About

John ZapantaSystems & AI Engineer

I'm a systems builder focused on AI-powered automation and data intelligence. Most of my work lives in the gap between a messy operational problem and a clean, dependable system that solves it — assistants that draft and decide, pipelines that pull and reconcile data, and dashboards that surface the one thing a team actually needs to act on.

I work end to end: scoping the problem, wiring the integrations, designing the data flow, and putting it in production with the guardrails to keep it running. The stack shifts to fit the job — LLM APIs and Python for the intelligent parts, Node and Next.js for the interfaces, headless browsers and APIs for the data — but the throughline is the same: turn repetitive, error-prone work into something that runs on its own.

Principles

How I approach the work

End to end

Scope the real problem, wire the integrations, design the data flow, ship it with the guardrails to keep it running.

Right tool, not favorite tool

The stack bends to the job — LLMs and Python for the thinking, Node and Next.js for the interfaces, browsers and APIs for the data.

Built to run unattended

A system that needs babysitting isn't finished. The bar is reliable, observable, and safe to leave alone.
