Challenge
The problem I was trying to solve was the disconnect between traditional banking products and young Indian millennials (18-28 years old). Existing debit cards felt generic, corporate, and impersonal. Banking apps showed delayed transaction updates (24-48 hours), had complex interfaces, and lacked features young users actually needed like instant bill splitting, real-time spending insights, and personalized money management. This made financial tools feel intimidating rather than empowering for first-time banking users.
Solution
Designed and launched a unified debit card and mobile banking experience with bold visual identity, real-time transaction notifications, contextual bill splitting, and intuitive spending insights. Created a physical card that users were proud to carry and an app that made money management feel effortless, all while navigating strict banking regulations and physical card manufacturing constraints.
Impact
Transformed how young Indians interact with banking products. Achieved 1M+ active users across Mumbai and Pune, 85% onboarding completion rate (vs. 40% industry average), 4.5★ app store rating with 2,000+ reviews, and 3X industry average for daily active usage. The card design became a conversation starter, driving 60% of user acquisition through organic word-of-mouth and referrals.
01
The Problem
To better understand the problem area, my team and I conducted user interviews, competitive analysis, and ethnographic research observing payment behaviors among young Indians. We interviewed 40+ users across Mumbai and Pune and surveyed 500+ millennials to understand the importance of the problem. Here are some quoted issues faced by the users:
To address these challenges, our goal was to redesign the entire debit card experience both physical and digital from the ground up.
02
The User
The target audience for this product were young Indian millennials and Gen-Z users (18-28 years old) students, early-career professionals, and freelancers who were looking for a banking product that understood their lifestyle. They needed instant transaction visibility, easy bill splitting with friends, spending insights without judgment, and a card that didn't make them feel like they were carrying their parent's bank card. The product was deployed as a mobile-first banking app (iOS and Android) with a physical debit card, available across Mumbai and Pune initially, with plans for nationwide expansion.

My Contribution
Research and Planning
Devised a comprehensive research plan including user interviews, competitive analysis, and usability testing. Planned design sprints and coordinated cross-functional collaboration between design, product, and engineering teams.
Conducting Research
Conducted 40+ user interviews, analyzed 500+ survey responses, performed competitive analysis of 8 debit card providers, and ran usability testing sessions throughout the design process to validate assumptions and uncover pain points.
Designing Physical Constraints
Navigated the unique challenge of designing a physical debit card within strict regulatory requirements (chip placement, bank logos, card dimensions) and manufacturing constraints (CMYK printing, PVC materials). Created 15+ card design iterations before final approval.
Wireframing & Design Concepts
Led the redesign of the mobile app experience, creating multiple screen variations for onboarding, transaction feeds, bill splitting, and spending insights. Collaborated with the design team to ensure seamless integration between physical card and digital app.
Delivery Handover & Collaboration
Provided developers with design specs, assets, and documentation. Worked closely with engineering to ensure real-time notification architecture and smooth handoff for iOS and Android platforms.
Stakeholder Review & Presentations
Conducted regular review presentations with product managers, stakeholders, and banking partners to communicate design rationale, address compliance requirements, and align on business goals.

Conclusion
Thank you for reading! I consider this engagement as one of the most crucial parts of my career. Wyld taught me how to design products that balance bold creativity with real-world constraints regulatory compliance, manufacturing limitations, and business goals. It showed me that great design isn't just about beautiful interfaces; it's about solving real problems for real people. Most importantly, it taught me that when you design with empathy and validate relentlessly, users will advocate for your product better than any marketing campaign ever could. This project shaped how I approach design today: start with questions, not answers. Test early and often. Embrace constraints. And always remember that behind every transaction, there's a person trying to make sense of their money.
