The story.
Voltafy is the flagship of the holding — the platform that the other three energy products all connect back to. It's what I'd want if I were an installer managing hundreds of systems or a household that refuses to accept vendor-friendly numbers. The interface is deliberately operator-first: keyboard-first where it matters, readable at 3am, and built so that the uncomfortable truth about a system's performance is the first thing you see, not the last.
The five phases, applied.
Every build under Juan Diaz LLC runs the same playbook. Here's how it ran for Voltafy.
01
Survey
Rode along with installers, sat in on owner calls, mapped every data source the Dutch grid exposes and every one it refuses to.
02
Blueprint
Designed the schema and the operator flows before writing a single line of product UI. Every screen maps to a decision somebody actually has to make.
03
Build
Shipped the platform surface, the live monitoring backbone, and the installer workspace. Fast, honest, unopinionated about which vendor you use.
04
Commission
Stress-tested against bad network conditions, partial outages, and the messy reality of mixed-vendor fleets. Nothing goes live until it survives the edge cases.
05
Operate
Tuning weekly. Shipping incremental improvements straight from installer feedback — this product only gets sharper the more it runs.
Built on.
