Backend Python Developer

Deployed docker on a server via dockerfile and docker-compose, where I migrate code from Java to Python. Configured nginx. Developed and continue to create new API-methods asynchronously (FastAPI, async) for the indicator throwing requests. Started a parser on selenium, for parsing data by APScheduler, and then placing them in the database asynchronously. I have developed a database architecture (postgresql) with indexing of necessary fields (one of the tables has rows >170mln); I know how to build optimised and complex queries with nested subqueries and with temporary tables. Sometimes I update the database structure, because technical task is technical task, and life is life. I know how to use alembic (data migration). I interact with the database via ORM (sqlalchemy, async; pydantic for data validation). After increased load on the server due to selenium, as more data had to be parsed, I solved the problem by switching from selenium to selenoid (Go). Now I implement docker swarm to distribute the load of all containers. Developed the indentification/authentication/authorisation (JWT) functionality. Then replaced this by sending the client account number in encrypted form, which I check against the existing one in the database and its activity (activated or not). Skills: FastAPI · Docker · SQLAlchemy · PostgreSQL · Git · Selenoid · Teamwork · Redis · Python (Programming Language) · RDBMS · Database Administration · asyncio
