Professional summary

Senior Product Designer with 6+ years of experience building digital products across Gaming, Esports, EdTech and Telecommunications. Specialized in Product Discovery, UX Research, Design Systems, Product Strategy and end-to-end Product Design.

Throughout my career, I have worked on B2C digital products, consumer platforms, online communities, educational products and esports experiences, helping companies transform user needs into scalable product solutions aligned with business goals. I use AI optimizations to improve my workflow, improve research, and guarantee quality deliveries.

I currently work as the Founding and Sole Product Designer at Esplay, Sweden's largest native CS2 esports platform, where I am responsible for Product Design, UX Research, Design Systems, Brand Experience and Product Strategy supporting more than 130,000 registered players. Here, I led initiatives that contributed to significant product growth and engagement improvements.

Before that, I designed digital products for EdTech and Telecommunications companies, including products used by more than 60,000 users in the education sector and consumer-facing digital experiences in one of Brazil's largest telecom organizations.

I am particularly interested in solving complex customer problems, building scalable product ecosystems, improving user experience through evidence-based decision making, and connecting design outcomes to measurable business impact.

If you're looking for a Product Designer who can contribute from discovery through delivery while balancing user needs, technical constraints and business goals, I'd be happy to connect.
