IT engineering from Bratislava, Slovakia
Simple, smart & secure IT.
BLUEGEM keeps the systems of small and mid-size businesses running, modernises the software they depend on, and brings AI agents onto their own infrastructure, where their data stays private.
01 Services
Everything between the server rack and the business logic.
One engineering partner for the infrastructure you run, the software you rely on and the AI you want to adopt safely.
Installations
Clean, repeatable installation of servers, databases, middleware and business applications, configured the right way from day one.
Implementations
From requirements to go-live: integrating systems, automating data flows and rolling out new tools without disrupting daily work.
Legacy code modifications
Careful changes to the systems that still run your business: Oracle PL/SQL, Java, Delphi and similar. Fixes, new features, integrations and step-by-step modernisation.
Local agentic AI
AI agents that run on your own infrastructure, on-premise or in your private environment. They automate real work with your documents and systems, and your data never leaves your control.
02 How we work
Three words we design every project around.
Simple
Clear scope, plain language and the smallest solution that does the job. No unnecessary layers, licences or lock-in, and documentation you can actually use.
Smart
Automation where it pays off, the right tool for each problem, and respect for the systems you already have. We improve what works instead of replacing it for the sake of it.
Secure
Least privilege, encryption, updates and backups by default. Your data stays on infrastructure you control, which also makes GDPR easier.
03 Products
Our own software, built and maintained in-house.
