Software engineer at Asaru Seguros who developed Go and Node.js microservices with gRPC and NATS.

Colombia

Message

At Asaru Seguros, I developed backend services in Go and Node.js and designed and supported a microservices architecture using gRPC and NATS. I also integrated authentication and authorization with Keycloak.

I applied DDD and layered architecture as team-wide standards, and supported backend developers through code reviews and technical guidance. I deployed services on AWS with CI/CD pipelines and added observability with Prometheus and Grafana Loki.

At Laburu Agency, I built the complete CutePets storefront on VTEX IO. I also developed reusable features for Shopify and VTEX and integrated REST APIs for product, inventory, and promotion synchronization.

Across frontend roles at FincaRaiz, AuditBrain, Imexhs, and Ciao Soft, I developed applications and interfaces with React and Next.js. My work also included migrating a codebase to TypeScript, building forms with React Hook Form, and developing REST APIs with Node.js.
