Cost-minimizing cloud design, hybrid on-premise and cloud infrastructure, migrations to OCI, AWS or Azure.
Learn more →Legacy code & reverse engineering
Delphi, Oracle PL/SQL and Java: careful changes, reverse engineering and step-by-step migration to modern languages and frameworks.
Learn more →AI automation
Document processing, email triage, reports and data checks automated with private AI, with human approval where it matters.
Learn more →Local agentic AI
On-premise AI agents and local LLMs that run on your own infrastructure or in your private environment. They automate real work with your documents and systems, and your data never leaves your control, which keeps GDPR simple.
Private AI agents & local LLMs →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

Engineer-led and hands-on.
BLUEGEM is a small engineering company based in Bratislava, Slovakia, in the European Union. We work remotely with small and mid-size businesses worldwide, in English, from the Central European time zone.
You talk directly to the engineer who does the work: no account managers, no ticket ping-pong. We are comfortable both in modern Linux environments and in long-running business systems that many others prefer not to touch.

05 FAQ
Questions about working with us remotely
Do you work with clients outside Slovakia?
Yes. All our services are delivered remotely, so location doesn't matter. We work in English, from the EU, in the Central European time zone, with clients across Europe and beyond.
Which services can you deliver fully remotely?
All of them: Linux server administration, installations and implementations, legacy code maintenance and modernization for Delphi, Oracle PL/SQL and Java, and private, on-premise AI agents deployed on your own hardware.
How do you access our systems securely?
Through access you create and control, such as a personal SSH key, your VPN or remote desktop, with only the privileges the task needs. You can revoke access at any time, and every change is documented.
How do you handle data protection and GDPR?
BLUEGEM is an EU company, so GDPR applies to everything we do. We keep your data on your infrastructure wherever possible and can sign a data processing agreement where personal data is involved.
How do we start?
Send a short email describing your systems and what you need. You'll get a reply from the engineer who would do the work, usually with a few questions and a proposal for a first, small step.
