1. Ecommerce shop

Laboratory Shop is a production‑ready, scalable Telegram‑based vape shop built with FastAPI, PostgreSQL, Redis, Docker and deployed to a Linux server. Originally launched for real‑world users (now closed by the founder), it features:

• Fully functional online catalog
  Browse products, add items to cart, submit orders — all from within Telegram.
• Scalable, containerized deployment
  Each service (Bot, Redis, PostgreSQL) runs in its own Docker container, orchestrated via Docker Compose for easy horizontal scaling.
• User authentication & order management
  Secure login via Telegram OAuth, persistent carts in Redis, and order records in PostgreSQL.
• Telegram‑based admin dashboard
  Managers can view and manage orders, inventory, and customer analytics directly in Telegram (currently migrating to a Django web admin).
• Robust data storage
  • PostgreSQL as the primary relational database for products, users, orders and reviews.
  • Redis for fast, in‑memory cart sessions and rate‑limiting.
• Clean, modular architecture
  Follows SOLID principles and uses SQLAlchemy ORM + Alembic for migrations.

• CI/CD ready
  Automated Docker builds and deployments via GitHub Actions.

  Well‑structured RESTful endpoints for recipes, user authentication, comments, and ratings—built with FastAPI’s dependency injection and Pydantic models.
• Test Coverage
  Comprehensive pytest suite covering all endpoints with fixtures, parametrized tests, and containerized sessions—maintaining test database.
• Monitoring & Observability
  Prometheus metrics exposed by each service, visualized in Grafana dashboards; structured request logging and alerting via Alertmanager.
• Scalable Deployment
  Containerized microservices orchestrated with Docker Compose (easily portable to Kubernetes), including:
  • API Service
  • Auth Service
  • Databases (PostgreSQL)
  • Grafana and many other observability services.
