Software, data and AI — from one design.
Expert Group is a senior-led engineering partner from Belgrade. We design applications, data platforms and AI as one system — and run them in production: a HIPAA-compliant EHR for 50,000 users in the US, clinical analytics with 1,933 certified measures, a sovereign AI inside a government ministry. Nine countries, one delivery team.
Three problems. Three answers.
Enterprise clients rarely lack tools. They lack connected systems, trusted data, and fast decision cycles.
Scattered reports
Excel files, several BI tools, PDFs in email — every meeting starts with an argument about whose number is right.
A reporting platform
Power BI embedded in your portal, one data model, certified measures — and an AI that answers from the same model.
Reporting as a Service →Manual operational work
Planning lives in Excel and email, and the ERP holds data the shop floor never sees. Production shows up two days late.
Custom software and integration
Scan-on-the-line tracking, shipment planning, a service bus to your ERP — processes that run themselves, in real time.
PROEE100 →AI pressure, data under lock
The board wants AI, and the data may not leave your network. Your customer's security review is waiting for answers.
AI on your terms
Four deployment postures — from Azure SaaS to fully inside your network. We passed a tier-one bank's vendor security review.
Security and AI →Products already running in production.
We do not sell slides. Every product came out of a real project and runs at clients today.
Reporting as a Service
Power BI embedded in your portal, a centralised data model and talk-to-your-data — a production-ready platform for CFO, COO and CIO teams. Microsoft Fabric, several companies in one instance, your branding.
Learn more →PROEE100
Production tracking and delivery planning, natively integrated with NAV/Business Central. Power BI included.
ProTax Manager
For groups with Serbian entities: property-tax filing as SaaS — returns prepared automatically through to XML for the LPA portal, backed by 30+ tax experts. Lidl Serbia, Wacker Neuson and MK Group file through it.
Power BI AI Assistant
An AI assistant over your Power BI model — local inference, deterministic DAX, data never leaves your network.
AI Agents
The Reporting Agent queries your Power BI model and shows the query it ran. The Assistant Avatar answers from your documents, with citations. Both in production.
Three domains. One senior team.
Every engagement is led by an architect or a senior engineer — no pyramid staffing, no bench.
Enterprise software
Web applications, workflow systems, portals and internal tools, API and integration layers, operational platforms.
Data, BI and analytics
Power BI and embedded analytics, Microsoft Fabric, data warehouse and lakehouse architectures, talk-to-your-data.
Cloud and security
Azure architecture, cyber security and vCISO services, training and knowledge transfer to your teams.
AI on your terms.
We believe AI over business data has to be private, verifiable and under your control. We have run all four deployment postures in production — Azure-native SaaS, hybrid with on-premise data residency, fully inside the client's own network with no data egress, and inside the client's own tenant. You pick which one your rules allow.
Local inference
Open-weight language models on your own hardware. Where the rules require it, not one token of a user's question leaves your network.
Power BI AI Assistant →Deterministic DAX
The AI does not write queries from memory — the backend builds them from a governed catalogue. Same question, same result, full audit trail.
AI Agents →MCP connectors
Connect AI assistants to the tools you already use — from accounting to internal systems.
Minimax MCP Server →Leading companies trust us.
From a government ministry to US healthcare — delivered in nine countries by the same team.
