Growth is more than a single metric.
I'm Ali Demirbaş. I work on digital product growth, user acquisition and performance.

About
A career across growth, CRM and measurement.
I started in digital marketing, then moved through user acquisition, CRM analytics, lifecycle and mobile product growth. Today I see them as different parts of the same customer journey, not separate disciplines.

What I do
I use data, experiments and product behavior to find the next growth problem.
These are the areas I work in and the tools I built around them.
Measurement setup
Event design in GA4 and GTM, Adjust setup, and finding where the gap comes from when two platforms report different numbers for the same week. What's left is an event structure the team can query, with every definition written down.
Built for this: Dashboard BuilderLifecycle and CRM programs
I design the journeys a user goes through from first step to win-back, and write down why each message actually gets sent.
Built for this: Journey LibraryGoogle Ads Change History
I track changes made across Google Ads accounts alongside date, campaign and performance data, so a shift in results doesn't turn into a guessing game.
Built for this: Google Ads Change HistoryTest, learn, improve
I collected 211 A/B test scenarios covering every stage from acquisition to retention. Each one states what is being tested and how it should be measured.
Built for this: A/B Test Playbook
