Mehma K.

Website Speed Optimization and Core Web Vitals specialist. I make slow WordPress and Shopify sites fast, and build headless Next.js front ends when the platform itself is the ceiling. I help businesses fix slow, underperforming WordPress and Shopify websites and turn speed into measurable revenue. Most sites I take on are losing sales to slow load times, failed Core Web Vitals, and years of plugin and theme bloat. I strip that back and rebuild it fast, clean, and built to convert. ➜ Recent results: » Shopify store: custom development + speed optimization → $49K additional monthly revenue (42% increase) » Corporate WordPress site: migrated to headless Next.js → 67% faster load, 38% more leads » SaaS platform: performance optimization → now handles 25K+ concurrent users smoothly » Top clients have seen 35–50% revenue increases within 90 days of launch or optimization Top Rated on Upwork. 100% Job Success. 5.0 across 13 reviews, 28 jobs, 563 hours logged.
