“Excellent experience with Shahzada. He is very knowledgeable in all areas of tracking and analytics; I would highly recommend him.”
Matt CooperShake That Weight
Shake That Weight sells meal-replacement shakes, meals and diet plans in the UK. Matt Cooper first hired Shahzada, now Crisper's founder, in 2023 to set up Google Tag Manager. In June 2025 he came back: after a consent change and a new TikTok pixel, the store's tracked conversions had dropped.
A Tag Manager setup, then two years of changes
In April 2023 Matt hired Shahzada for a Google Tag Manager setup on the web and the server, with custom data layer code. The UK store runs on WordPress and WooCommerce.
Over the next two years the team kept adding to it. A TikTok pixel went on the site, and consent mode came in through a cookie banner from CookieInformation. Separate freelancers ran the Google, Meta, TikTok and Snapchat ads.
Conversions dropped, so he called back
In June 2025 Matt asked Shahzada to review the setup. Since the consent change, tracked conversions had dropped, and GA4 conversion tracking was not working.
Shahzada scanned the UK store and wrote an audit. The TikTok, Microsoft Ads and Awin tags ran only in the browser, and Safari was cutting cookie lifetimes short. He also asked for the store's own WooCommerce order data to check the analytics against.
What changed in July and August 2025
In July the team hired him to fix the UK store and its sister store, EatProtein. Tracking on the UK store was moved to load from a subdomain of its own domain, which makes it more resistant to ad blockers. Enhanced conversions were turned on, and Google Ads kept optimizing for the ProfitMetrics conversion the team already used.
In August the CookieInformation banner came off the site. Shahzada rebuilt its default and update consent signals inside Google Tag Manager to behave the same way.
That July, Matt also passed Shahzada's name to another business.
Facts come from the Upwork project threads, project emails and Matt Cooper's public 2023 review. A tracking project by Shahzada Ali Hassan, Crisper's founder.

“Hassan resolved a complex GTM issue in just one hour, after I had spent nearly a month working with Google Support with no success. His expertise is exceptional, and I highly recommend his services!”

Payment method required at checkout. One trial per domain. The 30 minutes start once tracking is installed and events fire; it is visibility in Events Manager, not same-day ROAS.
