Accelerate Your UI Development

Your Challenges

Are you a Director about to embark on a significant modernization project for a web application? Are your web products’ UI and UX fragmented? Do you keep getting inconsistent deliverables from developers when you request front-end features?

Often, we are so pressed for time that we want to see something coded urgently. We don’t take the time to plan things out, afraid that we are going to end up in analysis paralysis. We tell ourselves, “we’ll figure it out,” as we force development teams to produce something tangible. And then, when we finally implement an interactive experience that is somewhat “usable,” we need to scale and improve it. However, the look and feel of the application is not consistent because developers just did copy-&-paste of styles or components that are hard to update.

It’s like building a house without a blueprint.

To call Guillermo a rock star among rock stars is no overstatement. I had the distinct pleasure to work with him at Visa for a number of years on projects from small two-person efforts to large global deployments where he managed cross-functional teams. At every size, he always had a level of dedication and professionalism to his leadership that was the envy of any team that he led. Additionally, Guillermo has the unique ability to drive a product or process to completion while at the same time maintaining and growing the respect of his team and business stakeholders. It was an absolute pleasure working with Guillermo and hope to do so again in the future.
