Marcelo Feliciano

Software engineer focused on designing, deploying, and operating production-grade systems in cloud environments.

I build reliable APIs and backend services with a strong emphasis on correctness, predictability, and operational simplicity. Most of my work is centered around AWS-based architectures, making explicit trade-offs between performance, cost, and risk.

I favor simple, well-understood solutions that are easy to reason about and operate in production.


Core Stack

  • Languages: Java (primary), TypeScript / Node.js, SQL
  • Frameworks: Spring, Angular 2+
  • Databases: PostgreSQL, MongoDB
  • Cloud & Infrastructure: AWS, Docker, Git, Maven

Engineering Principles

  • Clarity over cleverness
  • Proven technologies over novelty
  • Measure before optimizing
  • Production is the source of truth
  • Systems are designed assuming failure

Shipping working software is only the beginning. Keeping it running is the real job.
