I am Lead Product Designer focused on delivering value to both the user and the business, while working within the available budget and technology constraints. It's as simple as that.
From research to handoff — I design complete product experiences that are user-centered, scalable, and development-ready. Whether you're launching a startup or rethinking an enterprise platform, I'll guide you through every step of the design process.
Need to validate your idea fast? I help founders and product teams turn early-stage concepts into tangible MVPs and proof-of-concepts (nocode + vibe coding) that investors and users will understand — and love.
Improve your product with expert UX insights or grow your team's design skills. I offer hands-on consulting and tailored training sessions grounded in real-world product design challenges.
At S&P Global Energy (Commodity Insights), I am part of the product design team. We are responsible for both internal and external platforms.
Apart from contributing to the flagship Core platform, I have had the opportunity to design highly complex, specific domain platforms, such as applications for crude oil wellbore calculations and a system for monitoring gas pipelines in the US, as well as internal platforms for content creation and privilege access management.
At S&P, I have significantly developed my technical and coding skills. I have mastered the design of complex, specific libraries such as AG Grid, Highcharts, TradingView and Ant, taking into account the specific requirements of the data (as data is a key product of S&P).
I am responsible for building and maintaining our design system components library in Figma Make. For some projects, I created fully interactive, vibecoded prototypes that followed the best front-end practices.
