🎖️ Tell me where your marketing budget goes, and I'll show you which part actually works and where the next dollar should go. That is the whole job, and it is what I have done for the last 8+ years.
Most teams are measuring marketing by guessing. Last-click takes the credit, the platforms mark their own homework, and nobody can say what a channel is truly worth. I fix that with proper marketing measurement: Marketing Mix Modeling, multi-touch attribution, and incrementality testing that tells you what is causing sales, not just what is correlated with them.
I work with founders, growth leads, CMOs and marketing teams who spend real money on paid media and want to trust their numbers before they scale them.
What I build:
- Marketing Mix Models (MMM), hierarchical Bayesian, to measure each channel's true contribution and reallocate budget;
- Multi-touch attribution (Markov chains, Shapley value) across messy, non-linear customer journeys;
- Incrementality and causal inference: geo-lift, geo-holdout, difference-in-differences, synthetic control, A/B and experimentation programmes;
- Predictive models: churn, LTV, lead scoring, propensity, next best action;
- The analytics stack underneath it all: GA4, Google Tag Manager, BigQuery, Snowflake, dbt, Looker dashboards.
A few results from past work:
- 1.5M EUR unlocked through MMM-driven budget reallocation;
- 5M EUR+ in incremental revenue from a structured A/B testing and experimentation roadmap;
- 32% lift in projected lead value by moving paid acquisition to value-based bidding;
- 27% lower CPA and 15% higher conversion rate through better measurement and targeting.
How I work: I treat marketing measurement as causal. I never trust a single model, so I triangulate MMM against attribution and incrementality experiments to make sure the numbers are real. And I translate all of it into one clear recommendation a non-technical founder can act on, because a model nobody uses is worthless.
You are a strong fit if:
- You spend on paid media (Google Ads, Meta, TikTok) and cannot prove what is working;
- You need MMM, attribution, or incrementality testing done properly;
- You have data but no clear path from data to decision;
- You want senior judgement, not a junior running a template.
Not a fit if:
- You want last-click attribution to keep telling you what you want to hear;
- You are looking for the cheapest possible setup over a correct one
My stack: Python (pandas, scikit-learn, PyMC), R, SQL, BigQuery, Snowflake, dbt, Vertex AI, Looker, GA4, Google Tag Manager, Google Ads, Meta Ads.
I am a PhD candidate in Data Science at NOVA-IMS researching causal inference, so you get academic rigour combined with in-house growth-team pragmatism.
Expertise: Marketing Mix Modeling, MMM, Media Mix Modeling, Marketing Measurement, Multi-Touch Attribution, Attribution Modeling, Incrementality Testing, Geo-Lift, Causal Inference, Bayesian Statistics, Marketing Analytics, Predictive Modeling, Churn Prediction, Customer Lifetime Value, LTV, Propensity Modeling, A/B Testing, Experimentation, GA4, Google Tag Manager, Conversion Tracking, BigQuery, Python, Data Science.

I create fully illustrated, KDP-ready children’s books — from character design to final print-ready files.
I help authors turn manuscripts or ideas into fully illustrated, formatted, and print-ready children’s books for Amazon KDP.
Most clients come to me when:
• illustrations don’t match across pages
• books fail KDP upload due to formatting issues
• they need someone to handle both illustration and publishing
I solve this by combining illustration skills with real KDP publishing experience.
What I can do for your book:
✔ Full children’s book illustration (characters, scenes, storytelling)
✔ Consistent character design across all pages
✔ Cover + interior design aligned with KDP requirements
✔ KDP formatting (margins, bleed, trim size, layout)
✔ Fixing KDP upload errors (interior & cover)
✔ Delivering print-ready files (PDF, PNG, 300 DPI)
I also run my own coloring book projects, so I understand not only design — but what actually works and sells on KDP.
Experience:
• 70+ listings on Etsy
• 40+ real sales with 5★ reviews
• 27 books published on Amazon KDP
I focus on fast delivery, clear communication, and making the process easy for you.
If needed, I can create a quick sample to match your style before we start.
Let’s make your book ready for publishing 👍
