What I'm looking for

I’m looking to grow as a full-stack developer, learning from more experienced professionals.

At Herculano Mineração, I developed an integration between Fluig and TOTVS RM using SOAP services and SQL Server for product registration and diesel write-off workflows. I also automated processes with n8n and webhooks, and investigated incidents in corporate systems.

For my Barbearia project, I built a full-stack appointment application with a Node.js and NestJS API and a React front end. I implemented asynchronous processing with RabbitMQ, safeguards against duplicate bookings, and automated tests and CI.

I also developed REST APIs with Node.js and TypeScript, including a URL shortener using Redis caching and a personal finance API. I’m looking to grow as a full-stack developer by learning from more experienced professionals.
