About

Specialized in user behavior analysis and behavioral product strategy. For 5+ years, I shipped products at Day.io (SaaS B2B time tracking & payroll), reducing support friction by 30%, accelerating workflows by 20%, and leading cross-functional teams across 3 countries.


Then I stepped back to formally study Psychology and Neuropsychology, because I realized the best product decisions come from understanding how people actually think and decide. I spent 3 years conducting user research, analyzing decision-making patterns, and studying cognitive biases.


Now I'm bringing both together.


What I do:

- Product discovery grounded in user behavior & psychology

- UX design using behavioral economics principles

- AI-assisted product strategy (LLMs, prototyping, automation)

- Cross-functional leadership in distributed teams


I'm looking for: Associate/Mid-level Product Manager roles in SaaS, AI-native companies, or high-growth startups where behavioral insights drive product decisions.


Let's talk if you're building something that puts user psychology at the center.
