About this gig

Need microservices built the way they do it in enterprise banking? That's exactly what I deliver.


I'm a Senior Java Developer with 5+ years building microservices for banking clients like Bancolombia, Banistmo, and Ticketmaster. I bring that same engineering rigor to your project.


What I built:

REST API microservices with Java Spring Boot (Web, Data, Security, WebFlux)

Reactive programming with Spring WebFlux when performance demands it

OAuth2 / JWT security is properly implemented

PostgreSQL, MySQL, or MongoDB integration via Spring Data

Unit tests with JUnit + Mockito (JaCoCo coverage reports included)

SonarQube-clean code, no shortcuts on quality

AWS deployment: EKS, Lambda, or Elastic Beanstalk


Architecture: SOLID principles, clean code, design patterns always.
