Multi-Bank Digital Payments Platform (10,000+ Users)
Solution and architecture consulting, mobile and web development, end-to-end cloud setup and BaaS/payment-processor integrations — powering seamless connectivity between multiple banks and 10,000+ users.

Problem Statement
A US fintech had a bold idea for a digital payments product but needed to get from concept to a credible, scalable MVP fast. Doing so meant designing the right architecture, building polished mobile and web experiences, standing up secure cloud infrastructure, and integrating with Banking-as-a-Service providers and payment processors — all under the compliance expectations of financial services.
They needed a partner who could own the full stack of that journey and connect multiple banks and thousands of users on a single platform.
- Concept-stage product needing a credible, scalable MVP quickly.
- Complex integrations with multiple banks, BaaS and payment processors.
- Cloud infrastructure to build and secure from scratch.
- Financial-grade security and compliance from day one.

Solution Overview
Trusty Bytes took the product from architecture to launch. We consulted on a best-fit solution architecture, built cross-platform mobile apps and a web portal, and set up and managed the entire cloud infrastructure. We then integrated with Banking-as-a-Service providers and payment processors to deliver seamless multi-bank connectivity.
The platform now connects multiple banks and supports over 10,000 users — a credible, scalable MVP that grew into a live payments product.
A secure, service-oriented backend (Node.js APIs, PostgreSQL) sits behind a React web portal and React Native apps. OAuth2-based authentication and encryption protect user and financial data, and integrations to BaaS and payment processors are abstracted behind internal services for resilience.
The AWS cloud environment was designed for security and scale — isolated networks, managed secrets, observability and CI/CD — so the platform could grow from MVP to thousands of users without re-platforming.
