Hola! I’m David Portilla. 👋

I am a frontend developer who enjoys creating experiences that bring value to the business and delight users.


I have extensive experience working as Frontend Javascript Developer with strong abilities in UX and accessibility (a11y).

Design services and develop products are my deeply passion. I’m a foodie, a constant learner and a soccer fan. I never stop learning, I read to feed my mind and travel frequently to inspire myself with each culture.

I am a team player; throughout I’ve led design and development teams. I’ve collaborated with friends, entrepreneurs, and companies to fulfill their dreams with projects such as ecommerce,  web portals, mobile applications and interactive products.

I have been an entrepreneur, I have triumphed, and I have also made mistakes … however, I have never stopped working to reach my dreams!


My powers

Product design Service design Frontend development UX design Wordpress development User Flows & Scenarios Wireframes & Prototypes

What I love and do

I participate actively in creative problem-solving processes, using design and innovation methodologies to achieve memorable experiences.

I don’t make websites I do service and product design!

I deliver products that point to the growth strategy of the business always having in mind a user-centered approach to solve the challenges of my clients in digital environments.

My process starts with the discovery of needs, knowing the users and thinking about the product strategy. Then designing the user experience with a clean interface and efficient frontend development.
