Executive Summary

Project Overview

A US-based Sports Event Management SaaS company required a modern, scalable, and secure backend ecosystem capable of supporting rapid platform growth while simplifying payment operations and financial workflows. Our team delivered a scalable AWS-powered backend solution using .NET 8 and an event-driven architecture that streamlined operational processes while improving reliability and platform scalability.

The Problem

Business Challenges

Platform Scaling Constraints

Existing architecture required modernisation to support growing customer demand and multi-tenant onboarding at scale.

Subscription & Billing Complexity

Managing recurring subscription plans across multiple organisations introduced significant operational overhead.

Manual Financial Operations

Accounting reconciliation and financial reporting processes required costly manual intervention at every cycle.

Security & Compliance Requirements

Secure access control and authentication were essential for protecting user data and financial transactions.

Zero-Downtime Reliability

Business operations demanded high availability and seamless deployments with no disruption to live events.

The Solution

Architecture Design

We designed and implemented a cloud-native, event-driven backend architecture using best-in-class tools for each layer — ensuring scalability, security, and full automation of financial workflows.
