In cloud environments, costs are no longer solely determined by architecture, but often by a single line of code. Many companies fundamentally underestimate this dynamic. While the finance department scrutinizes every office supply, five- or six-figure sums often flow unnoticed into the cloud—triggered by decisions developers sometimes make casually.
As a senior backend developer, I've repeatedly seen this pattern in real-world projects: log output that was never removed, prototypes that continue to exist as production code, and API loops that seem harmless under low load but ignite a cost explosion with millions of requests.
A Lambda function may cost 800€ per month—but the associated CloudWatch logs generate 30000€. The code functions perfectly from a technical standpoint, but a debug statement was never removed. The result: over a million dollars in annual costs for unnecessary log data.
Experience makes all the difference here. A beginner initially writes working code—but cloud experience means thinking ahead: What happens with 10x, 100x, or 1000x the load? What side effects does my decision create in a cloud provider's pricing model?
Companies don't save money by cutting corners in the wrong places. A poorly built cloud service isn't just expensive; it jeopardizes the profit margin of the entire product.
I help companies do exactly that: develop robust, scalable, and cost-efficient systems that remain profitable even under heavy load.
