About Me
I'm João, a brazilian software engineer passionate about backend and full-stack development. I've helped build secure payment systems, compliance solutions, and enterprise-grade HR and payroll applications — always aiming for clean code, scalable architecture, and real-world impact. I enjoy working across the stack, especially when cloud platforms and microservices are involved.
When I'm not coding, you'll usually find me exploring new coffee spots, traveling to experience new cultures, or relaxing at home with my dogs. To stay balanced, I practice Muay Thai, and for fun, I enjoy playing racing sims.
