We work with a modern tech stack, including:
- Python (asyncio)
- Messaging and streaming: RabbitMQ, Kafka
- High-load scenarios and distributed computing
- Scalable and fault-tolerant infrastructure
- #NODJANGO :)

- Write functional and integration tests to ensure system stability
- Collaborate with developers, QA, analysts, and product teams, while contributing to code reviews and knowledge sharing

- RabbitMQ (RPC, pub/sub, DLX, retries)
- MongoDB (indexes, configs, transactions)
NICE TO HAVE
