About

Professional summary

I am a Frontend Software Engineer with more than four years of experience developing and evolving digital products using React, TypeScript, JavaScript, and Next.js.

I currently work at Grupo BYX, contributing to financial applications involving credit, cards, formalization, payroll loans, portability, and refinancing. I participate in the full development lifecycle, from technical refinement and solution definition to implementation, testing, code review, documentation, delivery, and production support.

My experience includes frontend architecture, microfrontends, design systems, componentization, BFFs, REST API integrations, asynchronous data management, automated testing, and technical documentation. I also contribute to architectural decisions, engineering standards, incident investigation, application stability, performance, and quality improvements.

I use artificial intelligence tools daily in my engineering workflow, including GPT, Claude, and Codex, for problem analysis, solution exploration, implementation, debugging, code review, testing, and documentation. I develop AI-assisted and AI-native workflows while maintaining technical ownership and validating all deliverables.

I am deepening my knowledge of software architecture and AI engineering, including LLMs, AI agents, RAG, MCP, AI system evaluation, and machine learning fundamentals. I value collaboration with Product, Design, Backend, and other technical teams to build maintainable and high-quality user experiences.
