Backend-Focused Fullstack Developer · Java & Spring Boot

I’m a backend-focused software developer specializing in Java, Spring Boot, and microservice architecture. I build REST APIs, authentication systems, and distributed services with a focus on clean architecture, scalability, and maintainability.

Currently pursuing my 4th year of IT at ACLEDA University of Business and trained in Spring Microservices at ISTAD.

Backend Java · Spring Boot · Spring Cloud · Spring Security · REST APIs · JPA / Hibernate

Architecture Microservices · DDD · CQRS · Event-Driven Architecture · OAuth2 · JWT

Data & Messaging PostgreSQL · MongoDB · Redis · Apache Kafka

Frontend Next.js · React · TypeScript · Flutter

DevOps & Tools Docker · GitHub Actions · Git · Liquibase · Nginx · Postman
