Building scalable systems, AI-powered products, and digital platforms.


๐Ÿš€ About Me

Software Engineer focused on building scalable backend systems, reliable software architectures, AI-powered applications, and digital products.

I develop real-world projects while deepening my knowledge of Software Architecture, Domain-Driven Design, Cloud Computing, Distributed Systems, and AI Engineering.

My goal is to build software that is:

  • easy to evolve;
  • reliable in production;
  • well-tested;
  • scalable;
  • aligned with real business needs.

Current interests include backend engineering, SaaS architecture, LLM applications, AI agents, RAG, cloud infrastructure, and product engineering.

๐ŸŽต Beyond Code

When I'm not building software, I enjoy studying music production, sound design, and electronic music.

I believe engineering and creativity complement each other: both involve understanding systems, experimenting with ideas, solving problems, and transforming concepts into meaningful products.


Building software. Learning continuously. Turning ideas into products.
