AI-Powered Fintech Remittance App Development Using MAUI

We are a trusted fintech company with multiple industry recognitions, backed by a strong portfolio of live solutions delivered across various countries. Our experience comes from actual implementations of secure transactions, compliance, and scalability.

This case study focuses on a recent project undertaken by our client based in Australia. In our first meeting with Mark (the founder of PesaTransfers.com), he discussed his idea for a new fintech company named PesaTransfers, based out of Melbourne.

The overall aim of the company was to allow people to transfer money overseas faster, cheaper and easier than ever before, starting by offering transfers from Australia to Kenya, afterwards, they would begin offering transfers between other countries including Nigeria and Ghana.

They would also support users in the UK, US and Canada to send money quickly and easily to Kenya.

The challenge was to overcome common issues in cross-border payments, such as high fees and delays.

In order to enable instant transfers to M-Pesa accounts, bank accounts and mobile wallets, we needed to develop both mobile and web applications.

Building this ecosystem required us to connect to both Visa Direct and Currencycloud to enable instantaneous global transactions, automatic currency conversions and financial compliance features.

Our responsibility was to design and develop a scalable minimum viable product by creating a secure financial service payment infrastructure and complying with global standards for compliance in multiple currencies in multiple countries.

Cross border remittances are a lifeline for millions of families worldwide. Yet, traditional systems remain slow, costly, and fragmented.

PesaTransfers set out to change this by building a real time, compliant, and user friendly remittance platform connecting Australia to Africa, starting with Kenya and later expanding to Nigeria and Ghana.

This case study details how Adequate Infosoft successfully delivered the project using .NET MAUI for cross platform apps and Azure Cloud for hosting and compliance, resulting in a delighted client and a scalable fintech solution.

Client had provided vision details as follows:

Real Time Transfer :

To decrease the time of settlement period from days to minutes.

Low Fee Structure:

To provide FX rates competitively along with clear fee structure.

Access On Multiple Platforms:

The client requested that apps be developed for each of the following platforms: mobile (iOS & Android), desktop (windows & mac), web-based.

Compliance Oriented:

The application must include an overall process for compliance with Anti Money Laundering (AML), Know Your Client (KYC), and Payment Card Industry Data Security Standards (PCI DSS).

Scalability:

Be prepared to support multiple currencies, in various regions.

The project faced several industry wide hurdles:

• The legacy systems caused transfer times to take one day to up to three days.
• Foreign exchange fees are high therefore users lost money on the transaction that was completed.
• The ecosystem was very fragmented since it consisted of bank accounts; mobile wallets; and M Pesa.
• Regulatory complexity was a significant obstacle to automating the AML/KYC compliance obligations.

In the solution approach, Adequate Infosoft proposed a modular, cloud native architecture that contained the following pillars:

• Utilizing .NET MAUI Cross Platform Development means having one codebase for iOS, Android, Windows, and macOS.
• Using Azure as the cloud hosting service provides secure, scalable, and compliant infrastructure.
• Sliding scale, real time Visa Direct and Currencycloud integration allows for instant transfers and automatic FX conversion.
• M Pesa and Bank APIs allow for seamless payouts to wallets and accounts without needing to use a separate application.
• Embedded compliance enables for automated KYC/AML verification and audit trails.

Phase 0 : Initiation

• NDA and contract finalization.
• Project kickoff with client stakeholders.
