BackEnd Engineer at Falabella
Santiago, Santiago Metropolitan Region, Chile
Summary
👤
SeniorJaime Hernández is a backend and AI engineer with nine years of experience building production-grade systems that connect LLMs to real business workflows. He combines cloud-native microservices (Golang, FastAPI, GCP BigQuery, Pub/Sub, Kubernetes) with advanced AI patterns—multi-agent orchestration, persistent memory, and hybrid RAG pipelines—to deliver scalable automation rather than prototypes. As founder/CTO of CodeIA.cl and a current backend engineer at Falabella, he has shipped domain-tuned solutions like a 31K+ chunk hybrid RAG for maritime diagnostics and an AI video editor pipeline. Jaime’s toolkit spans fine-tuning LLMs (LoRA/QLoRA), workflow automation with n8n, and observability with Grafana/Datadog, reflecting a pragmatic focus on reliability and real-user impact. He’s based in Santiago and often bridges product, research, and engineering to move experimental AI into audited production.
