This Australian company, known for helping people transfer money across borders, realized their mobile app wasn’t keeping up with their rapid growth. They needed to improve the app’s speed, security, and overall user experience. That’s where VE came in. The firm sought to upgrade its app into a user-friendly, secure tool for global payments, and they hired VE’s mobile development team to make that happen.
Sure, the client could’ve hired local developers, but they were looking for something specific—technical expertise that went beyond fixing bugs. VE was known for providing skilled resources who could tackle complex mobile app issues while offering flexible, scalable solutions. After discovering VE through an online search, they made the decision to go with a team that could deliver results.
Frequent app crashes and a non-intuitive user interface leading to reduced user satisfaction.
The Android application's stability issues were addressed by a developer proficient in Java and Kotlin, while the user interface of the iOS application was revamped using Swift, aiming to enhance the overall user experience.
Java helped make the Android app more stable and crash less. Kotlin added new features that made the app work better. Swift made the iOS app easier and nicer to use. XML was used to design a layout that's simple to navigate for all kinds of users, which made them more likely to use the app.

Slow transaction processing and lack of transparency in currency exchange rates.
Integrated the powerful Remittance SDK third-party library for simplified cross-border transactions, making them faster and more efficient.
By selecting the Remittance SDK, the application benefited from its efficiency in handling international transactions. This integration not only reduced processing times but also provided clearer exchange rate information, thereby enhancing user trust and satisfaction.
Need for high-level security and multi-language, multi-device compatibility.
Implementation of MD5 and AES 256 encryption, robust firewalls, Retrofit Network Library for API communication, and GSON and XML Parser for data parsing.
MD5 and AES 256 made the app a lot safer. Retrofit helped the app work smoothly in many languages and on different devices. GSON and XML Parser made sure the app handled data correctly and quickly, which is important for users all over the world.
VE’s developers brainstormed various approaches to tackle the app’s stability issues and enhance its user interface.
Java was chosen for its superior performance and integration with Android SDK, compared to Python's slower execution and less native support for Android app development.
Swift was selected for its modern syntax, safety features, and faster performance, offering advantages over Objective-C in terms of ease of use and efficiency.
The Remittance SDK was preferred for its specific optimization for cross-border payments, which other general SDKs lacked.
This wasn’t just a case of outsourcing. VE’s mobile developers worked closely with the client as an extension of their own team.
The client shared the task list on Jira, the developers used that to monitor project progress.
GitHub was utilized to track changes and facilitate communication regarding modifications to the project. This platform enabled transparent and efficient collaboration.
Firebase Crashlytics was utilized for monitoring the app for any issues or bugs. This allowed for swift and efficient detection and resolution of problems, ensuring smooth app functioning.
After six months of dedicated work, the team significantly revamped the mobile app, incorporating diverse payment options, instant alerts, and reliable security protocols approved by the Financial Conduct Authority (FCA).
The app's user-friendly and secure design is steadily driving the client towards becoming a significant player in the remittance industry.
The streamlined processes diminished the dependence on conventional methods, lowering expenses.
The app's compatibility with Android and iOS opened up new global markets, enlarging the user base.
The focus on reliable security and user contentment led to favorable customer reviews, enhancing the brand's credibility.
