Hi there👋

🔹 I help organizations turn data into scale products, bridging my background as a Data Scientist and AI Engineer with my current role as Chief Product Officer. I focus on data Product Strategy, transforming raw data into trusted, usable, and monetizable products.

🔹 With 7+ years leading enterprise data science teams (Allianz, startups) and now building SaaS at ARIF, I’ve seen how models, dashboards, and pipelines fail without a product mindset. That’s why I work on frameworks that move teams from data as an asset → data as a product.

Some highlights from my journey:
✅ Propensity models that drove 150% of Allianz’s annual revenue targets
✅ Fraud detection systems reducing losses by 7-figure margins
✅ LLM-powered chatbots with RAG cutting customer support costs by 30%
✅ SaaS data platform (ARIF) turning advanced analytics into a productized experience

🔹 I also share what I learn. I’ve written 500+ articles (KDnuggets, Towards Data Science, MachineLearningMastery, Non-Brand Data) for 2M+ monthly readers, translating complex AI/ML + data strategy concepts into actionable playbooks.

🔹 Today, I collaborate with professionals and organizations on:
👉 Consulting: Data product strategy, machine learning pipelines, and LLM product design
👉 Content & Speaking: Articles, workshops, and keynotes on Data Science and AI

📌 If you want to bridge the gap between data teams and business outcomes. Let’s talk.
