I'm Danny Mairena, an AI Systems Engineer and forward-deployed problem solver focused on building agentic, production-grade AI systems that automate complex, high-stakes business workflows. I own solutions end-to-end—from ambiguous problem spaces and executive discovery through architecture, implementation, deployment, and continuous improvement. I'm comfortable shipping fast, ruthlessly cutting scope when needed, and embedding AI deeply into real operational systems, delivering measurable impact and robust, scalable production deployments.…I'm Danny Mairena, an AI Systems Engineer and forward-deployed problem solver focused on building agentic, production-grade AI systems that automate complex, high-stakes business workflows.
