An industrial data visualization platform that provides interactive dashboards for monitoring FPSO equipment performance. The solution helps engineers track operational metrics, identify potential issues early, improve equipment efficiency, and reduce unplanned downtime through real-time insights and analytics.

• Implemented multiple interactive data visualization charts using Apache ECharts to improve monitoring and data analysis;
• Implemented workflow state management for the investigation entity, ensuring a structured and consistent process flow;
• Improved the team's code review process by promoting higher code quality and more efficient collaboration;
• Increased unit test coverage and added end-to-end (E2E) tests to improve application reliability and maintainability.

A modernization initiative focused on migrating a monolithic application to a microservices architecture. The project separated core services into independently managed repositories and enabled containerized deployments with Kubernetes, improving scalability, deployment flexibility, and development efficiency.

• Increased automated test coverage by adding and maintaining unit and integration tests, improving application reliability and reducing regression risks;
• Created and maintained Kubernetes manifests to standardize containerized deployments, simplify environment configuration, and support scalable application delivery;
• Separated services from the monolithic application into individual repositories, enabling independent development and deployment through Kubernetes;
• Supported the migration from a monolithic architecture to a microservices-based solution by contributing to service decomposition and repository organization.

A collaborative document management solution designed to enable multiple users to work on shared documents safely and efficiently. The platform provides real-time editing awareness, document locking, and synchronized updates to prevent editing conflicts, preserve data integrity, and improve team collaboration.

• Developed and maintained the front-end user interface, ensuring a responsive and intuitive user experience;
• Implemented collaborative editing safeguards to prevent users from overwriting each other's changes;
• Developed a real-time user presence indicator with avatars to display active collaborators editing the same document;
• Built a document locking and lock-release mechanism to prevent concurrent save conflicts;
• Implemented synchronized save propagation and automatic lock release to ensure a seamless multi-user editing experience;
• Worked closely with the backend team to support real-time collaboration features and ensure consistent document state across users.

A digital publishing initiative for one of Latin America's largest media organizations, introducing a new content channel powered by Google AMP Stories. The solution delivers immersive, mobile-first storytelling experiences, enabling readers to consume news and editorial content through engaging, high-performance interactive stories.

• Led front-end development, driving the implementation of key product features and ensuring high code quality;
• Delivered the project within an accelerated timeline, contributing to a record delivery schedule;
• Built a high-quality user experience that received strong approval from stakeholders and end users.
