Seven builds between January and August 2026, each answering a question the last one raised. Six are still online.
One question: if you put solar on your roof, does the money work? Cost, loan repayments and monthly cashflow on a single screen — nothing else.
The numbers alone weren’t enough. Assessment, marketplace, financing, contracts and monitoring joined the calculator, and it started to resemble a product.
Solar isn’t one person’s job. Homeowners, dealers, operations and admins each got their own signed-in view. Two rounds of feedback landed here — the ISJ2 record splits them as 3A and 3B.
The move to Google Cloud. Bill scanning, Solar Scout, dealer quote generation and a live energy dashboard, on a real cloud backend rather than serverless functions.
Two installable apps sharing one core: a customer app that takes a bill and returns a readiness answer, and an installer app that works a queue of leads. Now at version 1.1.3.
A full rebuild in Flutter: one shared feature layer behind web, admin and mobile. It replaced the previous web app in place, and was itself replaced five days later.
One role-routed app that walks each person end to end: homeowners from signup through assessment, savings and quote to a matched installer; installers from verification through quoting to installation. English and Filipino, read-aloud, WCAG AA. Now at v2.2.0.
