## Обо мне
Senior Python backend engineer. 12+ years on Python, 16+ years of professional IT experience. I build backend services and APIs, design architecture, optimize PostgreSQL and async pipelines. Solid background in both highload (billing, production-critical migrations) and regular product teams.

I'm a Python backend engineer. 20+ years in IT, 16+ years of professional experience, 12+ years on Python/Django.

**What I do:**
- backend services and REST APIs on Python/Django
- architecture and modular design
- PostgreSQL and SQL optimization
- async processing (Celery, RabbitMQ, Redis)
- integrations and search engines (OpenSearch / Manticore)

**Background — balance of two worlds:**

*Highload and production-critical systems* — 7 years at MegaFon: billing, rating, migrations without service downtime, 50x regression-test speedup.

*Regular product development* — DataArt (enterprise REST APIs, ORM tuning, integrations). Bolshaya Troyka (modular architecture, legacy refactor, OpenSearch/Manticore, GitLab CI, Ansible).

**Currently:** Senior Python Developer at Bolshaya Troyka (Moscow, remote).

**Values:** clean code, fast tests, clear interfaces, metrics and observability.
