Production Client ProjectCompletedGaming Backend Platform

iGaming Platform

Production backend for a multi-provider gaming platform — architected services supporting 1,200+ games with real-time session management, multi-provider wallet operations, and idempotent transaction processing.

The Challenge

A gaming platform needed a unified backend to integrate multiple external gaming providers, each with different APIs, while maintaining transaction consistency and real-time session management at scale.

Engineering Solution

Built a modular monolith backend with NestJS supporting 1,200+ games across 2 direct certified providers (OnlyPlay, Jacktop) and 1 major aggregator (EGS) integrating 25+ studios. Implemented idempotent transaction handling, secure callback validation, and reconciliation pipelines.
