Node.js / TypeScript / Go / AWS / Distributed Systems
I build dependable backend systems for commerce, SaaS, and operational platforms, with a focus on event-driven and serverless architecture, search, and observability. Lately, I've also been building AI agent systems — from Junando, an open-source alert-correlation agent, to AI-assisted engineering workflows in my day-to-day work.
Implemented backend components for a telecom client's serverless eSIM activation solution using Go and AWS services (Lambda, Step Functions, DynamoDB, among others), along with its delivery pipeline.
Co-designed state machines for activation workflows and implemented their integration.
Migrated technical documentation from Drive to Confluence for better indexing by Rovo and Claude Code embeddings, and created language-agnostic skills for AI-assisted engineering workflows.
Found and fixed a bug in the provisioning service's Go migration library, flagged via Sentry.

Cencosud
Senior Backend Engineer
Helped build cenco-pim-config with NestJS and hexagonal architecture for the Cenco PIM ecosystem.
Implemented CQRS with MySQL writes and denormalized OpenSearch reads for catalog workloads, plus an SQS-to-OpenSearch error indexing pipeline with rotating indices and ISM policies.
Defined Kubernetes deployments and container hardening after Trivy audits; administered GitHub Actions workflows on self-hosted autoscaling runners.
Built testing harnesses and quality tooling used across the platform team's delivery.

Steplix
Senior Backend Engineer
Worked in a support role focused mainly on observability — monitoring and alerting with CloudWatch and X-Ray for a telecom eSIM activation platform.
Migrated caap.aero (Corporación América Airports) from WordPress to Next.js 16 — Lighthouse scores of 96 Performance, 87 Accessibility, 96 Best Practices, 100 SEO.
Maintained the Mi Alarma X-28 mobile app (React Native) — 50k+ downloads on iOS and Android.

Tiendamia
Senior Backend Engineer
Migrated critical backend APIs from PHP/Magento to Node.js, improving API response times by ~60%.
Integrated the backend with Amazon SageMaker and OpenSearch for hybrid search, including vector generation and storage, and selecting traditional or semantic search based on query length; contributed to the surrounding system, not model training.
Implemented CQRS with DocumentDB read replicas, RabbitMQ event messaging, Redis caching segmented by market, and domain-driven design.
Published reusable Node.js packages to npm (a database connection client, a logging utility) used across multiple internal projects.

Personal open-source project
Junando
AIOps alert correlation agent that groups and enriches monitoring alerts with LLM analysis, delivering actionable incident context to Slack or Teams.
Hexagonal architecture: a webhook Lambda validates and queues events; a worker Lambda runs the full enrichment pipeline.
Alert deduplication by fingerprint with Redis, dead-letter queues, and infrastructure as code with AWS CDK.
Swappable LLM provider (Gemini, Claude, OpenRouter) behind a ports-and-adapters design — provider changes in minutes.
TypeScript monorepo, Vitest test suite, Docker/Kubernetes support with Helm charts, Apache 2.0 licensed.
