We design and build DHIS2-based health information systems, disease surveillance platforms, and AI-powered analytics for governments, NGOs, and international health programs.
IndicatorX bypasses DHIS2's service-layer overhead entirely — extracting the ProgramIndicator-to-SQL conversion logic and wrapping it as named PostgreSQL functions that run independently of the platform.
The result: program indicator analytics that used to take most of a working day now finish before your coffee's cold.
AnalytiX answers health-data questions in plain language — no SQL, no DHIS2 API calls, no manual period pickers. Time ranges are just typed in natural language and parsed straight into the query.
Underneath, it runs two independent pipelines depending on what's being asked: a Case-Based pipeline, where an LLM generates SQL against a locally synced DuckDB/ClickHouse copy of tracker data for patient-level questions (TB, child health, etc.); and an Aggregate pipeline for facility-level indicators, also LLM-driven, but with data elements picked from an explicit chip/browser UI rather than extracted from free text. Every answer is also scoped to the org units the asking user is actually permitted to see in DHIS2, enforced from their own login.
Every engagement draws on the same core capability: turning fragmented health data into something a decision-maker can act on in real time.
Configuration, customization, and large-scale Tracker deployments across national and multi-country programs.
Case-based surveillance systems for TB and other diseases, plus One Health workflows linking animal and human data.
Natural-language and high-performance analytics engines purpose-built for DHIS2 data — AnalytiX and IndicatorX.
Extending DHIS2's data architecture into disaster management ecosystems for provincial authorities.
TerraByte Systems is a new company — these are systems our founding team has designed and built prior to and outside of TerraByte, shown here as background on the kind of work we do.
Tracker Data Export Service, PPM doctor integration, and an AI-powered case-based query tool for a multi-year TB surveillance program.
A pitch and implementation roadmap for bringing DHIS2's data architecture into a provincial disaster management ecosystem.
A workflow connecting animal and human health data streams, with an 8-step implementation roadmap for early warning.
"Accelerating Program Indicator Analytics in Large-Scale DHIS2 Tracker Implementations" — submitted to the DHIS2 Annual Conference 2026.
Close to the DHIS2 core development and research community, where the platform originates.
On the ground with national HMIS operations and the government and NGO partners running these systems day to day.
