In a world where everyone uses AI to generate spammy content, at Tekin Plus, we decided to use it for "Digital Heart Surgery." We recruited a team of advanced AI agents—including Trae, Amazon Kiro, and Claude Opus 4.5—to refactor our legacy code. The mission? To escape the critical "Red Zone" (failing scores) and achieve a stable, high-performance "Green Zone." In this honest case study, we don't just brag about high numbers; we break down the technical reality of Google PageSpeed fluctuations, the myth of the "Permanent 100," and how AI became our Lead Engineer.
1. Introduction: Confessions of a Webmaster Hello friends, Majid here. Today, I want to pull back the curtain and share a truth that is somewhat painful to admit, yet incredibly educational. Until very
recently, if you had run "Tekin Game" through Google’s testing tools (PageSpeed Insights), you would have been met with a bloody scene. We were seeing scores in the 40s and 50s. We saw Red and Orange warnings
everywhere. Technical errors, heavy code, and layout shifts were acting like a handbrake, stopping our site from reaching its full potential. We had great content, but "under the hood," the engine was
struggling. What was the solution? Should we hire a massive team of senior developers and spend thousands of dollars? Or should we trust the technology of the future? I chose the second path. I decided
to tear down our code and rebuild it using the most advanced AI tools available—tools that many in the general public don't even know exist yet. 2. The Reality Check: The Myth of the "Permanent 100" Before
we dive into the tools and the code, I need to clarify a crucial technical point. In the screenshots we share, you will see scores of 100. But does this mean the site speed is always 100, every single
second of the day? The short answer is: No. And anyone who promises you a "Permanent 100" is lying to you. 2.1. Why Do Scores Fluctuate? Google PageSpeed Insights is a simulation. Every time you click
"Analyze," Google spins up a virtual machine in a different data center (it could be in the US, Europe, or Asia). It then throttles the network to simulate a slow 4G connection. Because of network latency,
