Janaina Noga Martins

● Running an independent AI & Data PM practice embedded as a senior resource for companies and European consultancy partners. My work spans the full product journey, from data foundation and governance through to the point where the end user actually experiences value. That is the gap where most AI initiatives break down, and where I specialize.

● Developed a proprietary diagnostic covering the full AI & data product value chain, from data foundation readiness and governance gaps, through product prioritization to the consumer behavioral layer, deployed as a structured sprint offering to accelerate CPO-level decisions on where initiatives break down and why.

● Defined LLM integration strategies for client engagements, identifying where RAG, fine-tuning, or prompt engineering creates measurable user value versus adding latency and cost without adoption return.

● Established responsible AI & data practices as a product deliverable, defining model and data performance monitoring frameworks, data quality and bias detection checkpoints, and executive-facing narratives that translate AI and data limitations into realistic stakeholder expectations from day one.

● Integrated EU AI Act compliance framing as a standard capability, enabling clients to address regulatory exposure alongside strategic AI priorities.

● Mapped the end-to-end in-app student journey and applied ML models to institutional behavior data to uncover the root causes of dropout, whose findings directly reset the product's core parameters and triggered a mid-project pivot that realized the team around validated user insights.

● Appointed as interim Group Product Manager for the men's fragrance category, leading a team of 6 Product Managers and 2 Data Specialists — owning product direction, team prioritization, and stakeholder alignment across the full category portfolio.
