From Maintenance Mechanic to Software Revolutionary

I am a maintenance mechanic by trade. At 56 years old, I know the shop floor, machinery, and efficient processes inside out.

Recently, when video games got too boring in the evenings, I grabbed PowerShell and just started coding. After all, as a mechanic, you don't install a half-repaired gearbox—it simply has to work.

My personal endurance test: I wanted to buy a new gaming laptop on eBay. Since the market is full of unstructured text chaos, defects, and fake offers, I built my own search and calculation tool. The result?

An MSI Delta 15 (market value approx. €900) scored for exactly €463, because my algorithm mathematically calculated bidding behavior and risks perfectly.

That's when it hit me: What saves me money privately solves a multi-million dollar problem in B2B re-commerce and IT refurbishment [Fehr Algorithmus Watch].

Large procurement teams are drowning in their warehouses due to manual research for market prices and spare part costs. A single overlooked error quickly costs companies thousands of dollars in margin.
Today's tech world tries to solve everything with massive, sluggish AI models that cause unpredictable server costs.
I did the exact opposite: Radical lightweight construction.
My system, Fehr Algorithmus Watch, is an independent, extremely lean logic infrastructure. Just 400 KB in size, native Linux core, local search caching [Fehr Algorithmus Watch]. No server costs, no hallucinations.

List in, loaded, results are there.
The real market price median.
