Top Rated on Upwork · 100% job success · All 5-star reviews. I've built bulk import systems that cut 100+ hours to 2, published open-source plugins on WordPress.org, and migrated 50-page multilingual sites with zero downtime.
Every review is 5 stars. Every project is delivered to spec. That's not luck — it's process.
Star ratings are not enough to describe the work Saddam did for us. He customized an extremely complicated WordPress plugin by creating his own data import system. We went from 100+ hours of manual work to just 2 hours. Exceptional work, exceptional developer.
Excellent freelancer. I have been working with him for years — he is reliable, skilled, and a genuinely excellent person to work with. Highly recommend.

Coming soonA high-traffic WooCommerce store was scoring 42 on PageSpeed. Here is exactly what I did: Cloudflare CDN setup, LiteSpeed cache configuration, WebP image conversion, critical CSS extraction, and query-level database tuning. No plugins guessing — all intentional.
Coming soonI kept seeing the same security, performance, and compliance issues across client WordPress sites. So I built SiteProof AI — a plugin that runs 4-layer automated scans and generates fix suggestions using Claude 3.5 Sonnet API. This is how I built it.
