About

Professional summary

I am a Full Stack Developer focused on building efficient, scalable web applications aligned with business needs. My core stack includes Java, Spring Boot, React, TypeScript, JavaScript, Python, and SQL databases.

I have experience developing e-commerce platforms, multi-tenant SaaS solutions, CRM systems, institutional websites, and lead-generation landing pages. I work across frontend and backend layers, designing REST APIs, implementing authentication, and building responsive user interfaces.

In my freelance work, I have contributed to omnichannel CRM solutions with messaging integrations, including WhatsApp, as well as catalog synchronization between platforms. I also develop real-time web applications using WebSocket communication between frontend and backend services.

I use PostgreSQL and MySQL for data persistence, modeling, and querying. I am familiar with Docker, Git/GitHub, Swagger, Postman, WSL2, JWT, RBAC, SOLID principles, software architecture, and LGPD considerations.

I also create automation and web-scraping solutions with Python, Playwright, and FastAPI to extract and process operational data. I am currently pursuing a Software Engineering degree and continue improving my backend and full stack development skills.
