SUMMARY
GitHub
Backend Python Developer with 1+ year of commercial project
Telegram experience in Django and FastAPI. Specialized in building RESTful APIs,
async task processing (Celery + Redis), and web scraping systems with
Ukraine, Kharkiv semantic search (Scrapy, pgvector, sentence-transformers).
Experienced with PostgreSQL/Supabase, CI/CD (GitHub Actions), and
SKILLS cloud deployment (AWS EC2, Render). Strong problem-solver,
comfortable owning a project end-to-end.
