ABOUT ME

Full-stack software engineer with experience designing, building, and modernizing complex web systems across backend, frontend, architecture, reporting, internal platforms, and data-heavy applications. I work with a senior engineering mindset: connecting implementation with product goals, clarifying trade-offs, improving service boundaries, reducing architectural debt, and building systems that are reliable, maintainable, and easier to evolve.

My experience includes financial and operational reporting systems, BFF APIs, multi-tenant flows, permission models, report generation and download pipelines, metadata tracking, Elasticsearch-backed observability, frontend modernization, automated testing, and legacy system refactoring. I have worked with Ruby on Rails, React, TypeScript, JavaScript, Elasticsearch, SQL, REST APIs, background processing, and service-oriented patterns, often operating across the full lifecycle from requirements analysis and architecture to implementation, testing, deployment, and production support.

I have also led the development of a full written test management platform used in the driver’s license process in Pará, Brazil. In this project, I was responsible for documentation, use cases, architecture, database design, Design System selection, frontend and backend development, and overall technical direction. The system evolved from a Proof of Concept into a production application, with planned event-driven architecture patterns to improve data normalization and system integration.

In another project, I contributed to a biometric registration and identification system with web, desktop, and mobile components. My work focused on frontend design, backend improvements, modularity, maintainability, and performance optimization, resulting in a significant improvement in the web component’s performance.

I am looking for opportunities where I can contribute as a senior engineer by combining architectural thinking, product awareness, technical depth, and hands-on delivery to build systems that solve real business problems and remain sustainable over time.
