At ООО «ЛОГИСТИКС-ТЕХ», I developed a REST API platform from scratch with Python and FastAPI. I also built services that exchanged data between corporate databases and warehouse terminals, including workflows for receiving, shipping, and inventory.
I developed asynchronous services with asyncio and connected systems through RabbitMQ, aio-pika, and Kafka. My integration work included external APIs such as OZON REST API, as well as file exchange over FTP and SFTP.
At СИН Технологии, I designed and developed a Python client for OPC UA to connect SCADA / PLC systems with corporate information systems. I worked on real-time and historical telemetry and developed backend services with Tornado and asyncio.
Across these roles, I wrote automated and integration tests, worked with PostgreSQL and other data stores, and supported legacy code. I also contributed to CI/CD configuration and production deployments.
