Daniel Alberto Bustamante

I’m a Backend Java Developer specializing in enterprise applications with Java 17–21 and Spring Boot 3. I focus on clean, maintainable solutions guided by Clean Code principles and SOLID.

In my experience, I design and implement REST APIs, build modular architectures, and develop microservices that integrate reliably with external systems. I also handle end-to-end database modeling and optimization across PostgreSQL and MySQL.

I’m comfortable taking services to production—deploying and maintaining them on AWS using EC2 and RDS. I support continuous modernization and evolution of backend systems to keep them stable, scalable, and aligned with business needs.

I bring an engineering mindset centered on automated testing (JUnit, Mockito) and improvement through iteration. I’m also actively expanding my skill set through advanced Java & Spring Boot, microservices architecture, and ongoing Generative AI & Prompt Engineering and Ethical Hacking & Cybersecurity learning.
