Luis Doriz

I’m a full-stack software engineer with 7+ years building production systems. I’m currently a founding engineer at an a16z-backed AI startup, shipping LLM-powered agent infrastructure end-to-end.

At Handle, I’ve owned end-to-end architecture, product engineering, and an engineering team—designing and shipping 4 core product modules from zero: system-of-record, AI-powered quoting agents, payment validation, and reconciliation. These modules generate recurring revenue from enterprise customers.

I built a tool-based LLM agent system processing 700K+ automated quoting transactions per month, integrating Selenium-driven carrier portals with structured tool-use over OpenAI/Anthropic models. I also architected a v2 job-based pipeline with optimized storage and shipped production integrations across carrier systems, Gmail/Outlook, WhatsApp, and Google Drive to enable end-to-end agent workflows.

Previously at Nowports (YC W19), I led data engineering efforts that automated 80% of manual data inputs using web scraping, ML-based extraction, and LLM-assisted classification—eliminating thousands of operator-hours per month. As a founding/early engineer, I helped ship core platforms that supported securing Series A, and later raised tracking coverage from 60% to 91% by refactoring ingestion and rebuilding the data-input UX.
