Cover image for I used to break my
I used to break my toys. Not because I wanted to destroy them. I wanted to know what was inside. How did it work? Why did it move? That curiosity never really left me. Years later, I started learning digital marketing with a borrowed laptop. I remember getting my Google Digital Garage certificate. I was so happy that day. I even thought: “Maybe one day Google will hire me.” Then I asked my father for a computer. For almost six months. Eventually, he agreed. But there was a condition: If I got the computer, I had to take responsibility for everything after that. Internet. Tools. Everything. So I started freelancing. I opened Fiverr with almost no idea how freelancing actually worked. I didn’t understand positioning. I didn’t know how to find clients. I depended almost completely on one marketplace. Then my second order got cancelled. My account went down. Money was already tight. At one point, I struggled to pay my internet bill. And the internet wasn’t just entertainment for me. It was the thing I was trying to build my future with. People around me also didn’t really understand how someone could build a career online. The traditional path was familiar: Study → degree → stable job. So when I said I wanted to build my career through the internet, not everyone believed me. I don’t blame them. They were judging the future based on what they had seen. So I decided to prove it through results. I tried. I failed. I tried different businesses. I lost clients. I made mistakes. I started again. Eventually, I realized Fiverr wasn’t the entire internet. I explored other opportunities, joined Upwork, started working with clients from different countries, and eventually earned Top Rated status. Today, I work in web analytics and conversion tracking. GA4. GTM. Google Ads tracking. Meta Pixel + CAPI. Server-side tracking. Data layers. Consent Mode. And there’s something funny about the journey. As a kid, I took things apart to understand how they worked. Today, I do the same thing with websites and marketing systems. I take them apart. I look at the data. I find what’s broken. Then I build it properly. I’m still learning. Still experimenting. Still failing sometimes. But I’m still curious. I was once a kid who wanted to know what was inside a toy. I’m still that kid. I’m just opening different things now.

Cover image for I’ve been working in digital
I’ve been working in digital marketing and analytics for years. But I’m still learning how to explain what I actually do in a simple way. So, let me introduce myself. I’m Jobair Mahmud, a Web Analytics & Conversion Tracking Specialist from Bangladesh. I started with digital marketing and paid advertising. Then I became more interested in something most marketers don't spend much time thinking about: What actually happens after someone clicks the ad? That question took me deeper into: → Google Analytics 4 → Google Tag Manager → Google Ads Conversion Tracking → Meta Pixel & Conversions API → Server-Side Tracking → Enhanced Conversions → Consent Mode → Data Layer & Ecommerce Tracking → Attribution & Marketing Analytics Over time, I realized something. Running ads and measuring ads are two different problems. A campaign can have great creatives. The targeting can be good. The budget can be right. But if the conversion data is incomplete, duplicated or incorrectly attributed, the decisions made from that data can still be wrong. That’s why I enjoy working on the technical side of marketing. I like connecting the pieces: Ad → Website → Data Layer → Tracking → Conversion → Attribution → Business Decision Today, I work with agencies, eCommerce brands, SaaS companies and businesses running paid advertising to make that measurement more reliable. I’m not interested in simply installing another tag. I want to understand what the business is trying to measure, where the data is coming from, where it is getting lost, and whether the final numbers can actually be trusted. I’ll be sharing more about what I learn from real tracking problems, Google Ads, Meta Ads, GA4, GTM, server-side tracking and marketing analytics here on LinkedIn. If you're working in performance marketing, analytics, eCommerce or paid advertising, I’d love to connect. And if you’re building an agency or business where better tracking and better data matter, let’s talk. What part of marketing measurement do you think marketers overlook the most?

100+ Buisness and Agencies can’t be wrong. When I started offering tracking setups, I wanted one thing to make ads data-driven again. Now, over 100 agencies trust my service to fix their Meta CAPI, GA4, and Shopify tracking setups. Because when tracking works → ads perform → clients stay happy. If you’re a web developer or marketing agency on Contra, let’s collab! I offer white-label tracking setups that make your projects run like a dream.
