Senior Software engeener
I'm happy to be in the top-qualified engineering team focused on top-tier frameworks and tools for metagaming backend development and MMO game operation solutions.
I'm deeply involved in the design and development of the MMO metagaming framework core, libraries, tools, and custom operation solutions with Kubernetes (k8s operators, controllers). The framework aims to operate with the workload of millions of concurrent users, with smooth and easy scaling, and load balancing. It's built mainly on Python and Rust but it provides a language-agnostic solution with the support of Python, Java/Kotlin, .NET, C++, and TypeScript.
As a component lead, I also built the solution for a DDoS protection system implemented with Kafka streams on Scala with a target throughput of about 200K RPS.
- Metagaming framework libraries and tools design and development.
- Metagaming backends development.
- Performance testing tools and optimization.
- Scaling solutions development.
- Monitoring operations solutions support and development.
- Grafana plugin development.
- Kubernetes custom operators development.
- Code review and support of other teammates and various projects.
Main tech stack:
Python, Rust, Java/Scala, Typescript, Docker, Kubernetes, Helm, Kafka, Kafka-streams, KSQLDB, Mongodb, Redis, Prometheus, Loki etc... etc...

Telepado
Senior Software Engineer / Team Lead
Starting as a Senior Engineer soon I became the backend team lead. My main responsibility was team management, system architecture design, and development of the messaging platform for Telepado and Meetora messaging apps.
The service was made to provide high availability, throughput, and low latency. The service supports secure messaging audio calls, and group calls. And can be enabled as a white-label solution.
I was highly involved in the development of
- Core components of the platform;
- Language, and code generator for the services API with the support of API calls versioning for long-term backward compatibility which allows seamless upgrading of the services and clients;
- Java client library for Android. To provide a better performance and reduce battery usage I had to implement a custom NIO layer using the restricted subset of Java NIO API available on Android.
Further, I lead the development of the Seekwa project. The platform for live mentorship and learning. The platform's core was based on the Telepado messaging engine using its communication capabilities. One of the most challenging parts was billing implementation. We have developed the custom payment system integration layer which allows the smooth integration of almost any payment provider like Stripe and PayPal supporting internal accounting and payouts.
Technologies used: Scala, Akka, Akka Streams, Kafka, Cassandra, Redis, Twitter Zipkin, Zookeeper, Elasticsearch, ELK Stack, AWS.
