I'm Oswaldo Miguel and I'm an experienced UX/UI Designer. In 10 years, I have worked in 7 digital products and 2 games. I specialize in boosting businesses by understanding its users.

Compañero Electricista

(An app for electricians, simple to use even under sunlight and wearing gloves)

My role: It's my own project. I scoped the three tools, prepared the content from the official regulation and real price lists, designed it, and built it with AI coding agents.

Precio del Alquiler

(Real rent prices by address, for renters in Catalonia)

My role: I came up with it and run it with Arthur Nunes. It helps renters find out if their rent is fair and what their rights are. I designed the main screens and created Claus, its design system.

Loggi Leve

(B2B2C logistics technology. Fancy!)

My role: As UX Strategist, I led strategy and research during the product's scaling stages, managing the design team. I traveled to remote Brazilian cities to understand users and ensure our app worked well everywhere.

Stuart's internal TMS

(Also logistics, but with the typical dream of combining four products into one)

My role: As Lead Product Designer, I managed the design team while working closely with the CPO and COO to replace legacy software. We balanced addressing daily challenges with moving toward the company's future vision.

I'm not into keeping things on paper; the work I'm proud of is the one that is in the real world. Cutting things out of scope, adding new ones in when needed, sticking to the plan but also adapting as we go. That's what I like, and that's how being a designer makes sense for me.

Constraint is the mother of innovation.
