I am a frontend and full stack software engineer with over seven years of experience building scalable web and mobile applications. My core expertise includes Angular, TypeScript, React, Ionic, and Tailwind CSS.
I have led legacy modernization initiatives, including migrations from AngularJS and CoffeeScript to modern Angular and TypeScript architectures. I focus on improving application reliability, maintainability, performance, and long-term scalability.
I build high-quality user interfaces with attention to accessibility, responsive design, and UX principles. I have implemented W3C accessibility support and created dashboards that make complex government, energy, and business data easier to understand.
I also have experience with backend integrations, Supabase, AWS Lambda, CI/CD pipelines, automated testing, and release workflows. I use tools such as Jest, Testing Library, Playwright, GitHub Actions, and GitLab CI to deliver robust software.
In my current role, I develop a natural gas trading application with real-time buyer-seller matching and notifications. I collaborate on requirements, validate business workflows, and rapidly deliver prototypes for market validation.
I hold a Bachelor's degree in Computer Science from the University of Brasília and am motivated by building reliable products that solve real business and user problems.
Develop a natural gas trading application with real-time matching between sellers and buyers, instant notifications, and Supabase backend services. Delivered a functional prototype for market validation in under three weeks using React and AI agents.
Refactored the codebase to improve maintainability and quality. Implemented unit tests with Testing Library and end-to-end tests with Playwright, while collaborating on requirements and business workflow validation.
Migrated a legacy AngularJS and CoffeeScript payment system to a modern Angular and TypeScript stack, improving reliability and maintainability. Implemented automated unit tests with Jest and Testing Library to support system stability after the migration.
Integrated legacy and modern systems to maintain uninterrupted operations during the transition. Rebuilt and optimized POS modules, improved user experience and scalability, and implemented components aligned with W3C accessibility standards.
Architected a browser-based desktop environment in Angular with modular mini-applications. Applied SOLID and Clean Architecture principles to support scalability and maintainability.
Introduced Jest unit testing, GitHub Actions CI/CD workflows, environment configurations, and linters to improve development velocity and enforce code quality. The project was discontinued due to the pandemic.
Developed the frontend architecture for an electric energy data dashboard using Angular, reusable UI components, and real-time data visualization. Led a gradual AngularJS-to-Angular migration using integrated environments and Webpack bundling.
Built a PDF-generation microservice with AWS Lambda and implemented GitLab CI pipelines to streamline deployments. Also launched an Ionic mobile application for invoice payment and data monitoring.
Developed a mobile-first dashboard that simplified access to government data for the general public.
Applied UX principles to improve data discoverability, clarity, accessibility, and user engagement.
Led the design and development of an energy-consumption analytics dashboard for enterprise clients.
Used Angular and UX techniques to improve usability, responsiveness, and the ability to monitor and reduce energy costs.
Created an Angular single-page application for managing internal military administration data.
Applied UX best practices to make the system easier to use and improve internal data-management workflows.
