What I'm looking for

I'm looking for a back-end development role where I can build REST APIs and production systems with Java and Spring Boot, deepen my work with clean architecture and DevOps, and continue growing through hands-on engineering challenges.

I built a production-ready quotation system with a Node.js, Express, and SQLite REST API, including six endpoints, JWT authentication, role-based authorization, Docker containers, and Cloudflare Tunnel deployment.

I'm actively transitioning into back-end development with Java and Spring Boot. In Delivery Eats, I expanded a Spring Boot delivery application while deepening my work with Spring Data JPA, Spring Security, layered architecture, and object-relational mapping.

Previously, I developed and optimized web interfaces at Sitecontabil, integrating external APIs with JavaScript and TypeScript. I also completed a postgraduate degree in Software Engineering and bring practical experience with AWS Serverless, Clean Architecture, DevOps practices, and front-end development.
