Hi! I'm Daleska. Product designer & UX educator.

For 9+ years I've designed end-to-end experiences for brands like Salesforce, UBS and Banistmo. Today I design A/B test variations at Speero and teach UX at the University of Costa Rica.

Some projects I've worked on.

Right now I design A/B tests at Speero.

I also teach UX.

At the University of Costa Rica, in the UX Design licentiate program.

A bit more about me.

Salesforce Partner Community

I led the redesign of the portal Salesforce partners use every day, and tested each part with them.

Partners couldn't tell what needed their attention.

The portal showed everything at once. The job was deciding what to keep, rename or remove.

I tested every part while designing it.

Four short studies with real partners and a Figma prototype.

What partners told us.

I mapped the findings with the team.

It helped the team agree on the problem before designing anything.

Three better versions of Navigator in one week.

With RITE testing, I fixed the prototype between sessions.

What I changed and what I left for later.

97% of tasks completed.

10 partners, 7 tasks in Customer Success. "I like how I can gain a little more visibility."

The final design.

Built on Salesforce's design system.

I followed the Salesforce Lightning Design System to the letter, pixel perfect. The portal feels like the rest of Salesforce, and engineering could build it as designed.

My best decisions came from listening to partners and taking things out.

Banistmo Digital Banking

Making everyday banking clearer for people, businesses and the bank agents who serve customers in their neighborhood.

Each product worked in its own way.

Every app had its own menus and names. People needed one clear way to bank on any device.

I reorganized every service into three menus.

I mapped every service in the current apps, level by level, and grouped them by what people came to do.

From paper to wireflows to screens.

I designed the visual UI too, but those files stayed with the client. Here I show the UX work behind it.

Sign-up in three steps, with a way out on every screen.

Two people, one transaction.

Bank agents (CNB) are local shops where people can withdraw cash, deposit or pay. The agent uses the app, and the customer only steps in for the card and PIN. Many agents are Chinese-Panamanian, so the screens are in Spanish and Chinese.

I helped build the design system from scratch.

The app, the web branch and the agent app had to feel like the same bank, so the team and I made one set of components, styles and patterns for all three.

The UI library stayed with the client, so I can only show its structure here.

Some of the flows I designed.

These are five of them. There were more, shipped in packs so engineering could start building while I kept designing.

In banking, people trust small details, like knowing which step they're on or getting a clear receipt.

Pride Unstoppable

When COVID-19 cancelled the 50th San Francisco Pride Parade, I designed a step counter for the Golden State Warriors app, and fans marched from wherever they were.

What does Pride look like when not everyone can march?

The world was changing every week while I designed. I kept checking the news and adjusting the idea.

From "we march for the ones who can't" to "walk for what you care about."

The first concept came from Shackleton, an agency in Chile. I turned it into an action, where every step you walk counts for a cause. The logo arcs follow the history of the Pride flag.

A small feature inside the Golden State Warriors app.

Fans find it from a banner on the home screen. Everything starts from the step counter.

Every step paints the rainbow.

The rainbow ring fills up as you walk. There's no finish line, so even a short walk counts.

Pick where you march and why.

Fans choose a Bay Area community or a continent. When the Black Lives Matter protests grew, I added anti-racism as a second cause.

Version 2 added history and sharing.

With a sensitive topic, I learned to listen first. Research and open talks with the team made the design better.

My work at Speero

Speero helps brands test and improve their websites. I'm one of the designers. I work every day with strategists, analysts and developers, and my part is the design.

Below, a real test file with the client's brand hidden.

UI design is most of my work, but not all of it.

A different client almost every day.

Clients change during the week, and each team works its own way. Some want rough ideas, others want final screens that I review with their developers. It has made me quick to adapt, and I like that.

Each client, in one place.

Every client has its own brand, components and rules. With Claude I've built around 14 design systems that keep all of that in one place. When a new test comes in, I start from the right colors, type and components, so my time goes to the idea and the details.

How a test moves through the team.

Each test goes through several people in different countries, and a project manager keeps it on track. I work close to the CRO side, but I'm the designer. I don't run the analysis.

How I run a UI audit.

I helped put this method together with the design team. We work on a shared Miro board and finish with a short report for the client.

Teams I've designed for.

One day I'm doing pixel-perfect screens with a client's library. The next I'm sketching ideas for a strategist. Switching that often taught me to adapt fast.

How I teach UX

I teach UX by using UX. I treat each course like a product and my students like its users, so I keep testing it and making it better with them.

The course is one big project.

Students work on the same project all semester and deliver it in parts every two weeks. Each part uses what we just saw in class, so the topic is still fresh.

Retrospectives, like in a sprint.

Three times each semester, students answer an anonymous retro. I read every answer and adjust the course while it's still running, not only at the end.

What students value most.

When I ask what went well, these are the things students mention again and again.

Anonymous answers, translated from Spanish.

They learn in the same tools they'll use at work.

Each course lives in one FigJam board, and students design in Figma. By the time they start their own projects, these tools already feel natural.

The basics, with a first real project.

Students build their first portfolio piece and finish with "My first UX project", using what they learn each week.

Thesis projects and a new curriculum.

If my students get stuck, I treat it as a design problem I can fix. That habit makes me a better designer too.

All projects

Work for 20+ brands at Accenture, Speero and as a freelancer.

Three projects, in detail.

Other projects at a glance.

Most of this work is under NDA. I'm happy to walk you through any of it in a call.
