Lanny Rivero

I am a Backend Developer specializing in Java and Spring Boot, with experience in designing secure REST APIs, hexagonal architecture, DDD, and advanced authentication with JWT/OAuth2. I work by applying best practices such as Clean Architecture, SOLID, and TDD, always focusing on maintainable, modular, and well-tested code.

I have developed complete projects such as:

• Spring Security Template: a professional template based on Nimbus JOSE + JWT, with roles, scopes, policies, integration with Keycloak, and clean architecture. It includes integration tests and modules designed for microservices.

• RenewSim: energy simulation platform following Hexagonal Architecture and DDD. It contains calculation modules, integration with external APIs, technology analysis, data visualization, and advanced business logic.

• Eureka Vending (business project): backend for a real smart locker system developed with Spring Boot, JPA, security, access control, and layered architecture.

• Revive (Finalist of the National Hackathon of Globant): web platform for buying and selling second-hand items, developed with Java, REST APIs, and secure authentication.

Additionally, I have experience in test automation with JUnit, Mockito, Cypress, Selenium, and Testcontainers for isolated environments and microservice testing.

I am characterized by technical clarity, fluid communication, and commitment to software quality. I aim to contribute clean, stable, and scalable solutions in every project.
