Redis rate limiting for APIs: sliding window ZADD with Lua atomicity, in-memory fallback, multi-tier limits by IP and API key, and developer-friendly response
We publish 20-30 news articles per day and indexing latency was killing us — by the time Google crawled a story, the news cycle had moved on. Iurii's audit covered IndexNow setup, a sitemap that was hitting size limits and dropping URLs silently, and canonical tags that were inconsistent between AMP and non-AMP versions. The IndexNow integration alone moved median time-to-index for Bing from days to under an hour. Report was direct, no fluff, exactly what we needed.

Our internal dashboard was painfully slow and we had no idea where the problem was. Iurii looked at it and pointed to two specific things in the database that were causing it. We fixed them and the page went from 9 seconds to less than one. I didn't expect it to be that fast to diagnose.

Our app had slowed to a crawl and the previous developer had left no documentation. Customers were starting to churn over load times. Iurii profiled it instead of guessing, found a handful of unindexed queries and a runaway N+1 that were doing most of the damage, and had page loads back under a second within the first week. He fixed the actual causes rather than throwing more server at it, and wrote up what he changed so we wouldn't repeat the same mistakes.

Our Next.js site was failing Core Web Vitals on mobile and we couldn't figure out why — Lighthouse scores looked fine locally. Iurii's audit pinned it down: an unoptimized hero image on the homepage, third-party scripts blocking the main thread, and a font-loading strategy that was causing layout shift on every page. The fixes were specific enough that one of our developers shipped them over a weekend. CLS dropped from 0.24 to 0.03 and we passed the assessment two crawl cycles later.
