Fly.io Spotlights DAT: From Concept to Scale in Record Time

Fly.io profiled DAT as an example of a small technical team achieving outsized impact on public-sector infrastructure. The piece details DAT's flagship field-operations platform for the Lahore Waste Management Company, which tracks activity and flags anomalies across a staff pool of several thousand employees, using WhatsApp as the primary interface for field workers.

On the backend, DAT runs a fully serverless stack built on Elixir, with Neon for the database, Upstash for Redis, CloudAMQP for queues, and Retool for dashboards, deployed across multiple regions to keep latency low for both field staff and back-office users.

The piece also covers DAT's work with the Government of Punjab Solar Project, where the platform helps forty contractors manage a large-scale tube-well solarization initiative supporting thousands of farmers across the province — handling document management, stakeholder coordination, and payment tracking across multiple approval stages.

Fly.io also highlighted DAT's use of scale-to-zero infrastructure: field operations run in shifts, and the system scales down to a minimal footprint during quiet periods before scaling back up automatically when traffic returns.
