Could you tell us more about your experience at Alfa-Investments?

At Alfa-Investments, I worked as a Python developer, focusing on developing and maintaining internal services for processing financial data and automating trading processes. My main tasks included integrating with external APIs, processing large volumes of data, and writing scripts for market data analysis.

For example, I implemented a module for collecting and aggregating real-time quotes using the asyncio library, which significantly increased data processing speed and reduced system load.

import asyncio

async def fetch_quote(symbol):
    # asynchronous API request
    pass

async def main():
    symbols = ['AAPL', 'GOOG', 'MSFT']
    tasks = [fetch_quote(sym) for sym in symbols]
    results = await asyncio.gather(*tasks)
    print(results)

asyncio.run(main())

I also participated in optimizing ETL processes and writing unit tests to ensure code reliability.
