Executive Summary

MeridianBet is a global leader in sports betting, with a significant footprint in Tanzania. They faced a critical need to modernize their Jackpot offering—a core engagement driver where users predict outcomes of multiple matches to win massive prizes. Their existing solution was rigid, difficult to scale on match days, and lacked the flexibility to offer diverse jackpot types.

Devson engineered the Online Sports Jackpot, a high-performance predictive gaming platform. Built on .NET 7 for raw speed and Vue.js (Quasar) for a premium mobile-first experience, the system seamlessly integrates with MeridianBet's core implementation ("Vegas" and "GREMS").

The solution supports complex ticket creation, real-time result automated settlement, and even USSD integration for feature-phone accessibility. The launch resulted in a robust, scalable platform capable of handling thousands of concurrent ticket submissions during peak Premier League windows without a hitc

The Challenge

The Bottleneck of Success

Use of sports jackpots spikes dramatically in the hour before kick-off. MeridianBet's legacy infrastructure struggled to handle these "thundering herd" moments, leading to failed transactions and frustrated users. Furthermore, their previous system was a "black box," making it difficult for their internal trading teams to configure new jackpot structures or settle markets quickly.

Complex Integration Requirements

The new system couldn't exist in a vacuum. It had to integrate deeply with the "Vegas" player wallet system for secure fund deduction and payout, as well as the "GREMS" API for match fixtures and resulting. Any latency or error in these integrations would mean direct financial loss or player churn.

The Mobile-First Mandate

With the majority of the African market accessing the web via mobile devices (often on unstable connections), the frontend required an architecture that was lightweight yet resilient.

Performance Spikes

Handling massive "thundering herd" traffic just before match kick-offs.

Legacy Integration

Deep integration with existing wallet (Vegas) and odds (GREMS) systems.

Mobile Constraints

Delivering a premium experience on unstable mobile connections.

Our Solution

We delivered a Cloud-Scale Jackpot Engine designed for speed, reliability, and user retention.

Architecture & Backend Power

We utilized .NET 7 and Entity Framework Core to build a high-throughput API. By adopting the CQRS (Command Query Responsibility Segregation) pattern with MediatR, we separated the high-volume "read" operations from the critical "write" operations. This ensured that even if thousands of users were browsing outcomes, the transactional integrity of placing a bet was never compromised.

Premium Frontend Experience

For the user interface, we chose Vue.js 3 within the Quasar Framework. This allowed us to build a single codebase that delivers a native-app-like experience in the browser. Key features include:

Smart Ticket Builder: An intuitive interface for selecting outcomes across 13+ matches.
Real-Time Validation: Instant feedback on wallet balance and ticket validity.
Offline Resilience: Pinia state management ensures user selections aren't lost if connectivity flickers.

We also built custom "Infrastructure" adapters to communicate with MeridianBet's Vegas and GREMS systems, including robust retry policies and transaction logging.

Key Features

Dynamic Jackpot Engine

Administrators can configure virtually any type of sports jackpot (e.g., "Pick 13", "Correct Score") with custom rules and automated payouts via a secure portal.

Cross-Channel Betting

A unified backend powering both the rich web interface for smartphones and a lightweight USSD API for feature phones, ensuring universal access.

High-Resilience Processing

CQRS architecture with optimistic concurrency control ensures every ticket is processed accurately, even when thousands submit simultaneously.
