I cut your Cloud & Bare Metal OPEX by 20–30%.
No code refactoring. No BS.
Stop bleeding margin on over-provisioned infrastructure. I analyze your workloads, map them to cost-optimized hardware (like Hetzner), and you keep the savings. I only get paid if I actually find them.

The Mechanics of OPEX Optimization
No marketing dashboards. Just math. Here is a sample workload mapping.
The "No-Headache" Optimization
- ✓ I don't touch your code.
Your developers keep doing their jobs. My optimization happens strictly at the infrastructure layer. - ✓ I don't need your data.
This is a 100% offline audit. Give me your CPU/RAM/IOPS. Keep your secrets and databases to yourself. - ✓ Pure success-fee model.
If I find €50k in yearly savings, I take a defined cut. You take the rest. Forever. If your setup is perfect, you pay nothing.
Who I help
- ✓ High-Volume SaaS
You are scaling fast, but your Hetzner/AWS invoice is eating directly into your margins. - ✓ Managed Service Providers (MSPs)
Every euro saved on the underlying hardware is pure, bottom-line profit for your agency. - ✓ Data-Heavy Operations
You run ClickHouse, ElasticSearch, or large clusters and overpay for raw IOPS and RAM.
Behind drknowhow.co
Dominik Zalewski – Former Lead Engineer and CTO. I've spent years watching companies burn money on infrastructure because they use the wrong instances for the right jobs.
I don't sell "digital strategies". I sell a highly specific, mathematical understanding of bare-metal pricing tiers and hardware capabilities. I find the inefficiencies, give you the exact blueprint to fix them, and guarantee the financial result.
