Who built this, how to reach me, and what it collects

I’m Razan Aboushi, a full stack engineer who builds scalable, high-performance web applications in JavaScript, TypeScript, React, Next.js and Node.js. I designed, built and maintain SEOLens Evidence.

Most of my work sits exactly where this tool does: Core Web Vitals, page-load performance, and the measurable difference they make to how a page is experienced and ranked. That is not a coincidence. An analyzer that refuses to estimate a number it could not measure was built by someone used to being held to real ones.

I studied Management Information Systems at the University of Jordan, finishing with a GPA of 3.94 out of 4, and have spent the years since moving from theory into production — shipping features, hunting down performance bottlenecks, and working across teams on systems real people depend on. I like turning complicated problems into simple, efficient solutions, and I care about code someone else can still read a year later. I also write about engineering, debugging, and where AI genuinely helps in this work.

I’m open to working on products where engineering quality is taken seriously. If that is yours, LinkedIn or razanalqaddoumi@gmail.com both reach me.

Every criterion it applies is documented in full on the methodology page — the weights, the thresholds, which values are heuristics rather than requirements, and an explicit list of what cannot be determined. If a finding looks wrong, that page is where to check it against, and the fastest way to get it corrected is to tell me.
