Sarwa Real Estate Investment

To efficiently deliver a consistent experience across Android, iOS, and web platforms, we used Flutter with the Dart programming language. This approach allowed us to maintain a single code base, which greatly accelerated development while simplifying maintenance. The app was built using the BLoC architectural pattern, which provides robust and scalable state management.

We first launched a mobile app for stores and later extended it to the web using Flutter Web. The transition was quick and smooth – we were able to adapt the app to web standards and new designs in just a few weeks.

On the web side, we created an intuitive admin panel to give administrators full control over investment-related content. The panel allows administrators to manage user profiles, customize investment data, and trigger key investment events such as distributions or NAV updates.

It also includes a rich text editor for creating and formatting content, as well as tools for uploading and organizing multimedia files such as images and PDFs. Email communications are fully managed from the panel, making it easy to configure and send timely, branded messages to users.

The backend was built using a REST API architecture to ensure seamless communication across platforms. We used NestJS for the application logic and PostgreSQL hosted on Amazon RDS for the database. The architecture follows a hexagonal pattern, which helps separate the core domain logic from external services and makes the system easier to scale and maintain.

For authentication and security, we integrated Amazon Cognito along with Google Authenticator to provide two-factor authentication for administrators. Notifications are handled by Amazon SNS for push and SendGrid for email, giving the application a reliable and scalable messaging system that supports real-time interactions.

We began the design phase with a collaborative workshop to map out the complex logic behind the investment process early on. Starting with wireframes for the investor app and admin panel, we ensured that all user flows were clear and aligned with business goals.

The visual design was built around the client’s existing brand identity. We created a UI kit and high-fidelity designs covering all app states to speed development. Designs were created in Figma, with regular feedback loops during weekly and daily check-ins to balance business needs with technical constraints.

We began development with a focus on delivering an MVP that captured the core value of the product. After the initial release, the client paused to gather user feedback that shaped the direction of future updates. When we returned, we moved to a continuous delivery model with a clear product goal for each new release.

Our team now works in Kanban, using select Scrum practices such as regular backlog grooming and planning sessions. Feature prioritization is driven by the impact/effort matrix, allowing us to focus on delivering high-impact updates efficiently. We’re currently preparing for the launch of Sarva V3 – a version shaped by iterative development, user insights and close collaboration with the customer.
