Software Engineer

Hi. 👋

I'm Antônio Pataro, a Software Engineer from Brazil with 4 years of experience.

In 2020, I was an undergraduate student in Aerospace Engineering at UFMG, one of the most prestigious universities in Latin America. During my time there, I had my first contact with programming.

In 2021, I already couldn't help but learn as much as I could, as fast as I could, taking a leap of faith to drop out of college and pursue this career as a self-taught. Since then, I made my way into this industry, specializing in web development.

As a beginner, I enjoyed front-end. Later on, back-end became my passion. Now, full-stack development is my specialty ― mainly with Node.js and Go.

Here's a summary of my last work experiences.

2023 - Present

Fullstack Engineer, Smartrips

  • Maintained critical services on a travel-tech company, including core Node.js REST APIs, microservices written in Go (Golang), and multiple front-end platforms using Typescript, React (i.e., HTML, CSS, Javascript), and Next.js under an AWS cloud infrastructure;
  • Led a complete redesign of the main front-end PWA (Progressive Web Application) using React.js, Typescript, and Vite, taking the opportunity to add unit tests with Jest, improve observability with Sentry, and even design solutions for stakeholders with Figma;
  • Optimized analytics processing by migrating gigabytes of transaction data using ETL (Extract, Transform, and Load) strategies, creating a high-performance generation solution using Node.js streams and optimized SQL queries, significantly reducing the core MySQL database's write/read ratio;
2023

Front-End Engineer, Dinheirow

  • Contributed to a fintech company's front-end platforms, being responsible for maintaining Vue and Next.js applications written in Typescript;
  • Worked on the rewrite of the backoffice system from Vue to Next.js, creating unit tests with Jest for React.js components and hooks, experimenting with TDD (Test-Driven Development) as a culture, and documenting components with Storybook;
  • Maintained the team's Bitbucket Pipeline to ensure a reliable front-end CI/CD workflow, following established Git Flow practices;
  • Participated actively in the proposal of UI/UX design solutions for new backoffice features, using Figma to create prototypes for stakeholders;
2022 - 2023

Fullstack Engineer, Intelligix

  • Worked on a data protection and regulation company's MVP, focusing on the fast shipping of a core Express.js GraphQL back-end and of a main React.js platform, both written in Typescrip;
  • Created an internal company library while developing the front-end with React.js, Typescript and Vite, designing Figma mockups before each task at hand;
  • Had the opportunity to write the system's authentication and authorization flow from scratch using NestJS, managing multiple entity types with a multi-tenant MySQL database;
  • Implemented a queue mechanism on the core API with RabbitMQ to dispatch email templates designed with React Email;
2021 - 2022

Fullstack Engineer, Em Suma

  • Created a linear regression statistics model using SciDAVis that evolved into a Go (Golang) microservice, laying the foundation for the birth of an educational platform;
  • Designed the system's architecture from scratch on AWS, using services like CloudFront, Comprehend, ElasticCache, RDS with PostgreSQL, S3, SQS, Textract, and even Lambda to host an entire Clean Architecture Node with Express.js API - effectively, eliminating server costs;
  • Built white-label systems for schools and applications for students and teachers using Typescript, React.js, and React Flow, creating an internal component library shared between projects while following front-end Clean Architecture and TDD (Test Driven Development) principles;
  • Integrated extensively with third-party providers, such as MercadoPago (payment gateway), Resend (mailing), LanguageTool (grammar checker), and, later on, even OpenAI's ChatGPT for generating an AI summarized revision of essays;
