What I'm looking for

I’m looking for a role where I can build secure, cloud-native Java microservices and REST APIs, improve architecture for better performance, and deliver reliable products through strong testing, CI/CD, and continuous learning.

I’m a Systems and Informatics Engineering professional and software developer who learns quickly and delivers with punctuality, honesty, and responsibility. I’m committed to meeting expectations and improving systems through clear objectives, continuous improvement, and strong code quality.

My focus is backend development and cloud-native architecture: Java, Spring Boot, Spring Web/Spring WebFlux, Spring Data, and Spring Security. I build REST API microservices using SOLID principles, apply reactive programming, and strengthen reliability with unit/integration testing (JUnit/Mockito, Jest/Jasmine/Karma, Karate/Citrus) supported by JaCoCo and SonarQube.

I’ve worked on multiple banking projects building and evolving microservices and SPAs, managing vulnerabilities and technical debt, and integrating security with OAuth/Azure. I leverage AWS/GCP/Azure services (including EKS, Lambda, Step Functions, DynamoDB, CloudWatch) and modern CI/CD practices with tools like Maven/Gradle/NPM, Sonar, and CloudFormation—plus AWS Cloud Practitioner and AWS Solutions Architect certifications.
