IT freelance & future company. Currently building — open for work, open for deals, open for everything. Let's build something together.
I'm Luka Cosic, an IT Systems Specialist based in Belgrade. By day I manage multi-site infrastructure at Dr.Max — Cisco networking, Active Directory, Azure, VMware, MDM, and everything that keeps a large operation running.
Alatreon is the next chapter. I'm registering as Paušal and starting to take on independent work — IT consulting, networking, web development, helpdesk support, and more. Small jobs, big jobs, one-time fixes, long-term partnerships — I'm open to it all.
The goal is simple: build a portfolio, meet people, deliver great work, and grow this into something serious. If you need an IT person who actually knows what they're doing — you found one.
Full LAN & Wi-Fi setup, Cisco & MikroTik configuration, rack builds, cable management, access points, switches, routers. From scratch or troubleshooting existing setups.
Remote and on-site IT support, Windows/Linux troubleshooting, hardware repair, PC builds, laptop maintenance, peripherals. Fast, reliable, no nonsense.
Active Directory, Azure AD, user & group management, virtualization (VMware vSphere, VirtualBox), MDM with SOTI MobiControl, multi-site infrastructure.
Front-end development, landing pages, personal & company websites, interactive CVs, small business web presence. Clean, fast, modern. No bloat, no templates.
Video surveillance installation and configuration, anti-fire alarm systems, cable routing and commissioning. Proper setup, properly documented.
Starting a small business and don't know what IT you need? Need someone to plan, buy, and set up your office network from zero? That's exactly the kind of project I want.
This is the beginning. Alatreon starts as a Paušal — one person, doing great work. But the plan is bigger than that.
Take on projects, deliver quality, document everything. Every solved problem is proof of capability. Starting with whatever comes — no job too small.
Meet business owners, developers, designers, IT people. The right connections matter more than certificates. Open to partnerships, referrals, collaborations.
Start solo, grow smart. The goal is a small but serious IT company handling networking, infrastructure, and development for businesses in Serbia and beyond.
No overselling, no fake expertise. If I know it — I'll do it right. If I don't — I'll tell you. That's the kind of IT guy businesses want long-term.
I'm actively looking for freelance work — one-time projects, ongoing support contracts, partnerships, anything in between. If you have something that needs an IT person, let's talk.
Especially interested in working with small businesses that need to set up or fix their IT, companies looking for a reliable network/support guy, and anyone building something cool who needs tech help.
