MILC Group builds technology for dairy operations, combining its own hardware (scales, sensors and gateways) with a cloud platform and training. Its flagship product, ONE, connects feeding, facility monitoring, herd management, weighing and team management in a single system, localised into five languages. CodigoDelSur was MILC Group's software partner for nine years, building and running everything above the device.
Four requirements pulled against each other. A dairy's most valuable data is captured exactly where connectivity is worst, so the field apps had to keep working with no network. Many dairies, each with full crews across shifts plus outside vets and nutritionists, work against the same live dataset. Every sensor reading and every weigh is kept forever. And ONE launched with one module, then had to absorb whole new domains without destabilising what was already running on real farms.
CodigoDelSur built and ran the whole platform: the backend, the web applications, the native Android and iOS apps, the AI assistant and the training platform. MILC Group built the hardware and its firmware; everything above the device was CodigoDelSur's. The field apps are offline-first over a local database that syncs when connectivity returns, and talk to the hardware directly over Bluetooth. Stack: Node.js, TypeScript, PostgreSQL, Redis, AWS, React, Kotlin, Swift.
Nine years in production, with a team that grew to 40 people, around 25 repositories, 110,000 commits and roughly 3 million lines of code. Five business domains were delivered end to end, Feed, Facility, Animal, Scale and People, each large enough to be a product on its own. ONE launched with Feed alone and absorbed the other four with no rewrite and no pause in delivery. The engagement closed with a full handover to MILC Group's in-house team, platform live.
