Werdegang

Berufserfahrung von Sergei Firsov

  • Bis heute 9 Monate, seit Sep. 2024

    Senior Software Engineer

    AISA IT-Service

    In my role as a senior software engineer, I drove a project architecture overhaul using DDD and Clean Architecture, improving performance by transitioning to microservices (HTTP/gRPC/RabbitMQ). I optimized code with asyncio and related async tools, increasing service capacity by 20%. I also authored documentation, tests, and set up automated deployment via GitLab CI with Docker and Compose, including advanced networking.

    Software Engineer

    AISA IT-Service

    As a software engineer, I focused on stabilizing systems by fixing bugs and reducing technical debt. I successfully migrated the project from Flask to FastAPI to enable seamless integration of asynchronous libraries. Additionally, I built an internal task-tracking bot using a locally deployed Ollama server and custom neural networks, enhancing team efficiency.
