Our client, a leading digital ledger and business management app similar to Khatabook, approached us with the goal of transforming their existing proof-of-concept (POC) into a fully scalable, user-friendly platform ready to support millions of users. The app provides MSMEs (micro, small, and medium enterprises) with tools to manage transactions, monitor cash flow, and receive payment reminders. With the POC established, the client needed a scalable backend, an enhanced user experience for mobile and web, and an improved real-time notification system to support growing customer demand and drive engagement.

Major challenges include seamlessly navigating intricate compliance regulations, current legacy systems, addressing data security concerns, and delivering seamless integration across platforms. Time sensitivity added another layer of complexity.
Platform Scalability
The POC infrastructure faced significant performance degradation under high user loads, impacting critical operations like transaction tracking and balance updates. The architecture required complete redesign to support millions of users while maintaining optimal performance.
User Experience Design
The platform's basic interface and cumbersome navigation created significant user friction across web and mobile applications. A sophisticated, intuitive design was essential to drive user engagement and retention.
Notification System
Critical payment reminders and transaction alerts suffered from delays and inconsistent delivery across SMS, email, and in-app channels. The system needed a reliable real-time notification infrastructure to maintain effective user communication.
Cost Optimization
Static infrastructure setup led to inefficient resource utilization and escalating costs during peak periods. The platform required intelligent scaling capabilities to optimize infrastructure expenses while maintaining performance.
Security Framework
Handling sensitive financial data demanded robust security measures and regulatory compliance. The challenge was to implement comprehensive data protection without compromising the platform's performance and user experience.
Our team worked closely with the client to re-architect their system, enhance UI/UX, and build a scalable, secure platform ready for growth. Key aspects of the solution included
Modern Cloud Architecture
We implemented a serverless architecture leveraging AWS Lambda and Kubernetes for dynamic scaling. The solution includes MongoDB as the database layer, optimized for high-availability and real-time transaction processing across the platform.
Intuitive User Interface
Our team executed a complete UI/UX overhaul for both web and mobile platforms using React Native. The redesigned interface features streamlined navigation flows and an optimized dashboard that prioritizes frequently used features for efficient user interaction.
Advanced Notification System
We developed a comprehensive notification infrastructure using AWS SNS and Twilio, enabling reliable multi-channel communications. The system incorporates WebSocket technology for instant in-app alerts, ensuring timely delivery of critical updates and payment reminders.
Intelligent Infrastructure Management
We designed a cost-efficient infrastructure utilizing AWS auto-scaling groups and strategic instance management. The system automatically adjusts resources based on real-time demand, optimizing operational costs while maintaining performance standards.
Enterprise-Grade Security
We implemented comprehensive security measures including end-to-end encryption and role-based access controls. The solution adheres to international data privacy regulations, featuring regular security audits and compliance monitoring protocols.
Our team achieved success which reflected growth, engagement, and satisfaction. Our team led to exceptional outcomes focusing on growing revenue and client base, elevating user satisfaction, and much more.
