Partnering with HyperSense: Elevating Tinka's Mobile App Experience

Business challenges or needs that led to the project

In 2019, Tinka approached our experienced mobile application development team with the goal of creating a cutting-edge mobile app to enhance user acquisition and engagement. Within less than two years, this platform has evolved into their primary channel, and we continue to expand and maintain its functionality. Tinka's app empowers customers with greater control and insight into their payments, personal data, balance, and invoices, aligning with the company's mission to make shopping more accessible, equitable, and responsible for all.

company background

Although Tinka has an in-house software development team, they sought the collaboration of HyperSense due to our extensive expertise in mobile application development, an area where their team lacked proficiency. This strategic partnership enabled Tinka to leverage our specialized knowledge, ensuring the creation of a high-quality, user-friendly app that aligns with their mission and continues to drive their success.

Developing Tinka's Innovative Mobile App: Agile Collaboration and Cutting-Edge Technologies

Software development methodology

In our collaborative software development process, both Tinka and HyperSense have embraced the Agile methodology . The seamless alignment of our methodologies has been facilitated by our mutual use of popular systems like Jira and Slack, which have proven easy to integrate. Our mobile development team works in close coordination with Tinka's Product Managers, Product Owners, designers, and backend developers, resulting in a highly efficient and well-orchestrated collaboration.

Projects

This synergy has allowed us to maximize productivity and streamline the development and maintenance of Tinka's innovative mobile app, ensuring it continues to exceed customer expectations and drive the company's growth.

Technology stack and tools used

In terms of the technology stack and tools utilized for our collaboration with Tinka, we employ a diverse and modern set of resources to ensure a streamlined development process. Figma is our go-to tool for designing the user interface, while we rely on Flutter as the development framework for the mobile app, allowing us to create a high-quality, cross-platform experience. For task tracking and project management,Jira is our platform of choice, ensuring that tasks are assigned and monitored effectively.

Slack serves as our primary communication tool, fostering efficient and real-time conversations between team members from both companies. Additionally, we use Miro for brainstorming, visual collaboration, and mapping out ideas, while coda.io assists in creating dynamic, collaborative documents and managing project information. This comprehensive suite of tools enables our teams to work seamlessly together, driving the successful development and ongoing maintenance of Tinka's mobile application.

Continuing with the technology stack and tools employed, Flutter serves as the primary framework for developing Tinka's mobile application, offering a highly efficient and versatile solution for crafting a smooth, cross-platform experience. For some backend microservices, we utilize AWS CDK with TypeScript, ensuring a robust and scalable infrastructure that supports the app's performance.

Firebase plays a critical role in providing various essential features, such as push notifications, remote configurations, deep linking, analytics, and A/B testing. By integrating Firebase, we can optimize user engagement, monitor performance, and make data-driven decisions to continually enhance the app's functionality and overall user experience.

This diverse and powerful set of tools allows our teams to work in harmony, propelling the successful development, evolution, and maintenance of Tinka's innovative mobile application.

Key features and functionalities

The Tinka mobile app offers a diverse range of user-friendly functionalities, designed to streamline access to Consumer Credit, Spread Payment, and Buy-Now Pay-Later financial products . This fintech mobile app simplifies the process of purchasing online loan products for Tinka's customers.

One of the app's key features is passwordless login, allowing users to access financial products without the hassle of remembering passwords. Instead, users receive a one-time code or link via email after entering their email address, which they can use to log in.

Tinka provides easy access to consumer credit, enabling users to receive funds directly through the app without waiting in long bank queues. The company also offers a physical credit card for versatile in-store (offline) payments. However, the most popular feature is the Buy Now - Pay Later (BNPL) option, which allows users to purchase items and choose a later date to pay or spread payments over several months. Users can also choose from various credit products, payment arrangements, or loans that best suit their needs.

Security is paramount, with biometric security, credit risk calculation, and fraud prevention measures in place. Users can also access Tinka's in-app chat support for assistance.

Account management features ensure users stay informed, with optional push notifications providing updates. The app also implements the latest standard in KYC (Know Your Customer) processes, utilizing iDIN for advanced identity verification. With these comprehensive features, the Tinka app offers a seamless and secure experience for customers seeking flexible financial solutions.

Duration, milestones and team

Our collaboration with Tinka began in 2019, with an initial project delivery timeline of six months. To ensure an efficient and flexible development process, we adopted the Agile Scrum methodology, working in 200-hour sprints.

The initial team consisted of 2 senior Flutter developers, who were responsible for crafting the app's core functionality and user experience. Over the years, we have delivered more than 8,000 hours of development work, continually refining and expanding the app's features.

Throughout our collaboration with Tinka, we have consistently adapted to their evolving needs by scaling the team up or down as required. This flexible approach optimizes Tinka's costs, ensuring that resources are allocated efficiently and effectively. By maintaining this level of adaptability, we can provide the necessary support and expertise for the ongoing development and success of Tinka's innovative mobile application.

Duration

In early 2022, a senior backend developer joined the team, focusing on AWS CDK to develop essential backend microservices that support and enhance the app's capabilities. With this expanded team, we continue to work closely with Tinka, ensuring the ongoing success and growth of their innovative mobile application.

As the Tinka app has become the primary driver for consumer reach, there are plans to scale up both the Flutter and Backend teams to accommodate the increasing demand for new features and enhancements. Additionally, we will allocate a full-time QA engineer dedicated to writing a comprehensive set of end-to-end automated tests. This expansion will ensure the app maintains its high quality and continues to meet the evolving needs of Tinka's growing customer base.
