User & experience outcomes

Outcome one

Describe a user- or experience-level result and why it mattered.

Outcome two

Describe a second user- or experience-level result and its impact.

"This wasn't just a component library. The value came from winning support for an investment some stakeholders doubted, learning from a system already live in production, resolving a structural problem inherited from atomic design, and keeping two very different products coherent under one family."
Business & team impact

Impact one

Describe a business- or delivery-level impact.

Impact two

Describe a second business- or team-level impact.

What people say about working with me

ATAna TeixeiraSenior Principal Product Manager @ Oracle | PhD in Computer Science | Nurturing products at the interface of biology and technology
“Inês is an exceptional user experience researcher and designer. Her dedication to creating a seamless and intuitive experience coupled with the relentless explorations and optimisation of the use of existing design patterns has not gone unnoticed.I worked with Inês on the development of an interface and user flow for a brand new product to support complex research processes for genomics data processing. Her work was crucial in triggering discussions on the technical implementation and her prototypes made several conversations much easier. Inês did not limit herself to just design a like-to-like user experience based on the product team prototypes, she wanted to understand the user needs and translate that into an interface that not only met the needs but exceeded expectations. Inês would iterate over and over again with feedback from product, from users, from engineers and from her own team, I've never seen Inês frustrated by this. Inês was a quick responder, acting fast with a basis for our work and then iterate over and over until we were all satisfied with the result. We worked at the transition between design systems, Inês embraced the challenge with both arms and always ensured constant feedback back to other teams about challenges or usability findings.Inês led the work without ego and made it truly a co-design experience while putting users at the centre. Inês was always prepared to cover for others and putting additional effort at the cost of her own personal time to drive the work forward. Moreover, the collaborative spirit and professionalism demonstrated throughout the design process have been invaluable for me personally. Inês was always very transparent in her communications and ensured she brought all stakeholders and cards to the table so that the best decisions could be made collaboratively.Inês is an inspiration for me and for the colleagues in her team, she truly cares about her work and doing better everyday.”
JBJared BaumPrincipal User Assistance Developer at Oracle
“Any software development team fervently hopes for a UX designer like Inês. I was very fortunate to work with her in the early stages of a project, where we were defining and adjusting the UI text for several different workflows. Frequently, our conversations led not only to the best placement of in-application content, but enhancements to the design itself.Inês' superpower is the ability to simultaneously hold deep technical nuance of the product, consistency of design standards, and the ability to improvise, while making it all look effortless. She is a great communicator, and conveys her ideas gently, thoughtfully, and thoroughly. She is also an excellent leader who brings people to her understanding by showing, not just telling.I would relish the opportunity to work with Inês again, and cannot overstate my informed opinion that she would be an incredible asset to any organization.”
