Development of a Multi-Brand Digital Lending FinTech Ecosystem(NDA)
FinanceA case study of long-term support and development for an ecosystem of four independent online lending web services: a shared backend core, frontend stabilization, design system reconstruction, and infrastructure modernization.
Overview
FinTech / Digital Lending • Web Platforms • Support & Development • Infrastructure Stabilization • 2022 — Present
An ecosystem of four independent web services in the online lending space:
- •4 separate domains • 4 independent frontends
- •Shared backend core
- •Common application processing and integration logic
Our role was to act as a long-term technical partner responsible for product growth and operational stability.
We are responsible for:
- Frontend development and UX improvements
- Implementation of new features
- Design system reconstruction in Figma
- Infrastructure modernization
- DevOps and security
- Production support
What the Platforms Include
Each of the four platforms is a full-featured web service for applying for financial products online:
Public-Facing Layer
- •Marketing landing page and product calculator
- •Application funnel
- •Legal documentation and partner integrations
Customer Account Area
- •Registration, authentication, application forms, and document uploads
- •Scoring process and decision delivery
- •Management of active products and transaction history
- •Payments, extensions, notifications, and status tracking
System Layer
- •External service integrations
- •Application processing and payment gateway interactions
- •Anti-fraud checks and partner channel workflows
Each platform has its own visual identity and marketing strategy, while running on a shared technology core.
Business Goals
- Ensure stable production performance across all services
- Bring the infrastructure into a controllable, manageable state
- Improve the user journey and conversion rates
- Systematize design and interfaces
- Accelerate rollout of new functionality
- Minimize incidents and downtime
What We Delivered
Frontend Stabilization
- Support and development of HTML / CSS / JS codebase
- Refactoring of outdated UI solutions
- Improved responsiveness and cross-browser compatibility
- Optimization of client-side logic
- UX improvements at key funnel stages: application flow, account area, payments, and error handling
User Journey Optimization
- Form structure and status display logic
- Clearer visual hierarchy and better user feedback
- Microinteractions and contextual hints
The result was a clearer funnel and reduced user frustration during the application process.
Design Reconstruction and Systematization
Original design files were unavailable. We:
- Rebuilt interfaces in Figma
- Created a design library
- Unified UI components
- Standardized the approach for new pages and features
This helped accelerate development, reduce UI inconsistencies, and create a scalable foundation.
New Feature Delivery
- New sections and product hypotheses
- Changes required by regulatory updates
- Integration enhancements and partner-specific flows
All work was delivered in close collaboration with the client’s backend team.
Infrastructure and DevOps
Comprehensive infrastructure modernization included:
- Server environment updates and environment stabilization
- CI/CD modernization
- Secure access, SSL, and protected connections
- Backups
- Incident diagnostics and resilience monitoring
The result was a predictable, controlled environment instead of reactive firefighting.
Key Challenges
Shared Core, Different Brands
Every change had to work correctly across the entire ecosystem
Legacy Solutions
Parts of the codebase and infrastructure required careful modernization without interrupting live services
High Stability Requirements
In financial services, availability, data integrity, and security are mission-critical
Multiple Integrations
External API dependencies required carefully managed changes and strict compatibility control
How We Work
Methodology: Agile + service-based support
Process:
- →Task intake → Analysis and estimation → Planning
- →Implementation → Testing → Release → Monitoring
Every change goes through:
- Impact assessment across all 4 platforms
- Compatibility validation with the shared core
- Regression testing
- Post-release monitoring
Results
Stable operation across all four web services
Reduced number of incidents
Structured, manageable infrastructure
Faster rollout of new features
Improved user experience
Better project governability
More predictable releases
Team
What We’re Proud Of
Summary
This project is an example of complex delivery within a multi-brand FinTech ecosystem, where our team acted not just as an implementation vendor, but as a technical partner.
Today, four independent web platforms built on a shared software core operate as a stable, scalable, and manageable system — with improved UX, structured infrastructure, and a sustainable delivery process.
