How I work
From slow & unseento fast & found.
№ 01
Audit & Diagnose
I profile the site and find the real bottlenecks — render-blocking assets, bloated media, weak Core Web Vitals — then map the highest-impact wins.
№ 02
Build & Optimise
A custom build — a WordPress site, a Next.js or React web app — with clean code, next-gen images, caching and a CDN, tuned until every vital turns green.
№ 03
Measure & Hand Off
Documented before/after PageSpeed scores, so the result is provable — and the site stays fast long after launch.
What clients say
Clear communication. Fast execution. Strong results.

Director of Operations and Analytics at BuyandBill.com and Alchemy Healthcare Solutions
Hammed is the best developer I’ve worked with on Upwork so far. Highly responsive, willing to simplify things for non-technical customers, and he even worked over the weekend to get our performance issues resolved. He will be our go-to for these types of projects moving forward.
