Hanniel Vieira

Hello! My name is Hanniel. I'm a Full Stack Software Engineer passionate about building scalable, high-performance applications and solving complex architectural problems.

I’ve been writing code since I was 15, accumulating around 4 years of practical experience. While my foundation is deeply rooted in robust backend systems, I actively build complete solutions from the database up to modern, responsive frontends.

  • 🏫 I'm currently studying Systems Analysis and Development at Mackenzie.
  • 🏗️ Focused on software architecture, high-concurrency systems, and DevOps practices.
  • 📚 Actively studying System Design concepts to improve my architectural decisions.
  • 💡 Always exploring new tech stacks and active in technology communities.

💻 Tech Stack & Tools:

  • Backend: Java 21, Spring Boot, Spring Security, Node.
  • Frontend: TypeScript, React, Next.js, Tailwind CSS.
  • Database: PostgreSQL, MongoDB, JPA / Hibernate.
  • DevOps & Cloud: Docker, Google Cloud, Nginx, MinIO.
