Work Experience

Senior Full-stack Developer

2022 - PRESENT
MJV Innovation
  • Integrated AI-assisted development into the development lifecycle with tools such as GitHub Copilot and Gemini, leveraging agents to accelerate legacy migrations and configure comprehensive test suites, as well as creating Angular frontends.
  • Promoted AI-assisted best practices, driving agent-guided code review processes using GitHub Copilot to ensure alignment with microservices architecture and security standards.
  • Migrated a monolithic architecture to a microfrontend architecture using Module Federation and Angular, allowing developers to work independently.
  • Improved front-end performance by implementing asynchronous module loading in Angular, reducing the 1st render.
  • Designed and implemented comprehensive automated test suites with JUnit and Mockito for Java applications, achieving over 90% code coverage across the majority of system components.
  • Developed and maintained scalable microservices with Java, Spring Boot, and Node.js, integrated with databases such as Oracle SQL and MongoDB.
  • Modernized legacy systems by migrating from technologies such as JavaServer Pages, JavaServer Faces, and jQuery to Angular.
  • Enforced asynchronous communication using RabbitMQ to schedule report generation, avoiding performance issues caused by synchronous data processing overload.
  • Implemented report generation in formats such as PDF and XLS using Java and libraries such as Apache POI and JasperReports.

Experience

Planning Poker Application – AgileEazy

https://agileeazy.com/
Planning Poker, also known as AgileEazy, is a web application I developed to help Agile teams estimate project tasks more effectively. I engineered the entire full-stack architecture, focusing on a seamless user experience for remote collaboration.

On the front end, I used Angular to build a responsive interface that supports internationalization in English, Portuguese, and Spanish. To ensure all team members see voting updates instantly, I integrated real-time communication using WebSockets.

The back end is powered by Node.js and Express.js, utilizing MongoDB for flexible data storage. I also implemented a secure authentication system using Passport.js and JWT, allowing users to sign in via email or social accounts like Google and GitHub.

By delivering this project from concept to production, I created a scalable tool that simplifies software development team estimation.
