Hi, my name is Piotr Hajkowski. I spent over a decade as a BI & Data Warehousing consultant, working mainly with Oracle software, data integration, and performance tuning.

Over the last 8 years, my focus has shifted to DevOps engineering, cloud cost optimisation (FinOps), compliance, and cloud security. Through my company, Agapios, I help engineering teams build and operate secure, compliant, and run cost efficient cloud infrastructure.

Out of that hands-on FinOps work, we built CloudTally – a European cloud cost management and FinOps platform for Hetzner Cloud cost tracking. When you combine a decade of data warehousing with 8 years of DevOps and cloud billing audits, CloudTally is the product that naturally comes out of it.

90% of a consultant’s work time is spent on projects. This is where my experience comes from. It happens to me quite often when I’m thinking of some technical problem that many ideas pop up in my head. They are not always related to the problem I’m thinking about. Sometimes they are useful, sometimes not so much. “Why not to share it?” I asked myself one day. This question brought me to the blog.

This blog is where I originally stored and shared my observations, ideas, and thoughts on data warehousing and Oracle technology. I hope you will still find some useful stuff here. For my recent articles on European cloud infrastructure, Hetzner billing, and FinOps, visit my other blogs: CloudTally product blog and Agapios company blog.
