FullTank
A community-driven fuel availability map built during Sri Lanka's shortage — crowdsourced station reports, multi-report verification, and a public map that helped thousands find fuel when information was the scarce resource.

The Problem
During Sri Lanka's fuel shortage, the scarce resource wasn't only diesel — it was trustworthy information. WhatsApp rumors and closed Facebook groups couldn't tell you which station still had stock, or whether that tip was two hours stale.
FullTank turned scattered reports into a public map: people marked what they saw, multiple reports strengthened a station's signal, and the country could look at one place instead of fifty group chats.
In a shortage, a map that updates from the crowd is infrastructure — not a side project.
The System
A public web map aggregates community fuel-availability reports. Stations surface status from verified multi-report signals so a single optimistic ping doesn't rewrite the picture. The product stayed intentionally simple: find fuel, trust the signal, move.

Margin Notes
- What worked: simplicity. People in a queue don't want onboarding.
- What I'd redo: stronger anti-spam on single-station floods without adding accounts.
- What shipped anyway: a public map when the country needed one.
