I Make Your Marketing Data Make Sense.
I help businesses build reliable Google Ads, GTM, GA4 and server-side tracking systems so they can understand what is actually converting and make better marketing decisions.
Clicks Are Easy. Conversions Are Truth.
What happens after the click is where things get complicated. I help businesses set up accurate tracking systems so they can understand conversions, revenue and marketing performance.
Zero Conversion Duplication
Google Ads, GA4 and Meta receive the exact same, deduplicated conversions via unique event IDs so your ad spend is never burned on phantom conversions.
Smart Bidding Feeds
Automated bidding algorithms (Target CPA, Target ROAS) thrive on clean data. When you feed them verified conversions, customer acquisition costs plummet.
Ad Blocker & ITP Resilience
Server-side tracking running on your custom first-party domain prevents Safari 24h cookie wipeouts and ad blocker drops, reclaiming up to 30% lost conversions.
I'm Mahfuj. I Work Where Advertising Meets Data.
I'm a Google Ads and tracking specialist. My job is to make sure businesses can see what happens after someone clicks an ad. I set up Google Tag Manager, GA4, Google Ads conversion tracking, Meta Conversion API and server-side tracking, so the numbers in your ad accounts reflect what really happened on your site. Accurate tracking means smarter automated bidding, cleaner reports and marketing budget spent on what genuinely works.
