Mobile app integrated with MetaMask
I developed a mobile app in React Native (without Expo) that connects to the MetaMask mobile app using Ethers.js and the MetaMask SDK. The user can interact with the lottery smart contract (see below) directly trought the app. To pay for a transaction, the app automatticaly redirects to the MetaMask app for the user to approve the transaction with its preferred wallet and gets redirected back to the app.

React website to place bets on an Ethereum lottery
I built a website usign React and Material UI to interact with a lottery I built on blockchain (see below). The website connects with a browser wallet and let the user place bets on the lottery. The system also counts with a serveless bakcend to keep record. The backend is on Google Cloud Plataform.

Smart Contract written in Solidity
I created an Ethereum lottery built with a smart contract. The contract follows the most safe security protocols and manages the draws whitout human interference. Entries are open for a week, users pay a fee to enter, this value goes straigth to the contract address, and, on the day of the draw, the contract calls for random numbers to ChainLink VFR. The contract then selects the winner and transfers the value to them.

A DEX to buy and swap ERC-20 tokens
I built a decentralized exchange for crypto. You can buy and/or swap your tokens at cryptoswap.com. I leveraged the 0x api, wagmi and the Alchmey SDK to built the whole infraestruture to interact with a pool of tokens and their contracts. My DEX is safe, low gas, and my go to whan I need to swap tokens.

App and website for a luxury rental company
I developed this app during my tenure in IK Solution. It is a React Native with Expo app for a company that rents luxury itens. I built the whole UI after a Figma module made by the UI team. I also developed the availabillity check system and payment modules for the app. This app was published to both stores.

Starvy App, a mobile plataform for clients and restaurants
This was a startup that I founded and managed for a year. It was based on a mobile app that allowed people to search for restaurants, see the menu, and, once at the place, place the order and pay with their phone. There is also a web plataform for the restaurants to manage the orders.
