I'm building conversational AI and semantic-search capabilities at Mercado Libre for Chile's real-estate market. I developed a Go-based event-driven orchestration service connecting WhatsApp, n8n, GPT-4.1 mini, NoSQL, queues, follow-ups, and BigQuery, while owning production deployments through Fury.

At Webmotors, I architected an AWS Bedrock fraud-detection pipeline processing 200K+ daily messages, cutting spam from 50% to 5%. I also led a 20-year-old .NET monolith migration to NestJS microservices, reducing p95 latency from 30 seconds to 3 seconds and contributing to a 5–6% revenue increase.

Previously at Hyperlocal, I helped a six-engineer team deliver a production-ready AWS microservices digital banking platform in six months. I reworked payment processing into an asynchronous queue-based pipeline that reduced processing time by 70% and automated onboarding, credentialing, and payment workflows.

Across Banco PAN, Wunderman, SuMi Trust Global Asset Services, Cubic Telecom, and Itaú Unibanco, I've built and supported high-volume financial, telecommunications, and enterprise systems. I bring 17+ years of backend, cloud, distributed-systems, and technical leadership experience, including four years working professionally in Ireland.
