  "account": "Fish cages on Lake Victoria can lose their entire stock overnight when dissolved oxygen levels drop critically. Most farmers rely on experience, visual checks, and late phone calls for monitoring. To improve fish-cage farming intelligence, a team of five built KIVU, a lake-wide aquaculture and environmental intelligence platform. KIVU sits between the farmer's phone and the lake, providing real-time telemetry, an explainable AI risk engine, geospatial zone intelligence, and expansion suitability signals. The technology stack includes Go 1.22, Gin, sqlx, PostgreSQL 15, PostGIS 3.3, JWT, bcrypt, HTML/CSS/JS, and Docker Compose. The AI Risk Engine uses a rule-based approach to score risk levels based on dissolved oxygen, temperature, and turbidity thresholds, providing human-readable recommendations and optional SMS alerts. Geospatial data is stored using PostGIS, enabling accurate distance and containment calculations. KIVU consists of four levels: cage water quality telemetry, farm multi-cage overview dashboard, lake regional intelligence, and expansion site suitability. The project emphasizes explainability for farmers to understand why alerts are triggered. Lessons learned include the importance of transparency, the value of PostGIS, and the benefits of pairing for API and schema consistency. Future developments may include real sensor integrations, stronger ML models, multi-language SMS/ USSD, and a progressive web app.",

We wanted something better. KIVU is a lake-wide aquaculture and environmental intelligence platform we built as a team of five.
