A little about me

Hey, I'm Helder - a product designer with ten years of experience and a genuine obsession with making things feel right for the people using them.


I grew up in Portugal, fell in love with design through print and typography, then got completely sidetracked by technology. That curiosity turned into a career in product design - and eventually drew me to London, where the most ambitious digital products were being built, and where the culture I cared most about happened to live too.


Most of my work has been in entertainment, with teams at NBC Universal, Discovery Inc, and more recently, at Channel 4. I've had the chance to work on products that millions of people use every day to watch, discover, and connect with the stories they love - and that never gets old. I believe good design starts with genuinely caring about people.


I like sitting with a problem long enough to really understand it, and I find that the best solutions usually come from that patience - not from jumping straight to the canvas.


Outside of work, I'm usually somewhere in nature, at a gig, or in the kitchen making something ambitious. All three keep me curious, which I think is the most useful thing a designer can be.


I'm always looking for the next project that stretches me. If that sounds like something you're working on, let's talk.

Channel 4

Senior Product Designer

Currently redesigning the Channel 4 streaming app across iOS and Android, with a focus on navigation, content discovery, and the core user journeys that matter most to viewers. Alongside the product work, I'm owning the app design system - defining the components, patterns, and interaction guidelines that keep the experience consistent at scale.

Channel5 / UI Centric

Senior Product Designer

Led the end-to-end design of Channel 5's streaming rebrand - overhauling the visual language and design system across iOS, Android, Web, and TV as the platform moved from My5 to "5". Alongside the rebrand, I redesigned the Live TV experience and introduced three major new features - Fast Channels, Top 10, and Collections - each shaped by iterative testing with real users.

NBC Universal

Senior Product Designer

At NBCUniversal I designed across a portfolio of TV and cinema brands - including Syfy, Studio Universal, and Hayu - delivering high-fidelity UI and interactive prototypes across TV and web platforms. It was here I developed a real feel for designing experiences that serve strong editorial identities without getting in their way.

Pixelmatters

Co-founder & Product Designer

Before moving to London, I co-founded Pixelmatters in Porto - a digital product studio born from the conviction that the city deserved better design. It was my first real lesson in building something from scratch: finding clients, shaping a design culture, and learning the full product lifecycle from both sides of the table.
