Maximizing Customer Release and Funnel Fluidity.

Registration (Growth)

Jan/23 → Mar/24

The Registration team, part of Nubank's Growth BU, owns the customer acquisition funnel, managing data collection for account opening, including personal/financial data, identity validation (liveness), and initial product setup.

My core focus was to execute a strategic architectural overhaul of the funnel to maximize conversion metrics, integrate strategic high-value products and improve overall funnel stability and robustness.

Context

The primary challenge was resolving technical debt and user friction that caused high drop-off rates and sequential, slow customer release jobs.

My goal was to redesign the flow to be fluid, fast, and robust by consolidating, parallelizing, and optimizing key steps, thereby significantly reducing Time-to-Activation (or Time-to-Release).

The design strategy focused on three major threads: Flow Parallelization, Strategic Product Integration, and Conversion Rate Optimization (CRO).

Key Deliverables & Impact

My work directly contributed to significant improvements in overall conversion metrics and funnel stability by resolving major technical and experience gaps.

A. Strategic & Architectural Achievements

✎ Flow Parallelization (Product Setup): Led the architectural redesign to restructure the funnel, separating mandatory info collection from initial Product Setup. Designed transitional experiences that allowed heavy operational work (e.g., Fraud/Ops Validation) to run in parallel with user input, immediately reducing Time-to-Release.

Due to the complexity of dealing with legacy code and the critical importance of this flow for user acquisition, the project required 5 iterative design phases to reach the final solution, ensuring technical feasibility while maintaining optimal user experience.

The implementation drove an uplift in the overall Ordered-to-Activated metric, maximizing customer releases.

✎ UV Bundle Integration (Premium Product Adoption): Designed the inclusion of the Ultravioleta (UV) premium account bundle—previously only for existing customers—directly into the acquisition journey.

Given the product's strategic importance, this initiative required extensive stakeholder management and cross-team alignment across Product, Engineering and Marketing teams to ensure seamless integration.

Successfully integrated this high-value strategic product early in the process, setting the architectural stage for future multi-product integration and driving early adoption.

B. UX Robustness, Quality, and Inclusion

Focused on stabilizing the funnel by designing and validating high-impact micro-interactions, robust error-handling, and accessibility solutions.

✎ Conversion Rate Optimization (CRO): Executed the Gmail Redirect test using Google Single Sign-On, which allowed users to instantly verify their email, eliminating the manual step of switching apps and reducing drop-off. The Initiative resulted in significant increases in core conversion rates.

✎ Funnel Robustness and Data Quality: Redesigned major generic error screens to allow affected users (due to network or backend issues) to gracefully re-enter and continue the flow, resulting in a major conversion uplift.

Designed solutions to prevent incorrect data entry (e.g., unaccepted characters in address fields) and partnered with Logistics to improve the Address input flow, significantly reducing card delivery problems caused by bad data quality.

✎ Inclusion & Accessibility Overhaul: Redesigned the Screen Reader experience for the photo capture step ("Take Photos") to ensure the flow is fully usable and inclusive for visually impaired customers.

Designed the flow to correctly collect the customer's Social Name during registration, ensuring legal and inclusive data capture.
