Semen Teneshev

Python Backend Developer

I build backend services, asynchronous APIs, task-processing pipelines, and integrations with external platforms.

My main stack is Python, FastAPI, PostgreSQL, SQLAlchemy, Redis, Celery, and Docker. I have commercial software development experience since 2022, including backend systems built from scratch and maintained in production.

I am open to remote Python Backend opportunities.

Core stack

  • Backend: Python, FastAPI, AsyncIO, REST API, Pydantic
  • Data: PostgreSQL, SQLAlchemy, asyncpg, Alembic, Redis
  • Background processing: Celery, task queues, scheduled jobs
  • Infrastructure: Docker, Nginx, Linux, Git, GitLab CI/CD
  • Integrations: Telegram Bot API, VK API, payment webhooks, OpenAI API
  • Also worked with: ClickHouse, React, TypeScript, C#, Unity
