About me
I help businesses attract customers, develop products, and make everyday work simpler. As a product manager with entrepreneurial experience, I bring together business, technology, and an understanding of what people need. My background spans SaaS, B2B and B2C projects, as well as physical products.
I start by understanding the business, its customers, and what’s getting in the way. From there, I turn ideas into practical solutions, test assumptions early, and use data to decide what to improve. I value creativity, but the goal is always a meaningful result: a better customer experience, a simpler process, or room for the business to grow.
For me, good products come from both evidence and empathy. Metrics show what’s happening. Listening to people helps explain why.
You can't know everything. You can learn anything.
