Backend Engineer at Hotan Games building operator-to-provider workflows and distributed gaming platform infrastructure.

At Hotan Games, I designed core operator-to-provider integration workflows for a new gaming platform and deployed Linux infrastructure across three virtual servers. I also implemented Redis and BullMQ background processing, real-time communication, and load tests simulating 2,300 concurrent virtual users.

Previously, I engineered a Temporal-based bot orchestration system and improved key application response times from approximately 400–500 ms to 70–120 ms after migrating infrastructure. At Clicker Games, I led backend architecture for a platform that grew to 80,000 registered users, moving services from a monolith to microservices and building scalable APIs and workflows.
