Enterprise-grade Microsoft. Modern AI.
Behind Big Bara Apps is Zoran Ružić: over 30 years of IT experience spanning SharePoint and Power Platform development to architecting agentic AI solutions. The work bridges enterprise-grade Microsoft infrastructure and modern AI innovation.
The focus today is the Microsoft Copilot stack and custom AI application development, pairing enterprise stability with custom agility.
- Microsoft Copilot stack
- Onboarding teams, architecting Copilot environments, and building intelligent agents with Copilot Studio and AI Builder.
- Agentic AI
- Architecting agents that plan, act, and hand off work across your tools, beyond scripted automation.
- Custom AI applications
- Building and deploying internal AI solutions on virtual servers with Claude Code and Antigravity.
- Hybrid automation
- Enterprise stability and custom agility combined, so automation stays reliable and stays yours.
What we build
Custom development and the Microsoft Power Platform, under one roof. Every system you run is built, connected, and maintained together.
AI consulting
Practical AI strategy for the workflows that matter. What to automate, what to build, and what to skip.
Web development
Fast, accessible, modern web apps and sites with Next.js, React, and TypeScript, built to be maintained.
SaaS development
From idea to subscription. Multi-tenant apps, billing, auth, and the admin tooling you need to grow.
Integrations
Connect the systems you already use, from CRMs and payments to accounting and internal tools, so data stops living in silos.
Power Platform
Enterprise-grade tooling on top of Microsoft 365, with governed apps and automations where your team already works.
Power Apps
Custom business apps for forms, approvals, and mobile access, shipped in days, not quarters.
Power Automate
Automate the repetitive: document flows, notifications, approvals, and hand-offs between systems.
Something custom?
If your business doesn't fit a box, tell us what it needs. We'll scope it honestly before we build it.
Selected work
Real products, built end to end: architecture, code, and deployment.
Školica
A school management platform with a React frontend, Node backend, and Dockerized deployment, built to fit how a school actually runs.

- Vite
- Node
