PRD → IMPLEMENT → VERIFY → SHIP

From PRD to production.
Built with agentic workflows.

I'm Javier, a backend-leaning full-stack engineer. Each exhibit is real, deployed, and backed by GitHub activity, with the agent-driven process shown in full.

THE METHOD

A closed agentic loop, on every exhibit

Each product is built with a repeatable, verifiable pipeline, driven by a PRD and Claude Code skills, closed by automated checks.

Explore

Scan the repo, read context, frame the problem with the agent.

PRD

Write a PRD: scope, tasks, and acceptance criteria.

Implement

The agent writes code and tests against the PRD.

Verify

Lint, typecheck, Lighthouse, CI, then loop back.

iterate When verify fails, loop back to implement; Claude Design ⇄ UI runs on every visual change.
