I build backend systems with Node.js, TypeScript, Go, and AWS, focusing on event-driven and serverless architecture, search, observability, and developer enablement. My applied AI work includes integrating hybrid search with Amazon SageMaker and OpenSearch, plus AI-assisted engineering workflows with the Gentle AI ecosystem (Engram, Spec-Driven Development, Orca). I work on the surrounding systems and workflows, not model training.

Contributed to state machine design, workflow integration, and developer enablement; found and fixed a Sentry-flagged bug in the provisioning service's Go migration library.
- Cencosud: Helped build a NestJS backend with hexagonal architecture and CQRS, MySQL writes, OpenSearch reads, Kubernetes deployments, and GitHub Actions workflows.
