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.
