Guilherme Fernandes
Senior Product Designer
I’m a full-spectrum product designer with 5+ years in product design, 9+ in tech, including past hats as co-founder, product manager and digital marketer, having started my career as a researcher.
I have international experience and I’m comfortable working remotely in agile global teams, relying on strong communication skills and used to collaborating in scrum teams with all kinds of stakeholders.
With a diverse background, I thrive at the intersection of design and strategy, where design goes beyond shaping interfaces to influencing the strategic direction of a product.
I’m experienced in telco, internal logistics tools, proptech and fintech, for both mobile and web products.
I’m biased towards making sure there are always solid reasons behind every product and design decision.
Growing up in Porto, Portugal, I learned from my parents an aptitude for critical thinking and creative problem solving. I also have an insatiable desire to learn new things and a healthy addiction to Reddit (go figure!).
My early coding experience at 12 (I launched my first website), a passion for web design and technology (back in the days of Macromedia Dreamweaver & Flash), together with an MSc in Psychology, allows me to have a holistic approach to product discovery.
It also lets me comfortably speak the language of users, product, engineers and stakeholders.
I’m always challenging myself to learn new things, be a pioneer and explore new design opportunities.
