Summary
I'm a solution-driven product strategist and growth product manager known for my independent thinking, leadership, and proactive approach. With empathy, integrity, and active listening at the core, I bring a strategic yet creative mindset that strikes a rare balance, allowing me to see patterns and opportunities earlier than others that add value and growth.
I help founders, early-stage startups, and small teams with high-level vision and product-led growth execution, shaping the “what” and the “why” and turning complex ideas into scalable, user-centric products. At my core, I’m a product growth strategist — but I’ve worn the product manager hat often enough to understand what it takes to step into the trenches to handle the “how” and “when,” ensuring momentum isn’t lost in the gap between strategy and execution.
My professional journey has been guided by a deep commitment to tackling meaningful, real-world challenges across diverse domains. Blending product strategy and management, growth, AI, UX, and data-driven decision-making, I’ve led MVP launches, scaled features, and delivered measurable results for fintech, SaaS, and NGO initiatives across Europe and the US.
My career began in capital markets, where I spent a decade as a portfolio manager creating AI-powered tools for market analysis and portfolio management. That experience sharpened my ability to analyze markets, find gaps, build and validate hypotheses. As a founder and consultant, I’ve applied the same mindset to helping teams define vision, value proposition, and positioning, align stakeholders, and apply various growth management techniques while turning ideas into products people actually use.
What I do best:
Craft product discovery, strategy, and milestone roadmaps that align vision with execution
Drive growth by improving activation, retention, and monetization from a product-led perspective
Improve behavioral user experience heuristics that result in a better user engagement
MVP & Product-market fit advisory that helps translate human motivations into the product logic
Make blockchain scalable, usable, and useful. Apply AI and automation to unlock efficiency
I help teams build and refine products, unlock growth, and leverage blockchain, AI, and automation to streamline operations — always with a focus on solving real user problems and creating lasting impact. I seek projects with meaning and legacy, where value and purpose matter more than speed or short-term profit.
