Juan Pablo Lozano Ruiz

Co-Founder & CTO, Tynkr

Juan Pablo works at the intersection of data engineering, AI, and product engineering. Over the last four years he has designed and shipped systems across the full stack — from data pipelines and Power BI dashboards to Next.js applications, LLM-powered workflows, and large-scale Playwright deployments.

At Tynkr he leads the technical architecture: the execution engine, CI/CD pipeline design, AI-assisted test generation, OCR-based evidence capture, and the integrations that connect QA results to the tools engineering teams already use.
