Stock market data stream integration

Creating a trading pipeline, need to integrate with data source (https://polygon.io/docs/websockets/getting-started) and create python based pipeline from scratch. Will add more features later on (if preliminary work is good) like the trade executions, trade algorithms (derived from this data source). This is a start to High frequency trading and automating the whole flow eventually.

Ideally looking for an independent part time developer who will work with me (no agency/companies with fixed price modeling)

Ideal candidate - Have basic stock market experience, python and back-end experience. Basically know what they're doing. Please reach out if you have more questions.
