About Us

We are building a new high-load online platform in the iGaming domain using a modern, cloud-based backend architecture.
Our focus is on performance, reliability, and correctness.

The platform is designed as a distributed microservices system, capable of handling real-time processing, financial transactions, and heavy concurrent workloads.

We are assembling a strong engineering team to design and implement this platform entirely in Python with FastAPI.

Role: Python Backend Developer

You will design and implement core backend services in a cloud-native, microservices architecture.
