✓ +163% registered users (80k → 237k)
✓ 68,000 vouchers sold in the first month
✓ Strong early adoption validated product demand
Problem
Users needed a fast, intuitive way to purchase vouchers online despite:
- multiple voucher types
- variable quantities
- purchases on behalf of dependents
The solution had to be lightweight, simple, and deployable quickly.
Key Challenges
Constraints: Limited infrastructure, tight deadlines
Information scarcity: Minimal meetings to define complex functionality details
Approach and Key Decisions
Research & Analysis
Held intensive stakeholder meetings focused on bond acquisition types, while auditing public entity portals to gather and cross-reference all necessary regulatory information.
UX & Information Architecture
Iterated through multiple diagrams to define family vs. individual bond views. Designed distinct flows for purchase history and multi-purchase features to reduce user friction.
UI & Visual Design
Balanced visual aesthetics with GeneXus technical constraints and tight deadlines. Optimized core components like buttons and color palettes to ensure a fast, functional implementation.
Product Collaboration
Collaborated with the Project Lead and the client to iterate on key details and align expectations. Conducted final reviews to ensure a seamless handoff before independent development began.
Designing for speed and clarity
Given constraints, I focused on:
essential functionality
minimal flows
performance-friendly UI decisions
Supporting real purchase behavior
Initial designs assumed single voucher selection.
After feedback, I redesigned the flow to support:
multi-selection of voucher types
quantity adjustments
real-time subtotals
Flexibility during development
Ongoing collaboration with engineering allowed me to adapt designs while preserving core product value under technical constraints.
Learnings
Simplicity often emerges through iteration, not initial ideas
Tight deadlines require decisiveness and focus on core value
Despite some initial technical issues with the payment method that led to negative reviews, users found the feature to be a significant and positive improvement
Opportunities for
Improvement
Stronger error states and microinteractions
More robust user testing and success metrics
Better alignment between digital product and service-side adoption
