10+ years building reliable production systems

My name is Constantine Vysotskyi. I'm a backend and systems engineer based in Chicago, IL.

I've spent 10+ years designing and operating infrastructure for healthcare IT: systems that process medical imaging data in real time at 2+ Gbps sustained throughput. When something can't go down, I'm the person who makes sure it doesn't.

Now I bring that same approach to small business: reliable infrastructure, clear ownership, and one person who actually answers when something goes wrong.

How I work

How I work

01
One person, full responsibility
You deal with one contact for everything — not a support queue. I know your setup, your history, and your business.
02
Proactive, not reactive
I'm watching your infrastructure before something breaks. Monitoring, updates, backups — this happens without you asking.
03
Your business grows, your IT grows
I'm not here to sell you a bigger plan. I'm here to make sure your technology fits where you are now — and scales when you're ready.
