About
Cashway is a fintech providing digital solutions for credit unions and financial institutions. The core app is a white-label solution, enabling each client to apply its branding and deliver personalized financial services.
As Product Designer, I led the PIX implementation and accessibility requirements in a white-label app, ensuring usability, regulatory compliance, and visual consistency.

My design process
To implement PIX and accessibility, I applied a user-centered approach while addressing Central Bank regulations. I followed Nielsen’s usability heuristics and Design System principles to ensure consistency and scalability.

Flows for PIX functionalities
I designed complete user flows for PIX functionalities. To support adoption, I also developed educational micro-onboardings for critical features like PIX Withdraw/Change and My Keys. In addition, I modeled error scenarios and system feedbacks to ensure user clarity and prevent friction during transactions. Throughout the process, I worked closely with backend and frontend developers, aligning technical feasibility with design consistency.
01.
My PIX Keys
Designed the registration and management flow for PIX keys, including a 3-step onboarding to explain function, types, and limits. Users could register, verify, delete, copy, and share their keys easily.
(15 screens + 3 onboarding)

My PIX Limits
Modeled the management of PIX limits, including day/night periods, withdrawal & change, registered accounts, and time controls. Users could also request higher limits with justification, receiving clear feedback about the financial review.
(25 screens)

Send PIX
Created the complete flow for sending PIX, with an introductory onboarding highlighting its benefits. Users could send via key or bank data, schedule or send instantly, review details, authenticate with password, and access a shareable receipt.
(20 screens)
01.
PIX Copy & Paste
Simplified the experience of sending via “copy & paste,” where users insert the code, review transaction details, authenticate, and receive a shareable receipt.
(5 screens)

PIX with QR Code
Designed the experience for scanning QR Codes, with clear camera permissions, scanning, transaction review, authentication, and receipt confirmation.
(5 screens)
01.
PIX Billing
Created flows for standard and advanced billing. Users could define amounts, due dates, interest/fines, discounts, and debtor info. Each billing generated a QR Code and link, and the management area included filters and status tracking.
(16 screens)
01.
PIX Withdrawal & Change
Designed a 4-step onboarding explaining how to withdraw cash in ATMs/merchants and withdraw along with purchases (change). Location access enabled a map and list of establishments. The withdrawal process integrated ATM steps and generated receipts.
(20 screens)
Help
01.
Provided a direct channel with the responsible bank and an official link to the Central Bank, ensuring quick and reliable user support.

Accessibility
Accessibility was a core pillar of this project. While developers were building the app’s foundation, I focused on ensuring all accessibility requirements were met from the first version.
What I did:
Research & Foundations
Conducted a study on visual accessibility following WCAG and Apple/Google Accessibility guidelines.
Collaborated with devs to explore native accessibility tools available on iOS and Android.
Built a requirements checklist to track compliance with accessibility standards.
Visual Adjustments
Dark Mode: reduced brightness, improved night readability, minimized eye strain, and optimized battery usage.
Color Contrast & Branding: verified all client branding palettes met minimum contrast ratios (WCAG AA/AAA). For each client, I adapted and documented the full color system (including HEX codes) to ensure consistency.
Typography: enabled user customization of font size and style to improve legibility.
Motion & Interaction
Added the option to reduce animations for users sensitive to motion or screen transitions
Modeled error states and system feedbacks to ensure clarity for all users, including those relying on assistive technologies.
Screen Readers & Testing
Tested the app with screen readers
Verified alt text and semantic labels to guarantee correct reading order and meaning.

Insights & Outcomes
Summarizing the impact of the project, highlight key learnings, and reflect on my contributions, insights that will guide future design challenges.
1
I led the implementation of PIX flows in the app, focusing on usability, clarity, and regulatory compliance. Internal team tests and cross-functional feedback (Marketing, HR, Support) ensured smooth, intuitive experiences.
2
Aligned with stakeholders (Manager and CFO), we refined key features like maps and listings for PIX Withdraw/Change, then proceeded to collaborative development and pre-launch testing, delivering on time for the official PIX launch in Brazil.
3
During 4 months, I maintained continuous research and documentation, structured the backlog for V2, and adapted branding and screens for new clients. I also created new screens and components for the Design System, ensuring consistency and scalability.

This project strengthened my cross-team collaboration, UX expertise, and financial product knowledge, resulting in a flexible, educational, and user-centered PIX experience.
