Reliable IT support
in Bucharest.
Computers, Wi-Fi, networks, cameras, and technical problems — solved quickly and affordably. Local IT technician with 10+ years of experience helping people and small businesses.
I don't just fix problems — I design the infrastructure that prevents them.
// common problems
Sound familiar?
These are the kinds of problems I help people solve every day. If something on this list matches your situation — I can help.
Slow or unreliable Wi-Fi that drops at the worst times
Computers that crash, freeze, or run painfully slowly
Printers that stop working and refuse to cooperate
Internet or network problems you can't figure out
Setting up cameras and security systems
Data backup and protection from hardware failure
// services
What I can help you with.
Practical IT solutions — explained in plain language, done properly, and built to last. I focus on finding the most cost-effective approach to real problems, so you get reliable results without overspending.
Computer Support
Computers that work the way they should — fast, stable, and frustration-free. Windows and Linux.
Reliable Networks & Wi-Fi
Networks and Wi-Fi that actually work — no dead zones, no drops, no mystery disconnections.
Business IT Setup
Everything your shop or office needs to run smoothly — POS, printers, computers, and network, all set up and working together.
Security & Monitoring
Surveillance and security systems that give you visibility and peace of mind — at home or at work.
Data Protection
Protecting your data so a hardware failure never destroys your business. Automated, local backups you can count on.
Self-Hosted Infrastructure
Own your infrastructure instead of renting it. Systems designed to be reliable, documented, and under your control.
Private AI Assistants
Your own AI assistant for your business — secure, private, and running on your own hardware. No cloud subscriptions, no data leaving your office.
Infrastructure Consulting
For teams and technical businesses that need systems designed properly — identity, virtualization, networking, and automation.
Workflow Automation
Repetitive tasks slowing your business down? I build automations that save you time, reduce errors, and let you focus on what actually matters.

// infrastructure lab
Built and operated in a real lab.
Most IT providers describe systems they've read about. My work is built on a dedicated lab environment where real infrastructure is designed, tested, and maintained continuously.
Every service I offer has been deployed and operated in this environment first — failures included.
The lab runs under the internal domain eendi.unix and mirrors the architecture of a small enterprise environment: segmented networks, centralized identity, internal certificate infrastructure, and a full virtualization layer.
If a design works here, it works in production.
Virtualization
- Proxmox VE hypervisor cluster
- LXC containers lightweight workloads
- KVM / QEMU full VM isolation
- ZFS storage with snapshots
Identity Infrastructure
- FreeIPA directory + DNS + CA
- SSSD + Kerberos centralized authn
- Zitadel OIDC / OAuth2 IdP
- Internal PKI TLS for all services
Network Architecture
- OPNsense firewall & routing
- VLANs segmented networks
- WireGuard remote access VPN
- Internal DNS split-horizon zones
Operations
- Arch Linux daily driver + servers
- Ansible configuration management
- Git self-hosted repositories
- Monitoring stack Grafana / Prometheus
// infrastructure consulting
I design systems, not just fix computers.
I design and build reliable infrastructure for small teams, developers, and technical businesses that want more control over their systems.
This includes identity systems, virtualization platforms, self-hosted services, automation, and secure network architecture.
Everything is designed to be understandable, documented, and maintainable long-term.
Example projects:
- Self-hosted infrastructure with Proxmox virtualization
- Identity and access management with FreeIPA / Zitadel
- Secure internal networks and service segmentation
- Backup and disaster recovery strategies
- Private AI systems running on local hardware
// my approach
Systems thinking, not quick fixes.
Technology problems are rarely isolated. Slow networks, unreliable systems, and security issues usually come from poor infrastructure design rather than individual devices.
My approach focuses on understanding the entire system — network, services, authentication, backups and workflows — so that solutions remain stable and maintainable long-term.
I test most solutions first in my personal lab environment before recommending them for production use. Technology solutions should not be based on theory — by running and maintaining my own infrastructure, I gain real operational experience with the same systems that businesses rely on every day.
// portfolio
Real projects, real infrastructure.
A selection of systems designed and deployed — in the lab and for clients.
Identity Infrastructure Deployment
Design and deployment of centralized authentication using FreeIPA with integrated DNS, Kerberos, and an internal certificate authority for encrypted service communication.
Proxmox Virtualization Cluster
Multi-node Proxmox cluster with ZFS storage, LXC containers for services, and KVM virtual machines for isolated workloads. High-availability configured.
Federated SSO with Zitadel + FreeIPA
Integration of Zitadel as an OIDC/OAuth2 identity provider backed by FreeIPA, enabling single sign-on across self-hosted services without cloud dependency.
Segmented Network with OPNsense
VLAN-based network segmentation with OPNsense firewall, per-zone traffic policies, split-horizon DNS, and WireGuard VPN for remote access.

Infrastructure Consultant
My name is Endre — but everyone calls me Endi. I've been working with technology since 2015, and I enjoy building systems that are reliable, understandable, and under the control of the people who use them.
Whether it's a home Wi-Fi issue or designing infrastructure for a technical business — I approach every problem with the same care and attention to detail.
Through EndreEndi Services, my goal is to provide practical and reliable IT help — from everyday support to infrastructure consulting. Good technology shouldn't require a corporate budget.
Outside of work, I run a dedicated lab environment where I design, break, and rebuild systems continuously. If you want to see what's inside it, the Lab section covers the full stack.
Technologies I work with
Systems
Linux & Windows
Networking
Routers, firewalls, VLANs
Virtualization
Proxmox, containers
Security
Identity systems, PKI
Automation
Ansible, scripting
Backup
Disaster recovery
