What I'm looking for

I seek roles where I can lead development of production LLM systems in LegalTech, focusing on reliable, auditable AI, cross-functional product work, and cloud deployments with strong growth opportunities.

I am an AI Engineer and Full Stack Developer with a cross-functional background in Law, Business, and Blockchain, focused on building production-grade LegalTech solutions that combine fine-tuned LLMs with deterministic software to ensure precision at scale. I led the AI architecture for HerenciasOnline, delivering OCR pipelines with >95% entity extraction accuracy and process automation that cut Time-to-Resolution from 3 hours to under 10 minutes.

Former litigator turned builder, I bring stakeholder management, client-facing experience, and pragmatic problem-solving to technical product work; I design system and product architecture, implement LLM fine-tuning and RAG systems, and deploy cloud-native services on Microsoft Azure to ship reliable, auditable AI products.
