SELECTED WORK

Real results from 5 years of performance marketing.

Cutting Paid Acquisition Cost by 93%

OUTCOME
CPI dropped from ₺100 to ₺7 within two weeks (a 93% reduction).

Analytics Looker Studio Automation

Moving Manual Reporting to Automation Across 10 Brands

PROBLEM
Performance reports were built manually for each brand — costly in time and inconsistent in how the data was presented.
APPROACH
Built automated Looker Studio dashboards for 10 global brands, unifying data sources (GA4, ad platforms) into a single panel.
OUTCOME
Two separate teams adopted the reporting and kept using it without needing me in the loop.

About Me

ABOUT

For me, a campaign "working" isn't enough on its own. I want to understand why it works, which segment is actually converting, and whether every dollar of spend is being measured correctly.

I hold an M.Sc. in Business Engineering from Yıldız Technical University. Over 5 years at a digital agency I delivered performance marketing and analytics products for 10 global brands: cut ad cost by 93%, contributed 250 new monthly customers through behavioural segmentation and automation flows, and built automated reporting systems for 10 global brands. I now offer that same data-driven approach as a freelancer in SEO, ad management and social media management.

I currently work as an AI Product Manager on AI and LLM-based products — which gives me a different depth in how I use data and automation in marketing too.

Career

EXPERIENCE

AI Product Manager
February 2026 — Present
Delivering AI and analytics products end to end for 5 enterprise clients in a 5-person squad: problem definition, scoping, delivery and measurement. Ran product discovery for a national retail chain, defined 7 AI use-cases — all entered development — and put a working demo in the client's hands in 2 weeks. For a national logistics operator: demo in 3 days, then an image-analysis product covering 500 in-vehicle cameras continuously, replacing an entirely manual process. Led the model selection decision on a publicly funded marketing LLM: evaluated 4 Qwen 3.5 variants on a 500-question benchmark scored with LLM-as-judge; the 27B model did not win. Identified 12 metric inconsistencies in the evaluation pipeline and rebuilt it. Designed a 200,000+ record synthetic data pipeline; training on H200 GPUs.
Senior Product Analytics & Marketing Specialist
Digital agency
February 2021 — February 2026
Analytics and performance products for 10 global brands; progressed from specialist to senior over 5 years and took management responsibility in a 5-person team. Cut cost per install from TRY 100 to TRY 7 (93% in 2 weeks): ran 4 audience segments against 5 creative x 5 copy variants in parallel, tracked at ad-set level, shifted budget to the winner — attribution verified via Firebase and AppsFlyer. Mapped the customer journey end to end, built 6 behavioural segments with automated Mailchimp lifecycle journeys; contributed to 250 new customers/month on a single B2B brand. Built 10 automated Looker Studio reports used by 2 teams without going through me.
