Hi, you can call me May.
I turn messy, high-stakes problems into products people trust.

I zoom out first and map the system, its constraints and its risks. Then I zoom in with discovery that mixes interviews, surveys, analytics and complaint analysis, and I turn what I learn into journeys, flows and design systems that engineering can build and scale.

Teams usually hand me the discoveries that pull from many data sources and many points of view. I turn those into clear journeys, priorities and a roadmap the team can execute.

I use AI as a thinking partner. It helps me explore more options, stress-test ideas and explain complex concepts in simple words. I prototype AI assistants such as Guia da Bolsa, a multi-agent mentor for new investors, and I built an orchestrator agent for a Growth team's workflow at TOTVS. Through micro1 and Mercor, I also evaluate AI-generated designs, workflows and writing for frontier AI labs.

   TOTVS · RD Station

   Senior Product Designer

   TOTVS is the largest technology company in Brazil, and RD Station is its B2B SaaS for marketing, sales and CRM. On the Expansion squad I design add-ons, cross-sell and upsell across three products.

   What I did

   • AI sales copilot landing pageI diagnosed why an AI copilot for sales conversations lost visitors before they interacted. Session data showed dead clicks on feature explanations and unclear pricing, so I rebuilt the page around demo videos, a how-it-works section and pricing personalized by CRM plan, and implemented it in Cursor with the design system.
   • Agentic flow for Growth experimentsExperiments were slow across 15 stages. With a multidisciplinary squad I reorganized the flow into four human decision points, with AI running the steps in between. I built the orchestrator agent that takes a defined problem and returns design-system screens, validated copy, accessibility checks and engineering specs. It states which tools it will use and which it skips, and it keeps three checkpoints with PMs and designers.
   • Market benchmark skillI wrote the skill that collects public evidence with sources, separates facts from interpretation and closes every report with what the research does not answer.
   • Web PhoneI designed the full calling experience inside the chat, from the active call to error states, plus transcription, an AI summary and recording download. Because calls carry a cost, the activation and upsell gates show it upfront.
   • Cross-sell across three productsI moved the focus from placement to user pain. Support tickets, NPS requests and multi-product use cases showed where one product already solved a problem for another.

   micro1 and Mercor

   AI Training Expert · Freelance, remote

   I evaluate outputs from frontier generative AI models for one of the world's largest AI companies, under NDA. My work covers AI-generated designs, workflows and writing quality.

   What I did

   • Design artifactsI audit AI-generated decks and visuals against written design instructions, covering typography, layout, hierarchy and how closely the result follows the prompt.
   • AI workflowsI compare workflows built for specific professional roles and judge which one delivers more value, looking at connectors, output quality and how much control stays with the user.
   • Writing qualityI spot AI slop at the phrase level and rate writing with written justifications that quote the exact evidence.

   Asaas

   Senior Product Designer

   Asaas is a Brazilian B2B fintech for payments. I led the redesign of Pague Contas, its bill payment product, with a product and UX audit and a vision for AI-assisted payment automation.

   What I did

   • Pague Contas redesignI unified bills from every source in one list, cut the actions on the first layer and clarified statuses so people decide and finish faster.
   • Payment automation centerI designed the hub where people activate and manage automatic bill capture and the entry points to the financial copilot.
   • Adoption and researchI synthesized tickets, social feedback, audits and surveys, and worked with Growth on in-app triggers and email campaigns to close the adoption gap.
   • Bill recovery and schedulingI introduced clearer states, kept canceled bills visible and let people re-pay or edit a scheduled payment before canceling it.

A few words from managers, peers and partners I've worked with.

• Anonymous reviewTeam member, OCA Uruguay

  May is a reference when it comes to customer experience. Always open to new ideas, she has a 360-degree vision of the problem that needs solving in each project. On top of that, she's someone who genuinely cares about the team's success and ownership. She transmits trust in the work she does and always delivers in the most complete and thoughtful way possible.

• Renata T.Community Leader, Customer Onboarding, OCA Uruguay

  A large part of OCA's digital evolution this year has May's fingerprints on it. She was involved in the most critical projects, always contributing collaboratively, efficiently, and with complete focus on the customer. Her attention to detail and organization are true differentiators. She consistently gives her best and is always thinking about the sustainability of both the business and the design discipline.

• Leonardo B.Team member, Itaú's investment community

  May is incredibly committed to everything she sets out to do. She had a huge learning curve in the investment domain, but quickly stood out by bringing sharp questions, aligning expectations, and offering both technical and strategic input. She leads initiatives like the investment PIX almost entirely on her own and handles everything with great time management. Her combination of soft skills and autonomy make her one of the most well-rounded designers I've worked with.
