I build Go backend services, REST APIs, and secure customer journeys.
PortugalWhat I'm looking for
I'm developing Go backend services at DEUS AI for embedded customer journeys across US and UK markets. I design REST APIs from OpenAPI/Swagger contracts for identity, account linking, and frontend-facing journeys.
I apply Hexagonal Architecture to separate domain logic from third-party APIs, Auth0/CIAM, Redis, and loyalty integrations. I've implemented OAuth 2.0 flows, social login, email OTP verification, eligibility checks, and customer account linking with Redis-backed sessions and challenges.
Previously at CITEVE, I developed and maintained REST APIs connecting internal modules and industrial systems. I built Go backend features with clean architecture, Keycloak OIDC authentication, SeaweedFS object storage, and data pipelines using PostgreSQL, MongoDB, InfluxDB, and Kafka.
I'm comfortable delivering in Agile and Kanban teams using GitHub, CI/CD, code reviews, SonarQube, Docker, Linux, Jira, Miro, and Azure DevOps.
