What I'm looking for

I'm available for fully remote work across LATAM, on a full-time or contractor basis.

At Globant, I work on backend transformation and modernization for financial institutions and insurance companies, combining architecture with hands-on Java development. I design Java 17/21 microservices with Spring Boot and REST APIs.

I define architecture criteria for service boundaries, API contracts, persistence, caching, and synchronous and asynchronous integration. I also analyze existing code and repositories to identify dependencies, technical debt, quality risks, and migration opportunities.

For enterprise applications, I design identity and access solutions with Keycloak, CIAM, OAuth2, OpenID Connect, and JWT. My earlier work included microservices for BCP digital transformation at everis (actual NTT DATA), and enterprise platforms across energy, banking, and insurance.
