Full-stack product designer —
end-to-end delivery.
Thirteen years across design, engineering, and go-to-market. I take SaaS products from blank canvas to shipped feature — and everything between.

End-to-end UI redesign of Venda ERP — covering user research, information architecture, component-level design system, and production-ready interfaces delivered in close collaboration with engineering.
Scaling a startup from 5 to 200+ people — leading product design end-to-end
Joined SIGE Cloud as an early employee. Led the marketing team first, then transitioned to lead the R&D team — driving product discovery, UX design, feature delivery, and team building through every phase of the company's growth.
Freelance & product — selected pieces.
Tech roots.
Creative soul.
Ships both.
I'm Mateus Frena. I started my career studying systems analysis — which means I've always understood how products are built, not just how they look. Over time I moved into design and marketing, eventually leading both the marketing and R&D teams at a startup I joined when it had a handful of people and watched grow past 200 employees.
That journey taught me every phase of a product: discovery, growth, team structure, technical constraints, and user behaviour at scale. Today I combine that breadth with deep UX craft and AI-assisted development— I'm as comfortable in Figma as I am in a terminal.
I'm looking to join a startup where design is a strategic function, not a finishing step — somewhere I can own the work end-to-end and help the team build something genuinely worth using.
Tools I actually use,
daily, by hand.
Fourteen years,
abbreviated.
I was one of the first employees at a startup that scaled past 200 people. I led marketing first, then R&D. That end-to-end view — from zero to enterprise — shapes how I approach every product decision today.
Started in systems analysis. Moved into art direction. Then marketing. Then product. Now I build with AI. The thread: I always went where the problems were hardest.
