About me

Nice to meet you!

I’m a product designer with hands-on experience on the design and development of all kind of digital experiences. I graduated as an industrial design engineer in 2015, and while studying I became a self-taught graphic, web and product designer and programmer I have been crafting websites, brand identities, user interfaces, and artwork designs for more than nine years now.

I love building things from scratch, from the initial research to the final delivery, I learned both design and programming to be able to create digital products all by myself. And still today I can’t stop learning new languages and software in order to improve my skills.

When I’m not in front of a computer designing or learning about design, you can find me travelling the world or exploring my passion for photography. I’m based in London but I consider myself a digital wanderer in a journey to create better products by learning how different people around the world live their lives.

If you want to know more about me or have an overview of my whole professional background, have a look at my resume on the top of the page.

UX/UI design

As a maker, I enjoy building products from end to end. I specialise in the design of digital products of all kinds, from a corporate website, a new product platform or a web-app based product, I specialize in designing fully complete designs, from its initial user research, wireframing, prototyping and defining the final high fidelity prototype and its design system.

Brand design

Apart from being usable, a product needs to be visually appealing, not only in the sense of being attractive but also as in line as possible as the trends of the market where this product is going to be launched, the visual appearance of a brand or product need to consist, representative and have the right character. I specialise in building grand guidelines and visual identities.

Research & Testing

When I’m not designing, I’m always trying to help in the creation of a product, either performing user research, competitor analysis or exploring the user behavior. Not only that but I’m always learning new things and thanks to my technical background I can always jump into a development task and make amendments to the code of the front end of a site or in the CMS.

*While I’m usually based in London, I started a journey as a digital nomad in 2018 and you can find me working remotely while exploring the world at least a week every month. Helping me get out of the rush of the big city and learning about other people’s behaviour and ways of living. You can learn more about it and how it benefits my career by reading this blog post.

About me

Knowledge is power, and so it’s experience.

Over these more than nine years I have been working as a designer, I have been mastering a few design skills, programming languages, art and development abilities, and also project manager and client-facing knowledge that has helped me achieve and succeed on every project I’ve worked.


What started as a side-gig while studying my engineering degree became my passion over the years and after finishing uni I decided to focus my career solely on digital product design. Starting building websites, identities and artwork for music brands and as a consultant for music record labels, I, later on, joined a few design agencies to focus on the digital transformation of SME and startups building online platforms and applications and currently working on the gaming industry redefining user experiences. Seeking always for new challenges and ways to solve problems and tell stories using the digital world.


Even though each project is different, I usually follow the same steps to ensure the success of the execution, from an initial market research, stepping into the definition of the requirements from both the user and the business perspective, to an initial brainstorm of ideas that will conform the project, moving to a rough low fidelity prototype that is tested with an small group of users, helping iterate and improve what will become the high fidelity prototype together with its design system and finally preparing the final prototype to be build by creating the documentation and design files to be handed over to developers.


When a project needs to be executed by multiple people, some with specific responsibilities and forming part of specific teams, either product, engineering, marketing or management, and over the past few years I’ve been in charge of ensuring that the communication flows between the team members and things are done before deadlines and deliveries, both from the design perspective as the union between product and engineering and as the one overseeing the development process. Sometimes taking special ownership of each team, having to manage multiple designers or overseeing the work of the developers before showcasing the project to stakeholders.


During the past few years and because each project is different, I’ve had the chance to work and master multiple tools and programming languages that have helped me build better products. From design and prototyping too, to project manager and of course different CMS, e-commerce and web creators to help me deliver the best results using the latest software.
