The white label mobile wallet is a modular fintech platform designed to support fast, secure and compliant digital payments. It works as a Wallet as a Service solution for e money companies, marketplaces and banks. The product gives clients a ready to launch foundation along with flexible modules that can be added on top for local needs.

The system is used by companies in Europe and Türkiye, where regulation and user expectations vary across markets.
My role
I focused on defining the structure of the wallet and shaping how the product should work for different markets.
- Led market research and benchmarking across Europe and Türkiye
- Defined the core features and the extension layer as two separate capability groups
- Worked on product positioning, messaging and user flows
- Designed customer personas and clarified key use cases
- Supported UI and UX direction for onboarding, payments and transfers
- Planned the roadmap, organized JIRA work and cleaned the backlog
- Wrote documentation for internal alignment and external onboarding
- Analyzed regulatory needs (KYC, AML, limits, GDPR) and reflected them in the product
- Worked with engineering to keep the modular structure consistent
Key contributions
- Helped establish the wallet as a modular fintech engine instead of a single app
- Designed a clear two layer structure: core financial engine and customizable capabilities
- Improved user flows for payments, P2P, QR and onboarding
- Supported company wide understanding of European and Turkish compliance needs
- Improved feature clarity through better documentation and product messaging
- Strengthened alignment with sales, engineering and leadership
- Created a cleaner roadmap and more focused development plan
Product architecture
The wallet follows a layered design:
- Core Layer: Accounts, ledgers, KYC, compliance checks, transaction engine
- Extension Layer: QR, NFC, loyalty, P2P, card modules, campaigns, regional add ons
- UI/UX Layer: Modular front end structure for iOS and Android
- SDK Layer: Secure components and reusable building blocks
This architecture helps clients launch quickly while keeping the product flexible for new features.
Impact
- Faster time to market for clients launching a branded wallet
- Clearer separation between core financial logic and optional modules
- Stronger compliance alignment for TR and EU markets
- Easier developer collaboration due to a modular, documented structure
- Better product adoption thanks to clearer flows and messaging
Notable decisions or constraints
- Needed to support many capabilities without making the core heavy
- UX had to stay simple while handling a large set of financial actions
- Compliance requirements shaped onboarding and transaction flows
- Payments and P2P logic had to be both modular and stable
Summary
The white label mobile wallet became a flexible and scalable platform built on a clean core and customizable features. It helped companies launch secure digital payment experiences while adapting to market specific needs.
