Making DHIS2 analytics fast enough to actually use.

01 — IndicatorX

Big DHIS2 reports, without the big wait.

IndicatorX is a faster engine that runs underneath DHIS2, built to speed up its heaviest reports — the program indicator analytics that large Tracker programs rely on but normally dread running.

The result: program indicator analytics that used to take most of a working day now finish before your coffee's cold.

~8h → ~40mProcessing time, large tracker programs
Old way~8 hours
IndicatorX~40 minutes
Same report, same data — just faster to run.
02 — AnalytiX

Ask your DHIS2 data a question. Get a straight answer.

AnalytiX lets you ask questions about your health data in plain, everyday language — the way you'd ask a colleague. No report builders, no filters to configure, no technical training needed.

It works for both individual patient questions (like TB or child health cases) and facility-level indicators, and it only ever answers using the data you're already allowed to see in DHIS2.

What we build

Five systems, one data layer.

Every engagement draws on the same core capability: turning fragmented health data into something a decision-maker can act on in real time.

Core

DHIS2 Implementation & Tracker Systems

Configuration, customization, and large-scale Tracker deployments across national and multi-country programs.

Surveillance

Disease & Early Warning Surveillance

Case-based surveillance systems for TB and other diseases, plus One Health workflows linking animal and human data.

AI / Analytics

AI-Powered Analytics Tools

Natural-language and high-performance analytics engines purpose-built for DHIS2 data — AnalytiX and IndicatorX.

Public sector

Disaster & Emergency Management Systems

Extending DHIS2's data architecture into disaster management ecosystems for provincial authorities.

Climate

Climate & Health Systems

Bringing climate and weather data into DHIS2 to track and forecast climate-sensitive diseases — dengue, malaria, heat and flood-related illness — with early warnings for health authorities.

Where the expertise comes from

Built on real-world DHIS2 delivery.

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.

TB Case-Based Surveillance

Tracker Data Export Service, PPM doctor integration, and an AI-powered case-based query tool for a multi-year TB surveillance program.

Zubair Asghar

Founder & CEO
  • 2015–2026Solution Architect, HISP Centre (DHIS2), University of Oslo
  • 2007–2014Integration Consultant, Ericsson — Pakistan, Iraq, Iran
  • EducationMSc Programming & Networks, University of Oslo · BSc IT, NUST

Zubair spent more than 10 years at the University of Oslo's HISP Centre — the home of DHIS2 — as a solution architect and core platform developer. He is the 3rd-highest code contributor to the DHIS2 core platform, working on its backend services, the Tracker data model and the analytics engine, and helping move the platform from a monolith towards a semi-microservices architecture.

On the implementation side, he designed and developed Pakistan's national TB surveillance system, used across government and private-sector facilities, and the HMIS for Gilgit-Baltistan. He led the HISP Pakistan engineering team, setting technical direction for systems delivered to Mercy Corps, UNICEF Pakistan and provincial government departments — including multi-country TB surveillance, EMR, community health worker and One Health initiatives.

Integration has been a constant thread: connecting DHIS2 with other health systems through HL7 v2 and FHIR, building listeners that turn incoming messages into data for DHIS2's APIs, SMS modules for reliable data collection, and an Nginx/Lua middleware layer that enforces data rules across a multi-country deployment.

Earlier in his career, he worked as an Ericsson integration consultant in Pakistan, Iraq and Iran, building real-time charging, billing and number portability systems for mobile operators — high-volume systems where downtime is not an option. That telecom-grade discipline shapes how he builds health systems: robust, high-performance and designed to keep running at national scale.

That core-level knowledge is what TerraByte is built on: from large-scale Tracker programs and TB case-based surveillance to performance engines like IndicatorX and AI tools like AnalytiX, every system we build starts from a deep understanding of how DHIS2 works underneath.
