Our client is a leading retail bank based in Thailand, recognized for its extensive local presence and strong financial standing. The bank employs over 4,000 professionals and operates approximately 1,000 branches across the country. For the fiscal year 2023, the organization managed a substantial budget of $105 million, underscoring its commitment to growth, innovation, and customer-centric banking services.
The client faced two major challenges in their digital development efforts:
- Slow Feature Deployment: Their in-house development team was overwhelmed with a heavy backlog, causing delays of several months in rolling out new features. This slow pace hindered their ability to respond quickly to market demands and customer needs.
- Cost Optimization: They aimed to reduce development costs without compromising quality. The client looked for skilled developers who could deliver high-quality work at a more cost-effective rate compared to local resources.
To address the client challenges, SotaTek seamlessly integrated into the existing product team and accelerated the development of several key features, enhancing both functionality and user experience. Leveraging a modern tech stack, including .NET, Spring Boot, Swift, Kotlin, RabbitMQ, API Gateway, Redshift, Azure, AWS, Microservices, SQL, and Kafka, SotaTek delivered the following solutions:
- Credit Card & Loan Management: We developed a system for managing debt repayment, bill payment, and credit card transactions. Users can now monitor all credit card and loan activities in real-time, make payments, manage installment plans, and track or redeem rewards points. The feature was built with robust security measures such as biometric and two-factor authentication to ensure user data protection.
- Promotions & Coupons Application: A dedicated module was built to showcase the latest promotions and discounts. Users can easily browse, download, and redeem coupons directly from their mobile devices. The coupon repository allows seamless management of all available offers, significantly improving user engagement and retention.
- Cross-Bank Bill Payment System: To streamline the bill payment process, SotaTek implemented a cross-bank solution that allows users to manage and pay utility bills, credit card balances, loans, and recurring expenses across multiple banks. An intuitive interface enables users to add and monitor bills, while an integrated notification system alerts them of due dates, successful transactions, or payment issues.
- Smart Loan Feature: This feature digitizes the loan application process, removing the need for traditional paperwork and reducing the bank’s environmental footprint. Through the mobile app, users can apply for loans using a streamlined flow that integrates eKYC, online verification, and digital approval, making the entire process faster, smarter, and more sustainable.
