKit. About tools for EVM based Blockchains: he has experience using Remix, Truffle, HardHat, OpenZeppelin, Moralis, and others. He has experience in Rust development for the creation of Smart Contracts for the NEAR Blockchain.

Paulo Jerônimo has worked as a Technical Leader, Software Architect, Backend Developer, and on some occasions, as an DevOps and Site Reliability Engineer. In addition, due to his extensive experience with test automation (unit, integration, functional, and performance), he has the skills to work as a Test Analyst. ← The links in this paragraph point to the more generalized version of this curriculum.
