Full-Stack Developer at Esfera Crítica

February 1, 2026 - July 1, 2026

Worked on an established stack including PHP, MySQL, React and TypeScript, migrating a legacy system to a modern architecture across multiple product modules. Built and integrated REST APIs for authentication, user management and role-based permissions, improving and stabilizing the existing PHP backend rather than rewriting it from scratch. Owned features end-to-end, from implementation to refactoring, improving code structure (UI, business logic and services separation) and long-term maintainability. Contributed to technical discussions on architecture and code quality, proposing improvements for the legacy codebase.

Web Developer (Freelancer) at Independent / Web Developer

January 1, 2024 - Present

Designed, built, and maintained web applications and e-commerce platforms end-to-end using React, TypeScript, and Next.js. Implemented Next.js API routes (Node.js) and backend logic in PHP. Built and consumed REST APIs, integrated third-party services (payments, AI, and external data APIs), and managed MySQL/PostgreSQL databases. Used AI-assisted development tools daily (GitHub Copilot, Cursor AI, Claude Code) for faster implementation, testing, debugging, and documentation—reviewing outputs for correctness and quality. Owned projects independently from requirements to deployment, adapting to new stacks and client needs.
