Paul Shynin

I build and modernize the backend and platform systems that revenue runs on: checkout, payments, catalog, and the migrations that move them onto better foundations without breaking production. Most of my work crosses team boundaries, usually because a migration touches checkout, catalog, payments, and on-call at the same time and someone has to hold the whole shape of it.

Over 12+ years across commerce, security, data, and healthcare, my depth is backend and integration architecture, with real reach into full-stack, platform, and reliability. In commerce I architected the services behind a checkout flow handling ~4K orders/week and led a reliability initiative that cut high-severity incidents ~85%.

On my own time I build agentic AI systems: multi-agent LLM orchestration and RAG. Away from the keyboard, I'm usually with my family or outdoors, hiking, kayaking, and playing sports.
