Previously, purchasing decisions were made by the CTO, CIO, or Procurement department. Today, a single developer can spend more money in an afternoon than the entire accounting department audits in a month — without even realizing it.
Every API request, every memory access, every log line is a microtransaction. Cloud providers are not just infrastructure providers, but billing systems. Those who don't understand pricing risk enormous sums of money.
In my role as a senior backend developer, I now automatically consider the financial impact of every technical decision. This isn't about being penny-pinching, but about professionalism: efficient systems are generally also more stable, faster, and require less maintenance.
Inexperienced developers tend to overlook details:
These details are expensive — and are immediately monetized in the cloud.
Companies need developers who understand the technical and economic consequences of their code. This is precisely the experience I offer: professional backend development that considers performance, maintainability, and cost together.
